AB  - The paper presents review of authors' own and other's results representing the effects of nutritional factors in order to overcome health problems of the people. In general we are presenting the effects and benefits of consuming organically bound selenium and omega-3 fatty acids. The purpose of this article is to show how to overcome the problems related a big amount of additive and other substances presented in human food, aero pollution, radiation and permanent stress in everyday life, which induce a lot of different diseases. This is the enough reason to develop special programme for producing 'designer milk', 'designer meat' or 'functional food' with purpose to preventing, reducing and healing those diseases. The purpose of this program is not only to keep a whole population in good health, but at the same time this kind of nutrients has a great comparative benefits for export our food in the west countries.
AB  - Nekretanje, zagađeni vazduh i voda, velika količina aditiva i rezidue pesticida u hrani karakteristike su urbanog načina života i oni deluju destruktivno na naš organizam. Takođe, oksidativni stres kao deo normalnog metabolizma oslobađa veliku količinu slobodnih radikala koje organizam često nije sposoban da neutrališe, dovodi do najtežih bolesti koje poprimaju razmere epidemije. U ovakvim uslovima življenja nauka pronalazi načine kako da putem hrane, pre svega osnovnih životnih namirnica mleka i mesa, popravi njen kvalitet, obogaćujući je pojedinim elementima koji su od vitalnog značaja za naše zdravlje, a time utiče i na prevenciju bolesti i usporavanje procesa starenja. Jedan od načina je i korišćenje funkcionalne hrane koja po definiciji predstavlja hranu koja pored osnovne hranljive vrednosti treba da sadrže i takve sastojke koji utiču na popravljanje opšteg zdravstvenog stanja pa i lečenja mnogih bolesti. U radu je na revijalan način predstavljen značaj organski vezanog selena i omega-3 masnih kiselina u mleku i mesu dobijenih od životinja u čije obroke se uključuju ove materije koje se izlučuju u njihove proizvode. Selen i omega-3 masne kiseline su od esencijalnog značaja ne samo za ljude već i za životinje, tako da jednovremeno značajno popravljaju njihove zdravstvene, produktivne i reproduktivne performanse.

AB  - Evaluation of phenotypic value of most present sheep breeds in Serbia is carried out as well as those populations which should have greater significance in the future. In this way, clear picture was obtained of strength and potentials of sheep production in different rearing systems, which will serve better defining of the direction of genetic-selection activities in the future. Researches have shown that there is high variability of traits depending on the observed factors. It is indicative that in the intensive system sheep breeds are forces of production direction meat and meat-wool, whereas in semi-intensive and extensive systems, predominant are breeds of tripartite direction. The best results in intensive rearing system were obtained in Mis sheep. In semi-intensive system, there is huge difference in body mass between Pirot improved sheep and Tsigai sheep, as well as between all investigated breeds in this system in regard to milk traits. Tsigai lambs realized higher body mass at the age of 90 days. Lipska sheep was dominant in regard to quantity of milk in lactation, but its fertility was the lowest. Mass of fleece was the lowest in sheep of Pirot improved population. There were no significant differences in regard to variability of the quantitative traits between sheep in extensive system, except in final body mass of lambs, where Svrljig and Pirot population were behind in comparison to Sjenica sheep.
AB  - Različiti sistemi gajenja ovaca, raznovrsnost ciljeva, nivo organizacije farmi, stepen uključivanja vladinih institucija u razvoju, implementaciji i održavanju procesa selekcije, su neki od faktora koji utiču na razvoj i napredak ovčarstva jedne zemlje. Stoga se prvi korak ka napretku sastoji od definisanja rasa, odgajivačkih ciljeva, odgovarajuće tehnike i metodologije za merenje proizvodnih osobina životinja. Na uspeh u ovom poslu najveći uticaj imaju: efikasnost kontrola i evidencije proizvodnih osobina, procedura procene genetskih parametara i odgajivačke vrednosti životinja i organizacija sistema za difuziju genetskog materijala. U ovčarstvu Srbije poslednjih nekoliko decenija je nastala vidna promena u sistemu gajenja ovaca, pre svega poboljšanjem ishrane. Pored toga sprovođeno je i oplemenjivanje lokalnih populacija selekcijom, planskim ili neplanskim ukrštanjem sa inostranim rasama. Takođe, neke uvožene rase adaptiravši se na nove uslove, gaje se u čistoj rasi, ali njihov proizvodni potencijal nije uvek adekvatno predstavljen. Konačno, dobijene su i nove domaće produktivnije rase: Mis ovca i Pirotska oplemenjena populacija. Cilj ovog rada je da izvrši procenu fenotipske vrednosti najzastupljenijih rasa ovaca u Srbiji kao i onih populacija koje bi trebale imati veći značaj u budućnosti. Time bi se dao doprinos sticanju prave slike o snazi i potencijalima ovčarstva Srbije u različitim sistemima gajenja i bolje definisao pravac daljeg genetsko selekcijskog rada. Istraživanja su pokazala da postoji visoka varijabilnost osobina u zavisnosti od svih posmatranih faktora. Indikativno je da se u intenzivnom sistemu forsiraju rase ovaca mesnatog ili kombinovanog tipa, smer meso i meso-vuna, dok u poluintenzivnom i ekstenzivnom sistemu dominiraju rase trojnog smera proizvodnje, meso-mleko-vuna. U intenzivnom sistemu gajenja, najbolje rezultate je pokazala populacija Mis ovce. U poluintenzivnom sistemu postoji vrlo značajna razlika u masi tela između pirotske oplemenjene ovce i cigaje, kao i između svih ispitivanih rasa ovog sistema u pogledu mlečnosti. Jagnjad cigaje su ostvarila najveću masu tela sa 90 dana. Lipska ovca po količini mleka u laktaciji dominira. Sa druge strane plodnost lipske ovce je najmanja, dok je masa runa najmanja kod ovaca pirotske oplemenjene populacije. Ekstenzivno gajenje ovaca je najviše zastupljeno u planinskim krajevima Srbije. Nema značajnih razlika u pogledu varijabilnosti kvantitativnih osobina između svrljiške, sjeničke i pirotske ovce, osim u završnoj masi tela jagnjadi, gde su Svrljiška i Pirotska populacija u zaostatku u poređenju sa sjeničkom ovcom.

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.
AB  - Efikasno korišćenje krava u intenzivnoj proizvodnji potrebno je da traje što duže. Vreme trajanja perioda od njihovog prvog teljenja do izlučenja iz stada treba da omogući poboljšanje ukupne životne produktivnosti. 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. Značajan broj istraživanja prosečne starosti krava pri izlučenju iz stada ukazuje na relativno kratak proizvodni i životni vek visokomlečnih krava.

abstract = "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., Efikasno korišćenje krava u intenzivnoj proizvodnji potrebno je da traje što duže. Vreme trajanja perioda od njihovog prvog teljenja do izlučenja iz stada treba da omogući poboljšanje ukupne životne produktivnosti. 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. Značajan broj istraživanja prosečne starosti krava pri izlučenju iz stada ukazuje na relativno kratak proizvodni i životni vek visokomlečnih krava. On se ispoljava preko visokog procenta izlučenja koji posledično utiče na veći remont stada. Cilj ovog rada je da se primenom odgovarajuće metodologije ispita dugovečnost visokomlečnih crno-belih krava različitih genotipova preko najvažnijih sistematskih uticaja. Ispitivane krave svojim poreklom pripadaju evropskom tipu crno-belih goveda koje se nalaze u završnoj fazi intenzivnog oplemenjivanja holštajn-frizijskom rasom.

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  - The effect of systematic factors on production traits over complete lactations was investigated in 2,805 Simmental cows born in 1982 and onwards. The cows were housed at three farms in different areas: at the Zlatiborski Suvati dairy farm, Zlatibor, at the Dobricevo Agricultural Farm, Cuprija and at private farms in the region of Kotraze. The systematic factors (farm, calving season, lactation groups, group (year x season of birth), farm x calving season and farm x lactation group interactions) and age at first conception had statistically highly significant (P (lt) 0.001) effects on all complete lactation traits, with the exception of the effect of calving season on complete lactation duration (P (lt) 0.05) and milk-fat content (P>0.05). No statistically significant effect was produced by age at first conception on complete lactation duration and milk-fat content (P>0.05). Determination coefficients ranged from 0.100 in complete lactation duration to 0.361 in milk-fat content.

AB  - Livestock production is important branch of agriculture in Republic of Serbia. Over 700.000 households are engaged in this production, which is over 55% of total number of households. Livestock production provides necessary products (milk, meat, eggs) for nutrition of domestic population. Also, livestock production provides raw materials for food industry (dairy plants, slaughterhouses, meat industry, conditory industry and leather industry). Livestock production is expected to provide high quality products for export, primarily beef and lamb meat. Chance/opportunity for export exists also for cheeses of high quality (especially sheep and goat cheeses) of defined origin and quality. Based on available data, current situation in livestock production is assessed as inviolable. Number of heads of all species of domestic animals and poultry has been constantly decreasing over the period of last 12 years. The greatest decrease of number of heads of livestock was recorded in years 2000, 2001 and 2002, in all species of domestic animals. During this period, number of cattle decreased by 18,6%, of pigs by 11,8%, sheep by 12,3%, number of goats by 54,1%, horses by 66,0% and poultry by 28,0%. So, by the end of 2007, number of cattle was 1.087.000, pigs 3.832.000, sheep 1.606.000, goats 149.000, horses 18.000 and poultry 16.422.000. Republic of Serbia will in its near future become member of European Union (EU) and World Trade Organization (WTO), which means that livestock production should prepare for competition on unique developed market, without any state trade barriers. Serbia has been preparing for this since 2006 when it signed bilateral agreement on free trade with neighbouring countries - Central European Free Trade Agreement (CEFTA) and in this way became part of the market and accepted the competition rules on the free market. Accession to EU and WTO includes liberalization of trade in livestock products, low possibility for import protection, implementation of quality standards (HACCP; ISO, Global GAP), reduction of the level of domestic support, discontinuing of export subsidies, increase of profitability and ability to be competitive on the international market.
AB  - Stočarska proizvodnja je značajna grana poljoprivrede u Republici Srbiji. Zastupljeno je u preko 700.000 domaćinstava (55% od ukupnog broja domaćinstava) i predstavlja značajnu privrednu granu koja učestvuje u formiranju društvenog proizvoda poljoprivrede sa 42%. Stočarskom proizvodnjom se obezbeđuju neophodni proizvodi (mleko, meso, jaja) za ishranu domaćeg stanovništva. Pored toga stočarstvo obezbeđuje sirovine za prehrambenu industriju (mlekare, klanice, konditorske industrije i industrija prerade kože). Od stočarske proizvodnje se očekuje da obezbedi kvalitetne proizvode za izvoz, pre svega juneće i jagnjeće meso. Šansu za izvoz imaju i kvalitetni sirevi (posebno ovčiji i koziji) sa definisanim poreklom i kvalitetom. Na osnovu raspoloživih podataka stanje stočarstva u Srbiji se ocenjuje kao nepovoljno. Broj grla kod svih vrsta domaćih životinja i živine u poslednjih dvanaest godina konstantno opada. Najveće smanjenje broja grla registrovano je u toku 2000., 2001., i 2002. godine kod svih vrsta domaćih životinja. U ovom periodu broj goveda je smanjen za 18,6%, broj svinja za 11,8%, broj ovaca za 12,3%, broj koza za 54,1% broj konja za 66,0% i broj živine za 28,0%. Tako da je na kraju 2007. godine broj grla goveda 1.087.000 , 3.832.000 grla svinja, 1.606.000 grla ovaca, koza 149.000, 18.000 grla konja i 16.422.000 živine. Republika Srbija u bližoj budućnosti postaće član Evropske unije (EU) i Svetske trgovinske organizacije (STO) što znači da se stočarska proizvodnja mora pripremiti za konkurenciju na jedinstvenom razvijenom tržištu, na kome neće postojati državne trgovinske barijere. Srbija na tom putu se priprema već od 2006. godine potpisivanjem bilateralnog sporazuma o slobodnoj trgovini sa susednim zemljama (Central European Free Trade Agreement (CEFTA) i samim tim postala deo tržišta i prihvatila pravila konkurencije na slobodnom tržištu. Pristupanje u EU i STO podrazumeva veću liberalizaciju trgovine stočarskim proizvodima, mala mogućnost zaštite od uvoza, implementacija standarda kvaliteta (HACCP; ISO, Global GAP), smanjenje nivoa domaće podrške, ukidanje izvoznih subvencija, povećanje profitabilnosti i sposobnost da se izdrži konkurencija na međunarodnom tržištu.

Number of heads of all species of domestic animals and poultry has been constantly decreasing over the period of last 12 years. The greatest decrease of number of heads of livestock was recorded in years 2000, 2001 and 2002, in all species of domestic animals. During this period, number of cattle decreased by 18,6%, of pigs by 11,8%, sheep by 12,3%, number of goats by 54,1%, horses by 66,0% and poultry by 28,0%. So, by the end of 2007, number of cattle was 1.087.000, pigs 3.832.000, sheep 1.606.000, goats 149.000, horses 18.000 and poultry 16.422.000. Republic of Serbia will in its near future become member of European Union (EU) and World Trade Organization (WTO), which means that livestock production should prepare for competition on unique developed market, without any state trade barriers. Serbia has been preparing for this since 2006 when it signed bilateral agreement on free trade with neighbouring countries - Central European Free Trade Agreement (CEFTA) and in this way became part of the market and accepted the competition rules on the free market. Accession to EU and WTO includes liberalization of trade in livestock products, low possibility for import protection, implementation of quality standards (HACCP; ISO, Global GAP), reduction of the level of domestic support, discontinuing of export subsidies, increase of profitability and ability to be competitive on the international market., Stočarska proizvodnja je značajna grana poljoprivrede u Republici Srbiji. Zastupljeno je u preko 700.000 domaćinstava (55% od ukupnog broja domaćinstava) i predstavlja značajnu privrednu granu koja učestvuje u formiranju društvenog proizvoda poljoprivrede sa 42%. Stočarskom proizvodnjom se obezbeđuju neophodni proizvodi (mleko, meso, jaja) za ishranu domaćeg stanovništva. Pored toga stočarstvo obezbeđuje sirovine za prehrambenu industriju (mlekare, klanice, konditorske industrije i industrija prerade kože). Od stočarske proizvodnje se očekuje da obezbedi kvalitetne proizvode za izvoz, pre svega juneće i jagnjeće meso. Šansu za izvoz imaju i kvalitetni sirevi (posebno ovčiji i koziji) sa definisanim poreklom i kvalitetom. Na osnovu raspoloživih podataka stanje stočarstva u Srbiji se ocenjuje kao nepovoljno. Broj grla kod svih vrsta domaćih životinja i živine u poslednjih dvanaest godina konstantno opada. Najveće smanjenje broja grla registrovano je u toku 2000., 2001., i 2002. godine kod svih vrsta domaćih životinja. U ovom periodu broj goveda je smanjen za 18,6%, broj svinja za 11,8%, broj ovaca za 12,3%, broj koza za 54,1% broj konja za 66,0% i broj živine za 28,0%. Tako da je na kraju 2007. godine broj grla goveda 1.087.000 , 3.832.000 grla svinja, 1.606.000 grla ovaca, koza 149.000, 18.000 grla konja i 16.422.000 živine. Republika Srbija u bližoj budućnosti postaće član Evropske unije (EU) i Svetske trgovinske organizacije (STO) što znači da se stočarska proizvodnja mora pripremiti za konkurenciju na jedinstvenom razvijenom tržištu, na kome neće postojati državne trgovinske barijere. Srbija na tom putu se priprema već od 2006. godine potpisivanjem bilateralnog sporazuma o slobodnoj trgovini sa susednim zemljama (Central European Free Trade Agreement (CEFTA) i samim tim postala deo tržišta i prihvatila pravila konkurencije na slobodnom tržištu. Pristupanje u EU i STO podrazumeva veću liberalizaciju trgovine stočarskim proizvodima, mala mogućnost zaštite od uvoza, implementacija standarda kvaliteta (HACCP; ISO, Global GAP), smanjenje nivoa domaće podrške, ukidanje izvoznih subvencija, povećanje profitabilnosti i sposobnost da se izdrži konkurencija na međunarodnom tržištu.",

AB  - Results of the effect of direct and indirect selection of quantitative traits of fertility and milk performance of first calving cows of Simmental breed in Serbia are presented. Investigation of genetic parameters of heritability (additive genetic variance in total phenotypic variability of quantitative traits) and analysis of milk traits was done in four breeding regions and several tenths of farms where 3980 daughters of 32 sires were housed and reared. Results of analysis were obtained by application of mathematical-statistical data analysis, using mixed models (Harvey, 1990). Mathematical-statistical analysis of data was done using linear methods, i.e. method of least squares (LS method). Based on obtained results it was established that bulls-sires and several paragenetic factors caused no significant variation of fertility traits in relation to general average (P (lt) 0.01). Quantitative milk traits of first calving cows, under the influence of breeding region, had significantly higher deviation from the general average (**P (lt) 0.01). Significant deviations (*P (lt) 0.05) were caused by year of calving on milk yield and yield of milk fat (4765.0 kg and milk fat 3.86%). Established heritability coefficients for reproductive traits were following: .102, .051 and .088, and milk traits .297, .207 and .197).
AB  - Najbrojnija populacija goveda u Republici Srbiji pripada Simentalskoj rasi (oko 500.000 plotkinja ili više od 80%). Ako se imaju u vidu tekuće promene u genetskom poboljšanju goveda i veoma velikom napretku u tehnologijama reprodukcije, očigledno da će se sadašnji programi morati menjati i poboljšavati. S obzirom na to, da je ekonomski značaj reproduktivnih i osobina mlečnosti visok neophodno je poznavanje pojedinih faktora koji utiču na plodnost i mlečnost krava, a oni se dele na genetske i paragenetske. Uspeh u poboljšanju plodnosti genetskim putem je dosta ograničen niskim vrednostima heritabiliteta, što ne znači da geni ne deluju na ovu osobinu, već da je vrednost aditivne genetske varijacije mala. Naslednost, odnosno proučavanje aditivne genetske varijanse u ukupnoj fenotipskoj varijabilnosti kvantitativnih osobina, predstavlja deo najvažjnijih istraživanja sa gledišta stvaranja populacije goveda visokih genetskih potencijala i odabiranja roditeljskih parova budućih generacija. Vrednosti koeficijenata naslednosti za osobine plodnosti su pod uticajem različitih faktora, kao što su: genotip životinje, uzrast, intenzitet selekcije, metod odgajivanja, ambijentalni uslovi i dr. Cilj ovih istraživanja je bio da se ispitaju važniji genetski parametri plodnosti i mlečnosti, odnosno naslednosti ovih kvantitativnih osobina radi izbora pravca i daljeg oplemenjivanja ove populacije. Prikupljeni podaci za analizu potiču iz četiri regiona - odgajivačka područja u Srbiji. Istraživanja su uključila 3980 krava - prvotelki simentalske rase, kćeri 32 bika - oca, koje su oteljene u periodu od šest godina (2002-2007). Sva ispitivana grla (krave - prvotelke) su držana vezano i slobodno u posedu privatnih farmera (od 8 do 65 grla po farmi) i bila su standardno hranjena, a razlike su bile u količini, odnosu i kvalitetu kabaste i koncentrovane hrane (područje gajenja). Matematičko-statistička analiza podataka obavljena je primenom mešovitog modela najmanjih kvadrata (LS-Least Squares) primenom programa najmanjih kvadrata (LSMLMW), Harvey, (1990). Različiti broj individua u pojedinim klasama kao i postojanje više uticaja (područje, godina telenja, sezona telenja, bikovi očevi) koji su delovali na ispoljavanje ispitivanih osobina, uslovio je analizu u kojoj je korišćen metod najmanjih kvadrata. Bikovi-očevi i niz paragenetskih uticaja nisu prouzrokovali značajno variranje osobina plodnosti u odnosu na opšti prosek (P (lt) 0.01). Kvantitativne osobine mlečnosti krava prvotelki su pod uticajem odgajivačkog područja imale visoko značajno odstupanje od opšteg proseka (**P (lt) 0.01). Značajna odstupanja (P (lt) 0.05) je izazvala godina telenja na prinos mleka i mlečne masti. Godišnje doba početka laktacije krava obuhvaćenih našim istraživanjem pokazuje značajna 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. Ustanovljeni koeficijenti heritabiliteta reproduktivnih svojstava koji su dobijeni našim istraživanjem su imali niske vrednosti i bili su nižeg nivoa u odnosu na one koje su dobili Petrović et al. (1998, 2001, 2006). Rezultati naslednosti osobina mlečnosti dobijeni našim istraživanjima su bili viši u odnosu na koeficijente za iste osobine koje su objavili Panić and Vidović (2006), niži u odnosu na rezultate istraživanja Petrović et al. (1999) and Kapš and Špehar (2004) a u saglasnosti sa koeficijentima heritabiliteta koje su u turskoj populaciji simentalskih goveda ustanovili Ulek and Tekun (2006).

AB  - Life of modern people in urban conditions is characterized by lack of movement, which is main condition for maintenance of health, presence of large amount of additives and pesticide residua in food of plant and animal origin and polluted air and water. If the presence of oxidative stress is added as part of normal metabolism occurring during degradation of nutritive substances, when great quantity of free radicals is released, which organism in these conditions often is not capable of neutralizing, the homeostatic mechanisms are disturbed and this leads to health disturbances and even severe illnesses. In such complex living conditions, science is facing the challenge of finding out the way to prevent diseases and slow the aging process using food, primarily basic food stuffs - milk and meat, enriching them with certain substances which are of vital importance to our health. One of the ways is use of functional food which should contain not only its main nutritive value but also such ingredients which have impact on improvement of general health condition, i.e. they have preventive and therapy effect. In this paper, a review of the significance of omega-3 fatty acids in human nutrition is presented. As essential substances they cannot be synthesized in the organism, but have to be introduced through diet. Also, the significance of some essential omega-6 fatty acids as well as their mutual relation, are presented. The role of omega-3 fatty acids in animal nutrition is also pointed out in this paper, introduced or consumed by animals either by grazing or as diet supplement, which influence improvement of their production, reproduction and health performances.

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).

AB  - In this paper current situation is analyzed and sustainable systems introduced in production of milk on small farms. Old production systems used on farms were the reason why milk production wasn't profitable activity and therefore livestock production in mountainous regions had complete collapse and pastures remained almost entirely deserted. In population of Pirot Pramenka sheep and local Simmental population of cattle, our analysis of breed productivity shows that effects in milk production are bad. Application of sustainable systems of milk production would increase the milk yield and revive dairy livestock production. After application of new systems regarding of breeding and farm management, milk yield in sheep cows was increased in average by 12%.

AB  - The main goal of this paper was to investigate the influence of some additives included into high yielding dairy cows rations to overcome the problems in early lactation. These substances directly affect the productive performances of dairy cows as well as udder health. The commercial name of investigated preparation is 'YEASTURE' and it is composed of live yeast cultures selected from three strains Saccharomyces cerevisisiae in combination with probiotic bacteria and enzymes (Lactobacillus casei, Streptococcus faecium, Aspergillus oryzae, Lactobacillus acidophilus, 1,3-b and 1,6 D-Glucan, hemicellulase, Protease, Cellulase, Alpha amylase) which have the ability to modify the fermentation in rumen stimulating the development of ruminal bacteria and increasing the fibre digestion. Effects of this preparation have been investigated on 60 Holstein-Friesian cows divided into two groups. The diets were identical, and trial group received also 10 g of preparation Yeasture daily. Application of Yeasture started 15 days prior to calving and lasted until 60th day of lactation As a research result improved in vitro disappearance of diet dry matter from roughage (alfalfa hay, maize silage and ensiled sugar beet pulp) was established. Preparation Yeasture influenced quantity and composition of the milk. The difference between trial and control group was 2.57 kg 4%FCM or 8.70% (P (lt) 0.01) and 7.16% milk fat (P (lt) 0.05).Trial group supplemented with Yeasture showed lower somatic cells count by 7.3 percent points what indicated better health of cow's udder. Based on the presented results it can be concluded that inclusion of preparation Yeasture into diets for dairy cows in transition period can be recommended.
AB  - Period zasušenja i rana laktacija karakterišu se brojnim problemima koji mogu da se uspešno premoste uključivanjem dodataka u hranu kao što su probiotici, kvasci, enzimi i dr. U radu su ispitani efekti preparata yeasture koji predstavlja kompoziciju ovih dodataka a koji je uključen u obroke krava dve nedelje pre i osam nedelja posle telenja u količini od 10 g po grlu dnevno. Uključivanje pomenutih dodataka uticalo je na poboljšanje svarljivosti suve materije kabastih hraniva (sena lucerke, silaže cele biljke kukuruza i siliranog rezanca šećerne repe) što je konačno značajno uticalo na poboljšanje proizvodnih performansi odnosno povećanje količine mleka za 10.86%. Jednovremeno pomenuti dodaci povoljno su uticali na popravljanje zdravstvenog stanja vimena krava što se odrazilo na smanjenje broja somatskih ćelija za 7.3 procentnih poena. Najvažniji parametri krvi pre i posle eksperimenta kretali su se u fiziološki optimalnim granicama. Navedeni argumenti su dovoljan razlog da se uključivanje pomenutih supstansi u obroke visokomlečnih krava u periodu zasušenja i rane laktacije preporuči u proizvodnji mleka.

The commercial name of investigated preparation is 'YEASTURE' and it is composed of live yeast cultures selected from three strains Saccharomyces cerevisisiae in combination with probiotic bacteria and enzymes (Lactobacillus casei, Streptococcus faecium, Aspergillus oryzae, Lactobacillus acidophilus, 1,3-b and 1,6 D-Glucan, hemicellulase, Protease, Cellulase, Alpha amylase) which have the ability to modify the fermentation in rumen stimulating the development of ruminal bacteria and increasing the fibre digestion. Effects of this preparation have been investigated on 60 Holstein-Friesian cows divided into two groups. The diets were identical, and trial group received also 10 g of preparation Yeasture daily. Application of Yeasture started 15 days prior to calving and lasted until 60th day of lactation As a research result improved in vitro disappearance of diet dry matter from roughage (alfalfa hay, maize silage and ensiled sugar beet pulp) was established. Preparation Yeasture influenced quantity and composition of the milk. The difference between trial and control group was 2.57 kg 4%FCM or 8.70% (P (lt) 0.01) and 7.16% milk fat (P (lt) 0.05).Trial group supplemented with Yeasture showed lower somatic cells count by 7.3 percent points what indicated better health of cow's udder. Based on the presented results it can be concluded that inclusion of preparation Yeasture into diets for dairy cows in transition period can be recommended., Period zasušenja i rana laktacija karakterišu se brojnim problemima koji mogu da se uspešno premoste uključivanjem dodataka u hranu kao što su probiotici, kvasci, enzimi i dr. U radu su ispitani efekti preparata yeasture koji predstavlja kompoziciju ovih dodataka a koji je uključen u obroke krava dve nedelje pre i osam nedelja posle telenja u količini od 10 g po grlu dnevno. Uključivanje pomenutih dodataka uticalo je na poboljšanje svarljivosti suve materije kabastih hraniva (sena lucerke, silaže cele biljke kukuruza i siliranog rezanca šećerne repe) što je konačno značajno uticalo na poboljšanje proizvodnih performansi odnosno povećanje količine mleka za 10.86%. Jednovremeno pomenuti dodaci povoljno su uticali na popravljanje zdravstvenog stanja vimena krava što se odrazilo na smanjenje broja somatskih ćelija za 7.3 procentnih poena. Najvažniji parametri krvi pre i posle eksperimenta kretali su se u fiziološki optimalnim granicama. Navedeni argumenti su dovoljan razlog da se uključivanje pomenutih supstansi u obroke visokomlečnih krava u periodu zasušenja i rane laktacije preporuči u proizvodnji mleka.",
