AB  - Research conducted on 16 dairy farms in Serbia has shown that poor housing conditions represent one of the major dairy cows’ welfare problem in our country. This is also an area of animal welfare in which the greatest difference in relation to the situation in EU countries can be observed. Poor comfort conditions are estimated based on a high share of cows that lie outside their lying area (36.5%) as a consequence of inadequate or insufficient  size of lying areas. Investigated the farms showed a very poor state of hygiene of dairy cows, with a high percentage of cows with the contaminated lower parts of the legs (84.6%), rump (71.3%) and udder (60.0%), which indicates the inadequate hygiene of lying areas and facilities, insufficient amount of bedding but also disorders of rumen digestion. The biggest welfare problems are present on farms with tied system, also the presence of grazing in our conditions, unlike the EU, is also insufficient from the standpoint of ensuring the welfare of dairy cows.

AB  - To test the variability of traits of Simmental bulls in performance test, data of the Livestock - Veterinary Centres for Reproduction and Artificial Insemination of Velika Plana and Krnjača were used. In the analysis, data on 113 performance tested bulls born from 2008 to 2009 were used. The analysis included two sets of characteristics: body development traits and growth traits. The average body mass of calves entering the test was 195.75 kg, while the body mass at the end of the test was 476.50 kg, average daily gain in the test was 1138.69 g. Average values of body development traits measured at the end of the test, with 12 months of age were: height at withers 127.13 cm, chest circumference 179.42 cm, the chest depth 61.19 cm and body length 151.34 cm. The influence of their sires, the year and the Centre on the variability of traits was studied. The effect of age is present at a high level of statistical significance (p (lt) 0.01) for all traits that are registered at the end of the test, while the effect of the Centre was present in the variability of body mass at the end of the test, the daily gain in the test and the length of the body. The bulls-sires' influence was demonstrated (p (lt) 0.05) on the variability in body mass of calves entering the test.

AB  - Whole-plant corn silage is a starting point for economical and modern animal husbandry. It is a quality green feed replacement and the most important cattle feed. The quality of whole-plant corn silage is of great importance in milk production. Continuous monitoring of silage quality is an important part of feeding programmes. The aim of this study was to use chemical and microbiological analyses to determine the quality of whole-plant corn silage produced on family farms. The analysed samples contained, on average, 66.37% moisture (58.79-72.01%), 33.63% dry matter (27.99-41.21%), 2.07% crude protein (1.07-3.06%), 1.26% crude fat (0.72 -1.84%) and 8.09% crude cellulose (5.72-9.98%). The average pH value, taken as an indicator of the quality of fermentation, was 3.90 (3.50-4.16). Total volatile fatty acid comprised 1.87% (0.67-2.47%) lactic acid, 0.68% acetic acid (12.20-1.52%) and 0.02% (0-0.27%) butyric acid. The average proportions of lactic, acetic and butyric acids in the silage were 72.80% (33.3-88.81%), 26.45% (9.35-66.67%) and 0.75% (0-10.16%). The authors determined silage quality using the Flieg score. The samples from 12 farms were graded as very good, while the silage from the other farms was evaluated as good (4 farms) and satisfactory (2 farms). The analysis of microbiological quality showed that the samples on average contained 405,556 (10,000-3,000,000) of silage bacteria and 7,000 (0-80,000) of mould. Sulphate-reducing Clostridia and Salmonella were not identified. The samples matched quality requirements prescribed by the rulebook.

AB  - Lifetime milk production is a key success factor in fulfilling the production potential of high-yielding cows. Lifetime milk production traits are pronouncedly variable. The life expectancy and the length of productive life of dairy cows are repeatedly limiting factors for improving lifetime milk production. Lifetime milk production is greatly depended on age at first calving and the number of lactations during productive life. Previous researches have implied there are real chances for improving the lifetime milk production of high-yielding cows. The goal of this research was to investigate the significance of key systematic factors on the lifetime production of high-yielding Black-and-White cows. The animals included in the sample had different share of Holstein genes. The researchers determined systematic factors that caused some significant phenotypic variations of the investigated trait. The average lifetime milk production was 25,002.66±7,755.39 kg. When observed by cow genotypes, the mean values of the lifetime milk production varied from 27,061.37 kg ( (lt) 58% HF) and 24,761.26 kg (58-73% HF) to 23,185.36 kg (>73% HF). The differences in lifetime milk production determined among the animals were due to a highly significant (p≤0.01) impact of the bulls - the sires of the cows and the year of culling; the impact of the class of HF genes was significant (p≤0.05), whereas the impact of the reason for culling was non-significant (p>0.05).
AB  - Osobine životne proizvodnje visokomlečnih krava imaju veliki ekonomski značaj. Crno-bela goveda imaju značajan genetski potencijal za proizvodnju mleka. Visokoproizvodne krave crno-bele rase izložene su tokom produktivnog veka velikom broju složenih uticaja koji intenzivno deluju na nivo relizacije njihovog genetskog potencijala. Uslovi sredine često nisu u saglasnosti sa potrebama ove visokomlečne rase goveda. Povećanjem učešća gena holštajn-frizijske rase, tokom procesa oplemenjivanja evropskog tipa crno-belih goveda, došlo je do povećanja prinosa mleka. Dosadašnja istraživanja ukazuju na mogućnost za značajnije povećanje životne produktivnosti crno-belih krava. Poznavanje broja i nivoa uticaja faktora sredine, na životnu proizvodnju visokomlečnih krava, važno je zbog njihovog uključivanja u model. U skladu sa značajem pojedinih sistematskih faktora u okviru istraživanja je obavljena njihova objektivna procena. Cilj rada je bio da se primenom odgovarajuće metodologije ispita značajnost razlika, u ostvarenoj životnoj proizvodnji mleka kod visokoproizvodnih crno-belih krava, preko najvažnijih sistematskih uticaja. Prosečna životna proizvodnja mleka iznosila je 25002.66±7755.39 kg litara. Posmatrano po genotipovima krava prosečne vrednosti životne proizvodnje mleka iznosile su 27061.37 kg ( (lt)  58% HF), 24761.26 kg (58-73% HF) i 23185.36 kg (> 73% HF). Utvrđene razlike između grla u pogledu ostvarenog nivoa životne proizvodnje mleka nastale su kao posledica visoko značajnog uticaja (P≤0.01) bikova-očeva krava i godine izlučenja krava, klasa HF gena krava imala je značajan uticaj (p≤0.05), dok razlog izlučenja nije imao značajan uticaj (P>0.05).

When observed by cow genotypes, the mean values of the lifetime milk production varied from 27,061.37 kg ( (lt) 58% HF) and 24,761.26 kg (58-73% HF) to 23,185.36 kg (>73% HF). The differences in lifetime milk production determined among the animals were due to a highly significant (p≤0.01) impact of the bulls - the sires of the cows and the year of culling; the impact of the class of HF genes was significant (p≤0.05), whereas the impact of the reason for culling was non-significant (p>0.05)., Osobine životne proizvodnje visokomlečnih krava imaju veliki ekonomski značaj. Crno-bela goveda imaju značajan genetski potencijal za proizvodnju mleka. Visokoproizvodne krave crno-bele rase izložene su tokom produktivnog veka velikom broju složenih uticaja koji intenzivno deluju na nivo relizacije njihovog genetskog potencijala. Uslovi sredine često nisu u saglasnosti sa potrebama ove visokomlečne rase goveda. Povećanjem učešća gena holštajn-frizijske rase, tokom procesa oplemenjivanja evropskog tipa crno-belih goveda, došlo je do povećanja prinosa mleka. Dosadašnja istraživanja ukazuju na mogućnost za značajnije povećanje životne produktivnosti crno-belih krava. Poznavanje broja i nivoa uticaja faktora sredine, na životnu proizvodnju visokomlečnih krava, važno je zbog njihovog uključivanja u model. U skladu sa značajem pojedinih sistematskih faktora u okviru istraživanja je obavljena njihova objektivna procena. Cilj rada je bio da se primenom odgovarajuće metodologije ispita značajnost razlika, u ostvarenoj životnoj proizvodnji mleka kod visokoproizvodnih crno-belih krava, preko najvažnijih sistematskih uticaja. Prosečna životna proizvodnja mleka iznosila je 25002.66±7755.39 kg litara. Posmatrano po genotipovima krava prosečne vrednosti životne proizvodnje mleka iznosile su 27061.37 kg ( (lt)  58% HF), 24761.26 kg (58-73% HF) i 23185.36 kg (> 73% HF). Utvrđene razlike između grla u pogledu ostvarenog nivoa životne proizvodnje mleka nastale su kao posledica visoko značajnog uticaja (P≤0.01) bikova-očeva krava i godine izlučenja krava, klasa HF gena krava imala je značajan uticaj (p≤0.05), dok razlog izlučenja nije imao značajan uticaj (P>0.05).",

All first calving animals were on the farms of individual farmers in the municipalities of Kragujevac and Mladenovac. The research included the influence of bull sires, year and season of calving on milk yield and fertility. Least squares method was used to determine the average duration of lactation of 323.74 days. For a period of 305 days, heifers produced 3701.67 kg of milk, or 3644.58 kg of 4% FCM. The average production of milk fat was 144.26 kg and milk fat content was 3.88%. The interval from calving to first insemination lasted in average 124.19 days, and the animals were first calved at the age of 789.95 days. The bull sires had a highly significant effect (P (lt) 0.01) on the duration of lactation, milk yield and 4% FCM, milk fat yield and content and age of cows at first calving. The duration of service period was not under significant effect (P>0.05) of bull sires. Year of calving had a significant effect (P (lt) 0.01) on the duration of lactation, production of milk, milk fat and 4% FCM. Milk fat content, service period and age at first calving did not show significant variation due to the impact of different years of calving (P>0.05). Season of calving of cows demonstrated highly significant effect (P (lt) 0.01) on the production of milk and 4% FCM, and significant (P>0.05) on the production of milk fat, however it had no effect (P>0.05) on the milk fat content, duration of lactation and service period and age at calving.

AB  - The paper describes the state of the livestock production in the Republic of Serbia including preliminary results from the 2012 census: according to preliminary data, 908.990 heads of cattle, 3.403.288 pigs, 1.729.278 sheep and 235.576 goats are reared in Serbia. Structural and institutional measures, and measures of credit support should be the main instruments for achieving the goals of progress in animal husbandry. Activities in the breeding-selection work should be carried out in accordance with the recommendations of international organizations (ICAR, INTERBULL, EAAP). One of the most important outcome of these activities should result in a level of over 80% of the total population of cattle, pigs, sheep and other species of domestic farm animals in Serbia included in the control of production performance (presently between 25 and 30%). Genetic improvement of cattle, sheep and pigs (milk, meat) is very complex. More efficient use of reproductive technologies (AI - artificial insemination and embryo transfer ET, etc.), also of methods for evaluation of breeding value of farm animals through new methods of evaluation of breeding value of cows and breeding bulls will contribute to faster genetic improvement of production traits of these species of domestic animals. New knowledge in mapping and gene transfer, marker assisted selection, in vitro embryo development, embryo cloning, sexing, etc., are improving rapidly, with new technologies being developed permanently. Breeding/improvement of cattle, sheep and pigs in through breeding - selection work should facilitate further improvement of fertility traits, growth rate, feed efficiency, carcass quality (higher percentage of muscle tissue in the body), the quality of milk and meat, resistance to disease and stress, etc.
AB  - Početkom 2013. godine dobijeni su preliminarni rezultati popisa poljoprivrede u Republici Srbiji, obavljenog 2012. godine. Ukupan broj goveda je 908.990, svinja 3.403.288, ovaca 1.729.278 i koza 235.576 grla.. Povećanje konkurentnosti stočarstva Srbije se može ostvariti kreiranjem uslova za tržišno okruženje i putem investicija, kako u znanje, tako i u opremu. Zbog toga strukturne i institucionalne mere, kao i mere kreditne podrške treba da budu glavni instrumenti za ostvarenje ovog cilja. Aktivnosti u odgajivačko-selekcijskom radu treba da se sprovode u skladu sa preporukama međunarodnih organizacija (ICAR, INTERBULL, EAAP i druga). Jedan od najvažnijih rezultata ovog rada treba da prouzrokuje nivo od preko 80% ukupne populacije goveda, svinja, ovaca i ostalih vrsta domaćih životinja u Srbiji bude obuhvaćeno kontrolom proizvodnih svojstava (sada između 25 i 30%). Status i ciljevi oplemenjivanja goveda u Srbiji. Genetsko unapređenje goveda (mleko,meso) je vrlo kompleksno. Efikasnije korišćenje reproduktivnih tehnologija (VO-veštačko osemenjavanje i ET-embriotransfer i dr.) i korišćenje metoda za procenu odgajivačke vrednosti domaćih životinja preko novih metoda ocene priplodnih vrednosti bikova i krava će doprineti bržem genetskom unapređenju mlečnosti krava. Nova saznanja u mapiranju i transferu gena, selekciji preko markera, in vitro razvoju embriona, seksiranju i kloniranju embriona i dr. Odgajivački ciljevi-simentalska rasa, prosečna proizvodnja mleka u standardnoj laktaciji preko 6 000 kg; Holštajn frizijska rasa u standardnoj laktaciji preko 8 000 kg. Melezi iz ukrštanja domaćih krava nižih proizvodnih sposobnosti i bikova tovnih rasa, francuskih, italijanskih, engleskih. Odgajivački ciljevi ovakvog oplemenjivačkog rada i korišćenje heterozis efekta je stvaranje takvih genotipova koji će omogućiti završnu telesnu masu meleza F1, junadi od preko 550 kg, prosečni dnevni prirast u tovu preko 1500 g, randman toplih polutki preko 60%, sadržaj mišića u trupu od preko 65%. Status i ciljevi oplemenjivanja ovaca u Srbiji. Oplemenjivanje u cilju povećanja proizvodnje mesa treba da omogući dobijanje jagnjadi sa većim dnevnim prirastom (preko 300 g), veće završne mase tela sa 90 dana uzrasta (preko 28 kg), kao i većeg randmana trupa, više od 58%). Problem prelaska na policikličnost i oplodnju ovaca u toku cele godine obavio bi se na dva načina: genetički, korišćenjem ukrštanja rasa koje manifestuju estrus izvan normalne sezone (dorzet horn, il de france i romanovska) primenom metoda stimulacije, tj. indukcijom i sinhronizacijom estrusa.Tako bi se stvorili uslovi za primenu intenzivnog sistema jagnjenja dva jagnjenja u jednoj godini odnosno tri jagnjenja u dve godine. Sistem jagnjenja, sistem ukrštanja, selekcija i linijsko odgajivanje, zatim skraćenje post partum intervala i povećanje indeksa jagnjenja, kao i broja jagnjadi pri rođenju, rano zalučenje jagnjadi, korišćenje metode veštačkog osemenjavanja, automatskih mašina za dojenje, odgajivanje jagnjadi uspešnom zamenom za mleko i tov jagnjedi od 30 - 45 kg sa 90 do 120 dana. Status i ciljevi oplemenjivanja svinja u Srbiji. Oplemenjivanje svinja u cilju unapređenja mesnatosti preko odgajivačko-selekciojskog rada treba da omogući dalje poboljšanje osobina plodnosti, brzine porasta, iskorišćavanja hrane, kvaliteta trupa (veći procenat mišićnog tkiva u trupu), kvaliteta mesa i otpornosti svinja na bolesti i stres. Odgajivačko-selekcijskim radom neophodno je: povećati genetski potencijal postojećih mesnatih rasa i meleza svinja, raditi na stvaranju linija unutar čistih rasa primenom divergentne selekcije, kako bi se kasnije njihovim ukrštanjem ispoljivo veći heterozis efekat. Cilj selekcije treba da bude povećanje mišićnog tkiva u najvrednijim delovima trupa: but, plećka i kare. Odgajivački program u našoj zemlji predviđa ukrštanje landrasa (švedski, holandski,) i velikog jorkšira radi proizvodnje nazimica F1 generacije. One se posle toga ukrštaju sa nerastovima treće rase (terminalna rasa nerastova: hempšir, durok, pietren, nemački i belgijski landras) ili nerastovima F1 generacije.

Cilj selekcije treba da bude povećanje mišićnog tkiva u najvrednijim delovima trupa: but, plećka i kare. Odgajivački program u našoj zemlji predviđa ukrštanje landrasa (švedski, holandski,) i velikog jorkšira radi proizvodnje nazimica F1 generacije. One se posle toga ukrštaju sa nerastovima treće rase (terminalna rasa nerastova: hempšir, durok, pietren, nemački i belgijski landras) ili nerastovima F1 generacije.

AB  - The total number of potentially toxigenic molds (fungi), total aflatoxins, zearalenone (ZON), and deoxynivalenol (DON), as well as the joint appearance of ZON and DON have been investigated in 67 samples of cattle feed (concentrate (n=21), silage of whole maize plant (n=18), beet pulp (n=4), brewer's malt (n=2), alfalfa and grass (n=1), alfalfa hay (n=12), meadow hay (n=7), pea and oat hay (n=1), and red clover hay (n=1) originating from private farms from 10 districts of the Republic of Serbia. The total number of fungi per 1 g feed ranged from 0 (silage of brewer's malt) to 12 x 104 (concentrate). Eight fungi genus species have been identified: Acremonium, Alternaria, Aspergillus, Fusarium, Mucor, Penicillum, Rhizopus and Trichoderma. The presence of ZON (100%) was established in all the examined cattle feed samples, while 98.5% samples were contaminated with total aflatoxins and 92.5% samples were DON positive. The joint appearance of ZON and DON was established in 92.5% samples. ZON was present in the highest average concentration in the sample of alfalfa and grass silage (2477.5 μg kg-1) and in the lowest in beet pulp silage samples (64.9 μg kg-1). Total aflatoxins were established in the highest average concentration in the pea and oat hay silage sample (7.9 μg kg-1) and in the lowest average concentration in beet pulp silage samples (1.6 μg kg-1). DON was detected in the highest average concentration in concentrate samples (694.2 μg kg-1) and in the lowest average concentration in the red clover hay sample (11.0 μg kg-1), while DON was not detected in brewer's malt silage samples (0.0 μg kg-1). In all the examined cattle feed samples, between moisture content (up to 20%) and the concentration of examined mycotoxins, a negative correlation was established (r=-0.26) with total aflatoxins and a positive correlation with ZON (r=0,36) and DON (r=0,60). Furthermore, a positive correlation (r=0.22) was established between ZON and DON concentrations.
AB  - Ukupan broj potencijalno toksigenih gljivica (plesni), ukupni aflatoksini, zearalenon (ZON) i deoksinivalenol (DON) kao i združena pojava ZON i DON ispitivani su u 67 uzoraka hrane za goveda (koncentrat (n=21), silaža od cele biljke kukuruza (n=18), repinih rezanaca (n=4), pivskog trebera (n=2) i lucerke i trava (n=1), lucerkino seno (n=12), livadsko seno (n=7), seno od stočnog graška i ovsa (n=1) i seno od crvene deteline (n=1)) poreklom sa privatnih farmi iz 10 okruga u Republici Srbiji. Ukupan broj gljivica po 1 g hrane je bio od 0 (silaža od pivskog trebera) do 12 x 104 (koncentrat). Identifikovane su vrste iz osam rodova gljiva: Acremonium, Alternaria, Aspergillus, Fusarium, Mucor, Penicillum, Rhizopus i Trichoderma. U svim ispitivanim uzorcima hrane za goveda ustanovljeno je prisustvo ZON (100%), dok je 98,5% uzoraka bilo kontaminirano ukupnim aflatoksinima i 92,5% uzoraka je bilo DON pozitivno. Združena pojava ZON i DON ustanovljena je u 92,5% uzoraka. ZON je prisutan u najvećoj prosečnoj koncentraciji u uzorku silaže od lucerke i trava (2.477,5 μg kg-1), a u najmanjoj u uzorcima silaže od repinih rezanaca (64,9 μg kg-1). Ukupni aflatoksini su konstatovani u najvećoj prosečnoj koncentraciji u uzorku sena od stočnog graška i ovsa (7,9 μg kg-1), a u najmanjoj prosečnoj koncentraciji u uzorcima silaže od repinih rezanaca (1,6 μg kg-1). DON je detektovan u najvećoj prosečnoj koncentraciji u uzorcima koncentrata (694,2 μg kg-1), a u najmanjoj prosečnoj koncentraciji u uzorku sena od crvene deteline (11,0 μg kg-1), dok u uzorcima silaže od pivskog trebera DON nije detektovan (0,0 μg kg-1). U svim ispitivanim uzorcima hrane za goveda između sadržaja vlage (do 20%) i koncentracija ispitivanih mikotoksina ustanovljena je negativna korelacija (r=-0,26) sa ukupnim aflatoksinima i pozitivna korelacija sa ZON (r=0,36) i DON (r=0,60). Isto tako, pozitivna korelacija (r=0,22) ustanovljena je između koncentracija ZON i DON.

AB  - It is general knowledge that management influences results in cattle production to the highest extent, and that the culling of cows is a very good indicator of the success of farm management. A comparison of results of culling for first calving cows on farms with various levels of production in 2011 established differences both for the number of culled animals and the reasons for culling. On farms with higher levels of production, the share of first calving cows in overall culling was 25.9% or 4.5% less than on farms with a lower level of production, i.e. 4.8% less died, and 0.7% first calving cows had to be slaughtered, while 5.6% more first calving cows were culled for economic reasons. At both levels of production, dominant reasons for culling were diseases of the legs and hoofs, which can be linked to the tie stall system (more pronounced on farms with higher production) and metabolic disorders (more dominant on farms with lower production). Reproduction was a more considerable problem on farms with higher milk production, while culling due to selection was more pronounced on farms with lower production. In early lactation of first calving cows, regardless of the level of production, dominant reasons for culling on farms are leg and hoof problems and metabolic disorders (total: 55% i.e. 55.9%). When reasons for culling of first calving cows after 100 days of lactation are investigated, on farms with high production the significance of diseases of legs and hoofs remains almost unchanged, but culling due to reproduction grows to 28%. On farms with lower production, culling due to leg and hoof diseases is considerably reduced after 100 days of lactation, however culling due to selection is tripled (62%).
AB  - Opšte je poznato da menadžment u najvećoj meri utiče na rezultate u govedarskoj proizvodnji, a izlučenja krava su vrlo kvalitetan pokazatelj uspešnosti upravljanja farmama. Poredeći rezultate izlučenja prvotelki na farmama sa različitim nivoom proizvodnje u toku 2011. god. ustanovljene su razlike i u broju izlučenih grla, ali i u razlozima izlučenja. Na farmama sa višim nivoom proizvodnje učešće prvotelki u ukupnim izlučenjima bilo je 25.9% što je za 4.5% manje nego na farmama sa nižim nivoom proizvodnje, odnosno uginulo je za 4,8% manje i prinudno je zaklano za 0,7% manje prvotelki, a iz ekonomskih razloga izlučeno za 5.6% prvotelki više. Na oba nivoa proizvodnje dominantni razlozi izlučenja su bili oboljenja nogu i papaka što se može dovesti u vezu sa vezanim sistemom držanja (izraženije na farmama sa većom proizvodnjom) i metabolički poremećaji (dominantnije izraženi na farmama sa nižom proizvodnjom). Reprodukcija je bila znatniji problem na farmama sa većom proizvodnjom mleka, odnosno selekcijska izlučenja na farmama sa nižom proizvodnjom. U ranoj laktaciji prvotelki, bez obzira na nivo proizvodnje, na farmama kao razlozi izlučenja dominiraju problemi sa nogama i papcima i metabolički poremečaji (ukupno 55% tj. 55.9%). Kada se posmatraju razlozi izlučenja prvotelki nakon 100 dana laktacije, na farmama sa visokom proizvodnjom značaj obolenja nogu i papaka je gotovo nepromenjen, ali izlučenja usled reprodukcije rastu na 28%. Na farmama sa nižom proizvodnjom, izlučenja usled oboljenja nogu i papaka su znatno smanjena nakon 100 dana laktacije, ali je zato utrostručen broj izlučenih iz selekcijskih razloga (62%).

SEUROP standard je koncipiran da omogući 'zajednički EU jezik' koji opisuje kvalitet junećih trupova kao i analitiku baze podataka o životinjama, rezultatima klasifikacije i cenama što je od velikog značaja za primenu različitih mera podrške na tržištu unije. Obzirom da ovaj sistem podržava isplatu odgajivačima prema kvalitetu trupova, ovo je i važan instrument kojim se podstiče rad na unapređenju genotipova, ishrane i tehnologije u govedarstvu. U radu je dat pregled najvažnijih zakonskih regulativa i osnovnih parametara SEUROP klasifikacije junećeg mesa u smislu definicije, prezentacije i kategorizacije trupa kao i kriterijuma u oceni konformacije i prekrivenosti trupa lojem.",

AB  - Objective of the research was to investigate the level, structure and variability of realized differences between average values of body condition scores in high-yielding cows during most critical phases of production cycle. Realized differences were used as criterion for assessment of changes occurring in the cows' energy status through the level of increase or decrease of body condition. Realized average values of body condition scores, for individual and all body regions, within all studied phases of production cycle, deviated statistically very significantly (p≤0,01) from target values. Differences between average values of body condition scores according to phases of production cycle, for individual and all body regions, were statistically very significant (p≤0,01). Optimum body condition in dry period was realized by 48,76% cows, at calving 53,61%, in the lactation peak 24,41% and in mid lactation 21,12%. Average value of body condition scores at calving was higher by 0,18 (-0,01 to 0,72) units compared to beginning of dry period, whereas at the lactation peak it was by -1,26 (-2,75 to - 0,41) units lower compared to calving, and in mid lactation compared to lactation peak it was higher by 0,18 (-0,94 to 0,85) units. Within the distribution of achieved differences in body condition scores in the time from the beginning of dry period to calving in 346 cows or 96,11% of total number of animals (n=360) increase of body condition score was realized ranging from ≤ 0,25 units. Distribution of differences in body condition scores between calving and lactation peak showed that 243 cows or 71,48% of total 340 cows realized loss of body condition score of >1,00 units. Within distribution of differences in body condition scores between the lactation peak and mid lactation, 261 cows or 81,06% of total number of scored animals (n=322) increased the body condition score in value of ≤ 0,25 units. Study showed that, except in the dry period, changes of the body condition during other phases of production cycle weren't within the limits of optimum values. Realized results clearly showed the possibility of incidence of various production disorders, health issues and reproduction problems. Consequences are reflected also on longevity, life production and genetic progress. Realized differences in average values of body condition scores were important basis for anticipation of potential problems. In that regard, there are significant reserves in improvement of efficiency of management of body energy reserves in high yielding cows.

AB  - In this study, the effects of the organic and inorganic form of selenium, in the diet for finishing beef cattle, were investigated. Sell-Plex produced by American firm Alltech as a source of organic selenium with selenium concentration of 2000 mg/kg was used. The source of inorganic selenium was sodium selenite. The trial was conducted on Simmental fattening cattle in the final stage in the free housing system and it lasted 60 days. Selenium content in control and trial group (m. longissimus dorsi) was 78.65 and 125.03 μg/kg (P (lt) 0.01), in kidneys 855.52 and 1026.04 μg/kg(P  (lt) 0.001); in liver 453.13 and 534.64 μg/ kg(P (lt) 0.01) and in spleen 308.44 and 383.62 μg/kg (P (lt) 0.001), respectively. There were no differences in main carcass characteristics, share of some tissues in the round and three rib chops, chemical composition and meat quality of m. longissimus dorsi (P>0.05).Considering the higher storage of organic selenium in meat and internal organs of the fattening cattle with respect to the inorganic form, it was concluded that the selenium supply in organic form has a better bioavailability. Inclusion of organic selenium into the diet in the final stage of fattening cattle and its deposition in meat and internal organs is a good and easy way to get meat with functional foods properties that in addition to nutritional value should positively affect human health.
AB  - U radu su ispitani efekti organskog i neorganskog selena u obrocima junadi u tovu.

Ogled je izveden na Simentalskoj rasi goveda u završnoj fazi tova u slobodnom sistemu držanja i trajao je 60 dana. Sadržaj selena u m. longissimus dorsi, jetri, slezini i bubrezima bio je značajno viši na ishranbenom tretmanu sa organskim selenom u odnosu na neorganski, što ukazuje na njegovu bolju bioiskoristivost. Urađena je disekcija polutke prema zvanično važećoj skali za klasifikaciju trupova odraslih goveda propisanoj od strane evropske zajednice. Dobijeni rezultati ukazuju da nije bilo razlike između tretmana sa organskim i neorganskim selenom u telesnoj masi grla pre klanja kao i glavnim karakteristikama polutke. Takođe, nije bilo razlike u udelu pojedinih tkiva u butu i trorebarnom isečku kao i ni u hemijskom sastavu i kvalitetu mesa u m. longissimus dorsi. Imajući u vidu da je selen esencijalan mikroelement u ishrani a da organski vezan selen ima bolju bioiskoristivost u odnosu na neorganski, njegovo uključivanje u obroke goveda i deponovanje u mesu i unutrašnjim organima je dobar i jednostavan način za dobijanje mesa sa svojstvima funkcionalne hrane koja treba da pored nutritivne vrednosti pozitivno utiče na zdravlje ljudi. Pošto su pojedini delovi planete Zemlje slabo opskrbljeni sa selenom ovo je najjednostavniji način da se reši problem njegovog deficita.

AB  - The aim of the study was, within the tested samples of high yielding Holstein-Friesian cows (n = 363), to analyze the significance of the actual level of correlation between the average BCS of cows according to body regions and results in the production of milk indifferent stages and the standard duration of lactation. Differences in average realized BCS in regard to the recommended values in stages of production cycle were highly significant (p ≤ 0.01). In general, realized correlation coefficients, whose significance was tested, were at very low level. The average value of the BCS at dry off period in the first, second and third body region was statistically significantly (p  (lt) 0.05) and highly significantly (p  (lt) 0.01) positively associated with milk production during the first 100 days of lactation. The mean value of BCS at dry off period in the second body region was in a statistically significant positive correlation (p  (lt) 0.05) with the production of milk in the second 100 days and standard lactation. The average value of BCS at dry off period for all three body regions was highly significantly (p  (lt) 0.05) positively associated with milk production in the first 100 days. The mean value of BCS at calving in the first body region was highly significantly (p  (lt) 0.01) positively associated with milk production during the first and the second 100 days of lactation and standard lactation. Average BCS value at calving for the second body region was highly significantly (p  (lt) 0.01) positively correlated with milk production in the first and second 100 days of lactation and significantly positvely correlated (p  (lt) 0.05) with the production of milk in the standard lactation. The mean value of BCS at calving in the third body region was highly significantly (p  (lt) 0.01) positively correlated with milk production during the first 100 days of lactation and significantly positively correlated (p  (lt) 0.05) with the production of milk in the second 100 days and standard lactation. Average BCS value for all three body regions at calving was in a highly significant (p  (lt) 0.01) positive correlation with milk production in the first hundred days of lactation. A significant positive correlation (p  (lt) 0.05) with the production of milk in the second 100 days and a standard lactation was achieved. The average value of BCS at the peak of lactation for the first, second and third body region was significantly (p (lt) 0.05) and highly significantly (p (lt) 0.01) negatively correlated with the production of milk in a standard lactation. The mean value of BCS at the peak of lactation for all three body regions was very significantly (p  (lt) 0.01) negatively correlated with the production of milk in the standard lactation. The mean value of BCS in the mid-lactation for the first, second and third body region was highly significantly (p  (lt) 0.01) negatively correlated with the production of milk in the standard lactation. BCS average value for all three body regions in the mid-lactation was very significantly (p  (lt) 0.01) negatively correlated with the production of milk in the standard lactation.
AB  - Cilj istraživanja bio je da se u okviru ispitivanog uzorka visokomlečnih krava holštajn-frizijske rase (n=363) analizira značajnost ostvarenog nivoa povezanosti između prosečnih vrednosti BCS krava po telesnim regijama i postignutih rezultata u proizvodnji mleka po fazama i standardnom trajanju laktacije. Razlike ostvarenih prosečnih BCS u odnosu na preporučene optimalne vrednosti po fazama proizvodnog ciklusa su visoko značajne (p≤0.01). U celini posmatrano realizovani koeficijenti korelacije, čija je značajnost ispitana, bili su na niskom nivou. Prosečna vrednost BCS na zasušenju u prvoj, drugoj i trećoj telesnoj regiji bila je statistički značajno (p (lt) 0.05) i vrlo značajno (p (lt) 0.01) pozitivno povezana sa proizvodnjom mleka u prvih 100 dana laktacije. Srednja vrednost BCS na zasušenju u drugoj telesnoj regiji bila je u statistički značajnoj pozitivnoj vezi (p (lt) 0.05) sa proizvodnjom mleka u drugih 100 dana i standardnoj laktaciji.

abstract = "The aim of the study was, within the tested samples of high yielding Holstein-Friesian cows (n = 363), to analyze the significance of the actual level of correlation between the average BCS of cows according to body regions and results in the production of milk indifferent stages and the standard duration of lactation. Differences in average realized BCS in regard to the recommended values in stages of production cycle were highly significant (p ≤ 0.01). In general, realized correlation coefficients, whose significance was tested, were at very low level. The average value of the BCS at dry off period in the first, second and third body region was statistically significantly (p  (lt) 0.05) and highly significantly (p  (lt) 0.01) positively associated with milk production during the first 100 days of lactation. The mean value of BCS at dry off period in the second body region was in a statistically significant positive correlation (p  (lt) 0.05) with the production of milk in the second 100 days and standard lactation. The average value of BCS at dry off period for all three body regions was highly significantly (p  (lt) 0.05) positively associated with milk production in the first 100 days. The mean value of BCS at calving in the first body region was highly significantly (p  (lt) 0.01) positively associated with milk production during the first and the second 100 days of lactation and standard lactation. Average BCS value at calving for the second body region was highly significantly (p  (lt) 0.01) positively correlated with milk production in the first and second 100 days of lactation and significantly positvely correlated (p  (lt) 0.05) with the production of milk in the standard lactation. The mean value of BCS at calving in the third body region was highly significantly (p  (lt) 0.01) positively correlated with milk production during the first 100 days of lactation and significantly positively correlated (p  (lt) 0.05) with the production of milk in the second 100 days and standard lactation. Average BCS value for all three body regions at calving was in a highly significant (p  (lt) 0.01) positive correlation with milk production in the first hundred days of lactation. A significant positive correlation (p  (lt) 0.05) with the production of milk in the second 100 days and a standard lactation was achieved. The average value of BCS at the peak of lactation for the first, second and third body region was significantly (p (lt) 0.05) and highly significantly (p (lt) 0.01) negatively correlated with the production of milk in a standard lactation. The mean value of BCS at the peak of lactation for all three body regions was very significantly (p  (lt) 0.01) negatively correlated with the production of milk in the standard lactation. The mean value of BCS in the mid-lactation for the first, second and third body region was highly significantly (p  (lt) 0.01) negatively correlated with the production of milk in the standard lactation. BCS average value for all three body regions in the mid-lactation was very significantly (p  (lt) 0.01) negatively correlated with the production of milk in the standard lactation., Cilj istraživanja bio je da se u okviru ispitivanog uzorka visokomlečnih krava holštajn-frizijske rase (n=363) analizira značajnost ostvarenog nivoa povezanosti između prosečnih vrednosti BCS krava po telesnim regijama i postignutih rezultata u proizvodnji mleka po fazama i standardnom trajanju laktacije. Razlike ostvarenih prosečnih BCS u odnosu na preporučene optimalne vrednosti po fazama proizvodnog ciklusa su visoko značajne (p≤0.01). U celini posmatrano realizovani koeficijenti korelacije, čija je značajnost ispitana, bili su na niskom nivou.

AB  - This paper presents the results reflected on obtaining the milk enriched with omega-3 fatty acids. As source of omega-3 fatty acids, product of French company Vitalac called "TradiLin", was used. Trial was carried out on 20 trials (T) and 20 control (C) cows of Simmental breed and it lasted 80 days. Average content of omega-3 in trial and control group was 0.586 and 0.284 g/100g of extracted fat (P≤0.01), whereas content of omega-6 in same order of treatments was 3.141 and 3.011 g/100g of extracted fat (P≤0.05). Ratio omega-6/omega-3 fatty acids of 10.602 (control) was declined to 5.360 (trial), which is considered to be desirable from the aspect of nutrition with milk as functional food. Also, in other milk final product called "mladi kajmak", obtained by taking off milk fat from the surface of heat treated and cooled milk, content of omega-3 in trial and control group showed the same trend, 0.76 and 0.41 g/100g of extracted fat (P≤0.01), whereas content of omega-6 were 3.90 and 3.79 g/100g of extracted fat (P≤0.05). Ratio omega-6/omega-3 in control group was reduced of 9.24 to 5.10, which are considered to be extremely favourable. Chemical constituents of milk, somatic cell count as well as total plate count showed no differences between groups (P>0.05). Also, investigated treatment had no effect on changes in biochemical blood parameters.

AB  - Cattle production in Serbia, and especially milk production, contributes significantly to the value of total agricultural production (20%) and livestock production (45%). Achieved annual rate of milk yield increase of approx.100 kg per cow cannot adequately compensate for drastic decrease of number of dairy cattle which dropped by fifth over last decade. This is especially important from the aspect of assessment of future production quotas for milk as part of Serbia's preparation for EU accession. From the aspect of the genetic potential of dairy cattle, the most significant measure aimed at increase of milk performance in future will be execution of systematic selection-breeding work in the main population. Special attention should be directed in future to selection of parents of dairy herd, criteria for selection of heifers and their adequate rearing in sense of nutrition and housing. For the purpose of establishing of production potential of first calving Simmental cows in Serbia, data was analyzed for 37.171 Simmental cows with completed lactations in the period 2007 to 2010. Research results showed moderate trend of increase in milk performance in first calving cows - average milk production of 4.348 kg, milk fat content of 3.93% and milk fat yield of 171.1 kg. Milk performance of first calving cows in average was lower by 147 kg compared to cows in other lactations and by 1.169 kg compared to bull dams in the observed period. In analysis of bulls - most common sires of studied first-calvers, it was established that eight of ten bull sires had negative values for milk yield, which indicated the need for better cooperation and organization in work of all services which are included in selection-breeding activities in dairy cattle breeding.
AB  - Govedarstvo Srbije a posebno proizvodnja mleka značajno učestvuju u vrednosti ukupne poljoprivredne (20%) i stočarske proizvodnje (45%). Postignutim tempom rasta prinosa mleka od oko 100 kg po kravi godišnje ne može se adekvatno kompenzovati drastičan pad broja mlečnih grla koji je u protekloj deceniji opao za petinu. Ovo je posebno značajno sa aspekta procena budućih proizvodnih kvota za mleko u priprema Srbije za ulazak u EU. Sa aspekta genetskog potencijala mlečnih krava, najznačajnija mera za povećanja prinosa mleka u narednom periodu je sprovođenje sistematskog odgajivačko-selekcijskog rada u matičnoj populaciji. Izboru roditeljskih parova budućih generacija mlečnog stada, kriterijumima odabira junica i njihovom pravilnom odgoju u smislu ishrane i uslova držanja treba posvetiti primaran značaj.

AB  - The subject of this research was to determine the effect of the housing system on quality of welfare of dairy cattle in Serbia. Study was realized on six farms, capacity of 30 to 900 cows, with loose and tie housing system. Assessment of the welfare quality parameters was done by using the Welfare Quality® Assessment Protocol for Cattle, 2009. Results of the research show that the welfare quality of dairy animals is under the significant effect of housing system, and that loose system has the advantage when it comes to comfort around resting, easy of movements and health condition of cows. Share of not lame cows (81%) and cows with no lesion (86%) was significantly higher (p (lt) 0.01) in loose system. Indicator values: duration of lying down movements (6.53 sec), lying down movements with collisions (18.7%) and lying outside lying area (28.4%) in tie system were significantly higher (p (lt) 0.01) compared to loose system indicating the inadequacy of the housing and lack of comfort. Analysis of indicators associated with cow hygiene (dirty legs and udder) and diseases (dystocia) points to significant gaps in management in both housing systems which represent significant threat to cow welfare quality.
AB  - Predmet ovog istraživanja bilo je utvrđivanje uticaja sistema držanja na kvalitet dobrobiti mlečnih krava u Srbiji. Ispitivanje je obavljeno na šest farmi, kapaciteta od 30 do 900 krava, sa slobodnim i vezanim sistemom držanja. Ocena parametara kvaliteta dobrobiti obavljena je korišćenjem Welfare Quality® Assesment Protocol for Cattle, 2009. Rezultati istraživanja pokazuju da se kvalitet dobrobiti mlečnih krava nalazi pod značajnim uticajem sistema držanja kao i da slobodni sistem ima prednost kada su u pitanju udobnost/komfor tokom /ležanja, lakoća kretanja i zdravstveno stanje krava.

abstract = "The subject of this research was to determine the effect of the housing system on quality of welfare of dairy cattle in Serbia. Study was realized on six farms, capacity of 30 to 900 cows, with loose and tie housing system. Assessment of the welfare quality parameters was done by using the Welfare Quality® Assessment Protocol for Cattle, 2009. Results of the research show that the welfare quality of dairy animals is under the significant effect of housing system, and that loose system has the advantage when it comes to comfort around resting, easy of movements and health condition of cows. Share of not lame cows (81%) and cows with no lesion (86%) was significantly higher (p (lt) 0.01) in loose system. Indicator values: duration of lying down movements (6.53 sec), lying down movements with collisions (18.7%) and lying outside lying area (28.4%) in tie system were significantly higher (p (lt) 0.01) compared to loose system indicating the inadequacy of the housing and lack of comfort. Analysis of indicators associated with cow hygiene (dirty legs and udder) and diseases (dystocia) points to significant gaps in management in both housing systems which represent significant threat to cow welfare quality., Predmet ovog istraživanja bilo je utvrđivanje uticaja sistema držanja na kvalitet dobrobiti mlečnih krava u Srbiji. Ispitivanje je obavljeno na šest farmi, kapaciteta od 30 do 900 krava, sa slobodnim i vezanim sistemom držanja. Ocena parametara kvaliteta dobrobiti obavljena je korišćenjem Welfare Quality® Assesment Protocol for Cattle, 2009. Rezultati istraživanja pokazuju da se kvalitet dobrobiti mlečnih krava nalazi pod značajnim uticajem sistema držanja kao i da slobodni sistem ima prednost kada su u pitanju udobnost/komfor tokom /ležanja, lakoća kretanja i zdravstveno stanje krava. Udeo krava bez znakova šepavosti (81%) i krava bez lezija/povreda (86%) bio je signifikantno veći (p (lt) 0.01) u slobodnom sistemu.

AB  - Possibilities for improvement of the quality of beef in population of Domestic spotted cattle breed (D) by application of industrial crossing with French fattening breeds Charolais (DxS) and Limousine (DxL) were investigated. Comparative research included 25 heads of young cattle of DxS, 18 crosses of DxL and 21 crosses of D genotype. Results of the analysis of chemical composition of longissimus muscle in young cattle show significant statistical differences (P (lt) 0.05) in percentage of intramuscular fat, the highest value was determined in cattle of group DxS (2.37%), and in total pigments which was the highest in cattle of group D (101.12 ppm). Young cattle in group D had the lowest value of the meat shear force after heat treatment (5.43 kg/cm2), i.e. they had the tenderest meat. Data obtained in the sensory analysis of cooked meat were very high and showed no significant differences between groups. Statistically significant difference (P (lt) 0.05) was established only in assessment of aroma/taste, which was somewhat higher in young cattle of group DxS (4.87). Data obtained in this trial justify the economic goal of crossing of domestic Simmental breed with noble cattle breeds in production of meat of high quality, which is of great importance both for producers (farmers) and final customer (consumer).

AB  - In this study the effects of 'Tradi-Lin' as a source of omega-3 fatty acids (FA) in diets for fattening cattle were presented. 'Tradi-Lin' produced from flax seed had 58% omega-3 and 15% omega-6 fatty acids of total polyunsaturated fatty acids (PUFA). Trial was carried out on three groups of finishing beef cattle (C, T1 and T2) with 15 heads in each and was lasted 60 days. The diets used based on maize silage and concentrate mixture. Cattle received 0, 300 and 700 g of 'Tradi-Lin' per day, respectively. At the end of trial heads were slaughtered and major parameters of the chemical composition and meat quality were determined. The results indicated that were no differences in saturated (50.85; 50.21; 50.34%) and unsaturated (49.15; 49.79; 49.66%) FA between treatments in intramuscular fat of the m. longissimus dorsi but 'Tradi-Lin' influenced the changes in structure of intramuscular fat and increased PUFA from 4.91 (C) to 5.54 (T1) and 7.31% (T2) ( P (lt)  0.05). The increase of omega-3 FA from 0.36 (C) to 0.60 (T1) and 0.76% (T2) must be pointed out, ( P (lt)  0.05). The omega-6 FA were also increased from 4.51 (C) to 4.94 (T1) and 6.22% (T2) (P>0.05) but omega-6: omega- 3 ratio was reduced from 12.25 (C) to 8.22 (T1) (P (lt)  0.05) and 8.62(T2), (P (lt) 0.01). Trans unsaturated FA which are undesirable were decreased from 3.37% (C) to 2.43% (T1) and 2.36% (T2)(P (lt) 0.05). From nutritional aspect those results have a great importance, having in mind that omega-3 FA have a vital role in human health.
AB  - U radu su predstavljeni efekti korišćenja proizvoda 'Tradi-Lin' kao izvora omega-3 masnih kiselina u obrocima junadi u tovu. Proizvod 'TradiLin'dobijen je termičkom obradom semena lana, sadrži 58% omega-3 i 15% omega-6 masnih kiselina od ukupno polinezasićenih masnih kiselina (PUFA) i predstavlja patent francuske firme Vitalac. Ogled je izveden na tri grupe simentalske rase junadi (C, T1 i T2) sa po 15 grla u svakoj, u periodu dva meseca pred klanje. Obroci za sve grupe junadi bili su potpuno identični i bazirani na silaži cele biljke kukuruza i smeši koncentrata. Jedina razlika bila je ta što su grla pored osnovnog obroka dobijala 0, 300 i 700 g 'Tradi-Lin' -a dnevno, respektivno. Na kraju ogleda grla su zaklana i određeni su najvažniji parametri hemijskog sastava i kvaliteta mesa. Dobijeni rezultati ukazuju da u intramuskularnoj masti leđnog dela M. longissimus dorsi (MLD) nije postojala razlika u sadržaju zasićenih (50,89; 50,21; 50,32%) i nezasićenih (49,15; 49,79; 49,66%) masnih kiselina među ispitivanim tretmanima (C, T1 i T2). Međutim, dodavanje 'TradiLin'- a uticalo je na promenu strukture intramuskularne masti u korist povećanja PUFA od 4,95 (C), na 5,98 (T1) odnosno 7,31% (T2) (P (lt) 0.05). Treba posebno istaći povećanje sadržaja omega-3 masnih kiselina sa 0,36 (C) na 0,60 (T1) odnosno na 0,76% (T2), (P (lt)  0,05). Jednovremeno povećao se sadržaj omega-6 masnih kiselina od 4,51 (C) na 4,94 (T1) odnosno 6,22% (T2) (P>0,05) a odnos omega -6/omega-3 smanjen sa 12,25 (C) na 8,22 (T1) (P (lt) 0,05) i 8,62 (T2), (P  (lt) 0,01). Sadržaj trans nezasićenih masnih kiselina koje su nepoželjne smanjen je sa 3,37% (C) na 2,43% (T1) (P (lt) 0,05) odnosno 2,36% (T2). Dodavanje 0,7 kg ovog preparata u obroke u zadnjih dva meseca tova potpuno je ekonomski opravdano jer utiče na zanemarljivo povećanje cene u odnosu efekte koji se dobijaju. Sa nutricionističkog aspekta ovi rezultati imaju veliki značaj imajući u vidu da omega-3 masne kiseline imaju vitalnu ulogu u očuvanju zdravlja ljudi.

AB  - The present situation in livestock production and production of meat is presented in this paper, as well as directions for future work aimed at bringing changes to this branch of economy. In the last decade, a drop in the number of animals was recorded of approx. 2 to 3% at annual level. Also, drop in production of meat was recorded from 444.000 tons (1990) to 384.000 tons (2010). In order to have planned progress in production of meat it is necessary to define more clearly breeding goals with precise determination of all economically relevant and indicator traits. In addition to growth and body development traits which have so far been in focus of selection work, for production of meat also maternal traits are important, food conversion and quantity and quality traits of carcasses and meat.
AB  - Dugoročna koncepcija razvoja stočarstva treba da se temelji na efikasnosti proizvodnje mesa, preko organizovanja farmera. Za uspešno organizaciono i ekonomsko jačanje farmera važan je pravilan izbor poslovnog povezivanja. Za brdsko planinska područja naše zemlje, u kojima nema organizovanih otkupnih i prerađivačkih kapaciteta i koja su udaljena od gradskih centara, veoma interesantan oblik povezivanja će biti formiranje novih malih preradnih kapaciteta. Stabilne i unapred poznate cene za proizvode stočarstva, kao i dobro postavljeni pariteti cena garancija su za stabilno stočarstvo. Naša dosadašnja iskustva u unapređenju stočarstva i ostvareni rezultati u svetu, transfer tehnologija, sve više nas upućuju da je za brže ukupno poboljšanje stočarstva neophodna bolje organizovana i pojačana stručna i naučna infrastruktura. U Srbiji je 2010-godine i pored manjeg broja stoke proizvedeno ukupno 384.000 tona junećeg, svinjskog i jagnjećeg mesa, što je za 3,3% više nego u 2009. godini, odnosno 6,3 odsto više nego što je bila prosečna proizvodnja od 2001. do 2009. godine. U Srbiji u 2010. bila manja proizvodnja goveđeg, junećeg i telećeg mesa za 4,4 odsto i ovčijeg i jagnjećeg mesa za 7,1 odsto, dok se za 6,8 odsto više proizvodilo svinjsko. 2010-godine, u poređenju sa prosečno ostvarenom proizvodnjom u periodu od 2001. do 2009. proizvedeno je više svih vrsta mesa: svinjskog mesa za 3,1%, goveđeg i junećeg mesa za 7,5, i ovčijeg i jagnjećeg mesa za 15%. Sva domaćinstva koja se ozbiljnije bave govedarskom proizvodnjom trebalo bi u narednom periodu organizovati kao gazdinstva za tržišnu proizvodnju mleka, gazdinstva za tržišnu proizvodnju tovne junadi i gazdinstva za kombinovanu tržišnu proizvodnju mleka i junadi za klanje. Osnovnu pažnju u programima razvoja ovčarstva treba posvetiti porodičnom gazdinstvu i novim tehnologijama koje se bave intenziviranjem proizvodnje mesa, mleka i vune na farmama ovaca. Specijalizovani farmeri za meso, odnosno mleko treba da poseduju od 100-500 grla ovaca, kao i odgovarajuću infrastrukturu. Farmeri trojnog smera proizvodnje su tradicionalna domaćinstva koja drže do 20 ili 50 ovaca. Njima treba obezbediti kvalitetan priplodni materijal i svaku drugu pomoć u cilju povećanja njihove proizvodnje. Porodične farme bi u narednom desetogodišnjem periodu trebale da drže 50 a zatim do 100 krmača i tove 1000 i više tovljenika. Sve to bi moglo dovesti do povećanja proizvodnje svinjskog mesa po prosečnoj godišnjoj stopi od 2 do 2,5%. Neophodno je odabrati najbolje farme kako bi se formirali elitni, umnožavajući (reproduktivni) i proizvodni (komercijalni) zapati u piramidalnoj organizaciji proizvodnje priplodnih grla i tovljenika.

abstract = "The present situation in livestock production and production of meat is presented in this paper, as well as directions for future work aimed at bringing changes to this branch of economy. In the last decade, a drop in the number of animals was recorded of approx. 2 to 3% at annual level. Also, drop in production of meat was recorded from 444.000 tons (1990) to 384.000 tons (2010). In order to have planned progress in production of meat it is necessary to define more clearly breeding goals with precise determination of all economically relevant and indicator traits. In addition to growth and body development traits which have so far been in focus of selection work, for production of meat also maternal traits are important, food conversion and quantity and quality traits of carcasses and meat., Dugoročna koncepcija razvoja stočarstva treba da se temelji na efikasnosti proizvodnje mesa, preko organizovanja farmera. Za uspešno organizaciono i ekonomsko jačanje farmera važan je pravilan izbor poslovnog povezivanja. Za brdsko planinska područja naše zemlje, u kojima nema organizovanih otkupnih i prerađivačkih kapaciteta i koja su udaljena od gradskih centara, veoma interesantan oblik povezivanja će biti formiranje novih malih preradnih kapaciteta. Stabilne i unapred poznate cene za proizvode stočarstva, kao i dobro postavljeni pariteti cena garancija su za stabilno stočarstvo. Naša dosadašnja iskustva u unapređenju stočarstva i ostvareni rezultati u svetu, transfer tehnologija, sve više nas upućuju da je za brže ukupno poboljšanje stočarstva neophodna bolje organizovana i pojačana stručna i naučna infrastruktura.

AB  - Black and White low land dairy cattle have very pronounced ability for high production of milk. Fertility is the major trait of cattle and key factor in successful milk production. Fertility traits have pronounced variability and low heritability value. Fertility is regularly limiting factor in attempts to increase the milk yield. Age of dairy cattle at first conception is one of the major reproduction properties. Age of calves at first calving depends mainly on age at first conception. Previous researches have indicated what would be the optimum age at first conception of Black and White heifers. Age at first conception is determined by the date of birth and date of first conception. Knowledge of the strength of the environment factors on age at first conception in high yielding cows is important from the aspect of their inclusion into the model. According to the significance of individual systematic factors, their objective assessment was carried out for the purpose of accurate evaluation of obtained results. Objective of this paper is to study the age at first conception of high yielding Black and white cows through major systematic influences, by applying adequate methodology. Cows comprising the studied sample (n=331) belong to European type of Black and White dairy cattle in final stage of improving of this breed with Holstein-Friesian breed. Average age of dairy cattle at first conception was 491.19±9.36 days or 16.15±0.31 months. According to cows' the values were following: 479.31 days (> 73% HF), 486.12 days (58-73%HF) and 508.14 days ( (lt)  58% HF).
AB  - Osobine plodnosti imaju izuzetno veliki ekonomski značaj koji se ispoljava kroz normalan tok proizvodnog ciklusa. Jedna od njihovih vrlo važnih specifičnosti je veoma izražena varijabilnost i niska naslednost. Uzrast grla kod prve oplodnje/teljenja je važna osobina plodnosti goveda. Crno-bela nizijska goveda imaju izraženu genetsku sposobnost za visoku proizvodnju mleka. Visokoproizvodne krave crno-bele rase izložene su tokom produktivnog veka velikom broju složenih uticaja. Uslovi proizvodnje vrlo često nisu u saglasnosti sa visokim potrebama ove rase. Problemi u reprodukciji često predstavljaju ograničavajući faktor za povećanje proizvodnje mleka. Unošenjem gena holštajn-frizijske rase u okviru programa oplemenjivanja evropskih crno-belih goveda došlo je do tendencije povećanja prinosa mleka i smanjenja plodnosti. Dosadašnja istraživanja ukazuju na prihvatljiv uzrast pri prvoj oplodnji kod junica crno-bele rase. Poznavanje jačine uticaja sredine na uzrast pri prvoj oplodnji kod visokomlečnih krava važno zbog njihovog uključivanja u model. U skladu sa pojedinačnim značajem sistematskih faktora, obavljena je njihova objektivna procena radi što tačnijeg vrednovanja ostvarenih rezultata. Cilj ovog rada je bio da se primenom odgovarajuće metodologije ispita uzrast kod prve oplodnje visokomlečnih crno-belih krava preko najvažnijih sistematskih uticaja. Krave u okviru ispitanog uzorka (n=331) pripadaju evropskim crno-belim nizijskim govedima u završnoj fazi oplemenjivanja holštajn-frizijskom rasom. Prosečna starost grla pri prvoj oplodnji iznosila je 491.19±9.36 dana ili 16.15±0.31 meseci. Posmatrano po genotipovima krava iznosio je 479.31 dana (> 73%HF), 486.12 dana (58-73%HF) i 508.14 dana ( (lt)  58%HF). Na utvrđene razlike u pogledu uzrasta pri prvoj oplodnji značajan uticaj (p≤0.05) pokazali su bikoviočevi, klasa HF gena krava nije imala značajan uticaj (p>0.05), godina teljenja pokazala je visoko značajan uticaj (p≤0.01), dok je sezona teljenja ispoljila značajan uticaj (p≤0.05).

AB  - For the purpose of investigation of factors important for slaughter yield results, a trial with three groups of young cattle of Domestic Simmental breed of different body masses was carried out. Young cattle in the first group (G1) (n=6) had average body mass of 509,00 kg (475-525), in the second group (G2) of young cattle (n=7) average body mass of 554,29 kg (530 - 575) was recorded and in the third group of young cattle (G3) (n=8) 591,13kg (580-615). Subsequent to slaughtering warm carcass sides were measured individually, with and without kidney fat, mass of internal organs was measured (kidneys, liver, lungs, heart, spleen) and mass of other secondary slaughter products (head, tongue, tail, muscle part of diaphragm). After cooling carcass sides were cut into main parts. Based on obtained results of research it was established that male cattle of group (G2) of Domestic Simmental breed of average body mass of 554,29 kg have realized higher slaughter yield compared to groups G1 and G3, whereas the share of kidney fat was the same in all three groups of young cattle. Share of mass of internal organs was the lowest in young cattle of group G2 (2,47%) whereas in other two groups it was the same. Share of mass of other secondary slaughter products (head, tongue, tail, muscle part of diaphragm) in all three groups of young cattle was the same. Share of mass of round (I category part of the carcass) was the highest in young cattle of group G3 (29,86), and statistically significantly (P (lt) 0.05) lower in group G1 (28,39). Share of carcass parts of II category (loin, back, shoulder) was the lowest in young cattle of group G3 (23,655), and of carcass parts of category III (second thigh, second fore thigh, neck, breasts, ribs, belly) in young cattle of group G2 (44,45%).
AB  - U cilju ispitivanja faktora značajnih za rezultate vrednosti randmana klanja, izveden je ogled sa tri grupe junadi domaće simentalske rase različite telesne mase. Prva grupa (G1) junadi (n=6) bila je prosečne mase 509,00 kg (475-525), druga grupa (G2) junadi (n=7) bila je prosečne mase 554,29 kg (530-575) i treća grupa (G3) junadi (n=8) bila je prosečne mase 591,13 kg (580-615). Posle klanja izvršeno je pojedinačno merenje toplih polutki sa i bez bubrežnog loja, merenje mase unutrašnjih organa (bubrezi, jetra, pluća, srce, slezina) i merenje mase ostalih pratećih proizvoda klanja (glava, jezik, rep, mišićni deo dijafragme). Posle hlađenja polutke su rasečene u osnovne delove. Na osnovu dobijenih rezultata istraživanja utvrđeno je da su muška junad druge grupe (G2) domaće simentalske rase prosečne mase 554,29 kg, ostvarila veći randman u poređenju sa grupama G1 i G3, dok je učešće bubrežnog loja bilo isto kod sve tri grupe junadi. Učešće mase unutrašnjih organa najmanje je kod junadi grupe G2 (2,47%) dok je kod je kod ostale dve grupe bilo isto. Učešće mase ostalih pratećih proizvoda klanja (glava, jezik, rep, mišićni deo dijafragme) u sve tri grupe junadi je isto.

AB  - Problems which relate to production, health and reproduction in herds of high yielding cows very often occur due to insufficient knowledge and monitoring of energy reserves in cow organisms. Many researches and practical experiences in this field indicate significant relation between body condition and achieved results in production. Body condition of heads of cattle in certain stages of production cycle is important parameter of applied nutrition, but also entire technological procedure. In countries with developed cattle production, evaluation of body condition has for several years been main component of production practice on farms. It is considered that condition is very reliable indicator of the nutrition status and energy balance in the organism. Body condition score is subjective and practical method which enables precise assessment of deposited fat in the cow organism by observing and touching previously determined body regions and fields. There is considerable variability of the condition of cows in different stages of production cycle. Body condition of high yielding cows often comes out of the frame of optimal values for certain stage of production cycle. Decrease of production, disorders in health condition and fertility of cows indicate the nature of relation between inadequate body condition and stated problems. Shape and strength of the relation between production results and body condition score confirms its reliability. This is all indication of the need for wider application of this evaluation system. Based on body condition score, beside other important factors in the production cycle, there is realistic possibility to achieve more efficient production of milk from the aspect of energy. Main purpose of this paper was to present how the application of methods for body condition score and its significance for production practice can be functional.

U skromnim vrednostima telesna kondicija postepeno se vraća u periodu od 7 do 12 nedelje. Krave u prvih od 100 do 120 dana laktacije treba da imaju ocenu između od 2,50 do 3,25. Ocena telesne kondicije od 200 dana laktacije do perioda zasušenja treba da je između 2,75 i 3,50. Ishrana u periodu zasušenja treba da osigura ocenu između 3,25 i 3,50.

AB  - Population of Black and White cattle has high genetic potential for production of milk. It exists in very complex production conditions where problems occur which are often manifested in different health disorders, high percentage of culling and short productive life. Longevity parameters are calculated within defined time limits. Bottom limit is determined by date of birth, and top limit by date of culling. The knowledge of the strength of the influence of environment on the longevity of high yielding cows is important from the aspect of its inclusion into the model. According to individual significance of systematic factors, their objective assessment was carried out in order to evaluate the obtained results as precise and correct as possible. Previous studies of the average age of cows at culling from the herd indicated relatively short productive life and life in general of high yielding cows, which due to high percentage of culling effects the herd remount. Consequently selection differential is reduced and in this way realized selection effect is diminished. Objective of this paper was to investigate using appropriate methodology the longevity of high yielding Black and White cows of different genotypes through major systematic influences. Investigated cows according to their origin belong to European type of Black and White cattle in final stage of intensive improvement using Holstein-Friesian breed. Investigated sample included 331 cows. Average age of cows at culling is 2265±463.26 days or 6.21±1.27 years. Observed by cow genotypes, mean values varied from 2140.99 days (> 73% HF), 2247.51 days (58-73% HF) to 2406.97 days ( (lt) 58% HF). Average lifetime production was realized at the level of 25002.66±7755.39 kg of milk with 3.61±0.01% of milk fat.Bulls, sires of cows, class of HF genes and year of culling had highly significant effect (p≤0.01), whereas the effect of reason for culling was significant (p≤0.05) for life duration of cows.

Ovo bi, pored smanjenja troškova sa manjim udelom amortizacije u ceni koštanja, omogućilo bolje ukupne selekcijske rezultate preko nižeg remonta stada uz veći selekcijski diferencijal. Mnogo veća pažnja mora se posvetiti vremenu korišćenja krava u proizvodnji i uzrocima njihovog izlučenja. Najčešći uzroci izlučenja su: slaba mlečnost, smetnje u plodnosti, poremećaji posle teljenja, oboljenja nogu, bolesti organa za varenje, mastitis i dr.

AB  - Increase of production and improvement of the quality of milk, as well as of the intensity of fertility, are main prerequisites of modern cattle production. For the purpose of production of domestic Simmental bulls it is necessary to select the best cows from main herd. These heads as a rule represent approx. 1% of best cows in the controlled population primary in regard to production of milk and milk fat, but also in regard to body development, udder development and fertility traits. Fertilization of bull dams is done according to adequate system, where, for each dam, annually, bull, previously selected as sire, is determined, whose semen will be used for her insemination. Since the fastest way for selection and genetic progress is sire-son line, the most attention is directed to selection of bull sires. In Serbia, annually, only very few bulls are tested, which is insufficient for realization of greater and faster genetic improvement of production and reproduction traits of Simmental population of cattle. Therefore, centres for artificial insemination often import semen of elite bulls for planned insemination of Simmental bull dams, or borrow young bulls from abroad (waiting bulls) whose semen is used for insemination of main population. In this paper criteria for selection of cows into category of bull dams are presented as well as results relating to milk production, fertility, body development and type score of bull dams of Simmental breed in Central Serbia.
AB  - Povećanje proizvodnje i kvaliteta mleka kao i intenziteta plodnosti, osnovni su preduslovi savremene govedarske proizvodnje. Za potrebe proizvodnje bikova simentalske domaće rase neophodno je iz matičnog zapata odabrati najbolje krave. Ova grla, po pravilu, predstavljaju oko 1% najboljih krava kontrolisane populacije, pre svega u proizvodnji mleka i mlečne masti, a zatim i u telesnoj građi, građi vimena i osobinama plodnosti. Oplođavanje bikovskih majki se obavlja po odgovarajućem sistemu. Svakoj kravi se u toku jedne godine određuje bik čijim će se semenom osemeniti, a koji je prethodno odabran za oca budućih bikova. Budući da je najbrži put selekcije i genetskog unapređenja osobina putem linije otac-sin, izboru bikovskih očeva se pridaje najveća pažnja. U Srbiji se na godišnjem nivou testira jako mali broj bikova, što je nedovoljno za ostvarivanje nekog većeg i bržeg genetskog poboljšanja proizvodnih i reproduktivnih osobina populacije simentalske rase goveda. Iz tih razloga se centri za veštačko osemenjavanje odlučuju na uvoz semena za plansko oplođavanje bikovskih majki simentalske rase, ili pozajmicu mladih bikova iz inostranstva (čekajući bikovi) čije seme se upotrebljava za veštačko osemenjavanje matične populacije. Pored kriterijuma na osnovu kojih se vrši odabiranje krava u kategoriju bikovskih majki u radu su prikazani i rezultati mlečnosti, plodnosti, kao i telesne razvijenosti i ocene tipa bikovskih majki simentalske rase u centralnoj Srbiji.

abstract = "Increase of production and improvement of the quality of milk, as well as of the intensity of fertility, are main prerequisites of modern cattle production. For the purpose of production of domestic Simmental bulls it is necessary to select the best cows from main herd. These heads as a rule represent approx. 1% of best cows in the controlled population primary in regard to production of milk and milk fat, but also in regard to body development, udder development and fertility traits. Fertilization of bull dams is done according to adequate system, where, for each dam, annually, bull, previously selected as sire, is determined, whose semen will be used for her insemination. Since the fastest way for selection and genetic progress is sire-son line, the most attention is directed to selection of bull sires. In Serbia, annually, only very few bulls are tested, which is insufficient for realization of greater and faster genetic improvement of production and reproduction traits of Simmental population of cattle. Therefore, centres for artificial insemination often import semen of elite bulls for planned insemination of Simmental bull dams, or borrow young bulls from abroad (waiting bulls) whose semen is used for insemination of main population. In this paper criteria for selection of cows into category of bull dams are presented as well as results relating to milk production, fertility, body development and type score of bull dams of Simmental breed in Central Serbia., Povećanje proizvodnje i kvaliteta mleka kao i intenziteta plodnosti, osnovni su preduslovi savremene govedarske proizvodnje. Za potrebe proizvodnje bikova simentalske domaće rase neophodno je iz matičnog zapata odabrati najbolje krave. Ova grla, po pravilu, predstavljaju oko 1% najboljih krava kontrolisane populacije, pre svega u proizvodnji mleka i mlečne masti, a zatim i u telesnoj građi, građi vimena i osobinama plodnosti. Oplođavanje bikovskih majki se obavlja po odgovarajućem sistemu. Svakoj kravi se u toku jedne godine određuje bik čijim će se semenom osemeniti, a koji je prethodno odabran za oca budućih bikova. Budući da je najbrži put selekcije i genetskog unapređenja osobina putem linije otac-sin, izboru bikovskih očeva se pridaje najveća pažnja. U Srbiji se na godišnjem nivou testira jako mali broj bikova, što je nedovoljno za ostvarivanje nekog većeg i bržeg genetskog poboljšanja proizvodnih i reproduktivnih osobina populacije simentalske rase goveda. Iz tih razloga se centri za veštačko osemenjavanje odlučuju na uvoz semena za plansko oplođavanje bikovskih majki simentalske rase, ili pozajmicu mladih bikova iz inostranstva (čekajući bikovi) čije seme se upotrebljava za veštačko osemenjavanje matične populacije. Pored kriterijuma na osnovu kojih se vrši odabiranje krava u kategoriju bikovskih majki u radu su prikazani i rezultati mlečnosti, plodnosti, kao i telesne razvijenosti i ocene tipa bikovskih majki simentalske rase u centralnoj Srbiji.",

AB  - Results of the effect of direct and indirect selection on quantitative properties of milk production of first calving Simmental cows in Serbia, are presented in the paper. Analysis of quantitative phenotypic parameters was carried out in four breeding regions and certain number of smaller farms where 1319 daughters of 13 bull sires were reared. Results of the analysis were obtained by application of mathematical-statistical data analysis, using mixed models (Harvey, 1990). Mathematical-statistical analysis of data was carried out using linear methods with fixed effect, through method of least squares (LS method), and for evaluation of bull breeding value mixed model of random bull sire effect was used (BLUP method). Based on obtained results it was established that analyzed breeding region has statistically highly significantly (**P (lt) 0.01.) caused deviations of production phenotypes from general average. Season and year of calving (*P (lt) 0.05.) have caused significant variations of production properties. .
AB  - U radu su prikazani rezultati efekata direktne i indirektne selekcije kvantitativnih svojstava mlečnosti krava-prvotelki simentalske rase goveda u Srbiji. Analiza kvanitativnih fenotipskih parametara je obavljena u četiri odgajivačka područja i na više desetina manjih farmi na kojima je držano i gajeno 1319 kćeri, 13 bikova-očeva. Rezultati analize su dobijeni primenom matematičko-statističke analize podataka, korišćenjem mešovitih modela (Harvey, 1990). Matematičko-statistička analiza podataka je obavljena korišćenjem linearnih metoda sa fiksnim uticajem, preko metoda najmanjih kvadrata (LS metod) a za ocenu priplodne vrednosti bikova korišćen je mešoviti model slučajnog uticaja oca (BLUP metod).Na osnovu dobijenih rezultata ustanovljeno je da je odgajivačko područje statistički analizirano visoko značajno (**P (lt) 0.01.) prouzrokovalo odstupanja proizvodnih fenotipova od opšteg proseka. Sezona telenja i godina (*P (lt) 0.05.) su prouzrokovali značajna variranja proizvodnih osobina. Rezultati odstupanja osobina proizvodnosti pod uticajem godine telenja ukazuju na pozitivne tendencije u povećanju prinosa mleka . Značajna odstupanja (P (lt) 0.05) je izazvala godina telenja i na prinos mleka i mlečne masti. Godišnje doba početka laktacije krava obuhvaćenih našim istraživanjem pokazuje visokoznačajna odstupanja prinosa mleka i mlečne masti u odnosu na opšti prosek (P (lt) 0.01). Tako su junice oteljene u februaru , martu i aprilu imale značajno i visoko značajno više mleka i mlečne masti u odnosu na one koje su se otelile u drugim mesecima u godini. Interakcija odgajivačkog područja i sezone telenja je prouzrokovala visoko značajna odstupanja prinosa mleka (**P (lt) 0.01), međutim nije bilo statističkih značajnih variranja sadržaja mlečne masti. Prema analizi negativnih i pozitivnih BLUP rešenja (priplodne vrednosti) za prinos 4%MKM formirana je ocena ranga prema kojoj je bik broj 13. najbolje ocenjen, a bik-otac br.9 bio je rangiran na poslednje mesto. Krave - prvotelke obuhvaćene našim istraživanjem proizvele su 4868 kg mleka sa 183.03 kg mlečne masti , odnosno 3.76% mle. mast i 4693kg 4%MKM. Rezultati dobijeni nasim istraživanjima su značajno viši u odnosu na rezultate o mlečnosti iste rase (Lazarevic R. i sar., 1986). viši od onih koje je ustanovio Petrovic M.M. i sar. (1997 i 2006). Dobijeni rezultati su u saglasnosti sa onima koje su dobili Petrović M.D. i sar. (2005) i Pantelić i sar.(2008). Naši rezultati su pokazali da postoji pozitivan genetski trend u smislu kvantitaivnih osobina mlečnosti domaćih somentalskih krava. Poredeći naše rezultate i rezultate napred navedenih autora može se zaključiti da se prinos mleka simentalskih krava (matični zapat) u Srbiji godišnje uvećava za najmanje 100 kg mleka po kravi (zavisno od genetike, područja, odnosno tehnologija ishrane i držanja).
