AB  - Body condition of high yielding Holstein-Friesian dairy cows changes during the production cycle. It represents important indicator of achieved level of nutrition and degree of nourishment. BCS is a functional method, and integral part of the strategy and basis of corrective activities in farm management. BCS of cows in all phases of production cycle is important indicator of applied nutrition, but also of the technological process sin general. The amount of body reserves in form of fat tissue cow has before calving as huge impact on incidence of potential post-calving problems, production of milk, reproductive efficiency and health condition. Very often animals are culled from the herds prematurely, which shortenes the life exploitation of cows. Longevity is the ability to survice in certain production conditions. Life expectancy is from the economical aspect the most important functional trait of high yielding cows and represents necessary condition for sustainability of milk production over longer period. Average BCS of culled cows for the first stage of lactation was 3,35 (2,41-4,37) for the second stage of lactation 3,50 (2,59-4,59), for the third 2,22 (1,44-2,91) and the fourth 2,36 (1,37- 3,37). Variation coefficient (Cv) ranged from 12,59 to 16,82. Average age of culled cows was 2037,07 days or 5,58 years with variation interval of 742,00 to 5430,00 days. Age at culling showed high variability (Cv=45,69). Number of culled cows (n=34 or 32.69%) was the highest at the age of over 7 years (7,10-14,88). The same cows showed the highest variability in regard to longevity (Cv=17,97).

Ispod tog intervala BCS bilo je 5 grla ili 4,81%, a iznad 80 grlo ili 76,92%. U ovoj fazi proizvodnje u intervalu BCS od 3,76 do 4,75 bilo 31 krave ili 29,81%. U trećoj fazi od 84 ocenjene krave najviše grla (n=25 ili 29,76%) bilo je u intervalu BCS od 2,00 do 2,25. Ispod navedenog nivoa BCS bilo je 19 grla ili 22,62%, a iznad 40 krava ili 47,62%. U četvrtoj fazi od ukupno 66 ocenjena grla najviše krava (n=17 ili 25,76%) bilo je u intervalu BCS od 2,26 do 2,50. Ispod tog intervala BCS bilo je 26 grla ili 39,39%, a iznad 23 krave ili 34,85%.

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. Kao ozvor organskog selena korišćen je preparat Sell-Plex u kome je koncentracija selena iznosila 2000 mg/kg a izvor neorganskog selena bio je natrijumselenit. 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.

abstract = "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., U radu su ispitani efekti organskog i neorganskog selena u obrocima junadi u tovu. Kao ozvor organskog selena korišćen je preparat Sell-Plex u kome je koncentracija selena iznosila 2000 mg/kg a izvor neorganskog selena bio je natrijumselenit. 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  - 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  - It is well known that selenium has positive effect on the reproductive tract either in female or male individuals,
but cytology and biochemistry are not well elucidated. In this paper cytologically and microbiologically is shown that
bacteria Bacillus cereus and selenium have large positive and synergistic influence on maturation of oocytes in vitro.
This is caused by the bactericide effect on coliform bacteria which are abundant in the digestive tract. Taking account
that anus and vagina are often nearby each other and that even sterility can be caused by coliform bacteria in the upper
parts of the female reproductive tract, we found microbiologically and cytologically in oocyte in the presence of
coliform bacteria, and Bacillus cereus and selenium, that number of coliform bacteria decreases, and cytologically
oocytes cultured in such medium in vitro have more vitality than in culture medium without at least selenium supplement.
These investigations should be continued with the aim of optimization of conditions for maturation of oocytes
and fertilization in vitro for embryo transfer of domestic animals as well as model for in vivo reproduction.

AB  - Improvement of production capacity of cattle in terms of increasing the production of milk, milk fat and number of calves, greatly depends on phenotype and genotype variability, heritability and correlation between desirable traits, as well as on the production level of the cattle population. Heritability, as a value expressing and measuring average additive gene effect, is one of the major characteristic of quantitative traits from the point of view of creating genetically high-value cattle populations. Knowledge of the heritability is necessary in the estimation of the beeeding value of cattle and has significant impact on the selection of breeding method. Genetic correlations are very important in indirect selection where changes in one trait are induced through selection of other traits between which a genetic correlation exists. Genetic correlations can be determined in all cases where heritability coefficient can be calculated. This research included 3.461 first calving Simmental cows under control, with lactation concluded within one year. All first-calvers were reared on individual farms in the territory of Republic of Serbia. In this study, heritability and genetic correlations between the the following milk and fertility traits were investigated: duration of lactation (days)- DL, milk yield in standard lactation (kg)- MY, milk fat content in standard lactation (%)- MFC, milk fat yield in standard lactation (kg)- MFY, yield of 4% FCM in standard lactation (kg)- 4%FCM, age at first calving (days)- AC and duration of service period (days)- DSP.

AB  - Objective of this research was to determine the slaughter properties and carcass composition of carcass sides derived from young cattle of Domestic Spotted breed, of pre-slaughter weights of 500 (group A) and 600 kg (group B). Heavier cattle had higher share of kidney fat in carcass, whereas the share of offals showed no significant differences. Statistically significant difference was registered only in share of toungue (P (lt) 0.05), that was higher in cattle of group A. Share of extra/premium (tenderloin), I category (round) and II category (loin, back, shoulder) showed no significant differences between groups of cattle. Statistically significant difference (P (lt) 0.05) was established in the share of III category carcass parts. Share of forearm and chest was significantly higher in lighter cattle (3.55% and 7.95%) compared to heavier animals (2.89% and 6.33%), whereas the share of subshoulder was considerably lower in group A (6.89%) compared to cattle of group B (9.73%). Data obtained by dissection of main carcass side parts differed significantly in regard to the share of muscle tissue in round and belly, that was significantly higher in cattle of group A (P (lt) 0.05). Share of fat tissue (subcutaneous and intermuscular) was higher in cattle of group B in almost all carcass side parts, however, statistically significant difference between groups was determined only in round, back, neck and subshoulder. Also, share of bones in chest differed statistically significantly (P (lt) 0.05) and it was higher in group A (20.09%) compared to cattle of group B (15.52%).

Teža junad su imala veći udeo bubrežnog loja u trupu, dok se udeo iznutrica nije značajno razlikovao. Statistički značajna razlika je pronađena samo u udelu jezika (P (lt) 0.05), koji je bio veći kod junadi grupe A. Udeo delova ekstra (biftek), I kategorije (but) i II kategorije (slabine, leđa, plećka) nisu se značajno razlikovali između grupa junadi. Statistički značajna razlika (P (lt) 0.05) je pronađena u udelu delova III kategorije. Udeo podlaktice i grudi bio je značajno veći kod lakših (3.55% i 7.95%) u odnosu na težu junad (2.89% i 6.33%), dok je udeo potplećke bio znatno niži kod junadi grupe A (6.89%) u odnosu na junad grupe B (9.73%). Podaci dobijeni disekcijom osnovnih delova polutke su se statistički značajno razlikovali u udelu mišićnog tkiva u butu i potrbušini, koji je bio značajno veći kod junadi grupe A (P (lt) 0.05).

All first calvers were located on holdings of individual agricultural producers on the territory of the Republic of Serbia. Evaluation of the bull breeding value for lactation duration, milk production, milk fat yield, yield of 4% FCM and percentage of milk fat, was carried out by using the mixed model (BLUP), the calculation included random effect of bull sire and fixed effect of the region, year and season of calving. In this study, bull sires which had in two or three regions over 20 daughters - first calvers of Simmental breed. Number of first calving heifers ranged from 22 to 215 animals per bull sire.

AB  - This paper presents the results of a study on the effects of crossing domestic Simmental with French fattening breeds, Charolais and Limousin, on carcass and meat quality. The quality of carcasses from domestic Simmental cattle and its crosses (N = 30) was analysed by total dissection for the proportion of retail cuts in the carcass and carcass tissues. Traits of meat sensory and technological quality were investigated using standard methods on a total of 96 carcasses. The results showed that crossing did not have a significant effect on the proportion of retail cuts except the proportion of tenderloin steak, which was significantly higher (P (lt) 0.01) in crosses with Charolais (1.87%) and Limousin (1.85%) compared to the domestic Simmental breed (1.38%). However, highly significant differences (P (lt) 0.01) were established for the level of tissue content in the whole carcass. The highest proportion of muscle tissue (81.5%) was determined in carcasses obtained from Limousin crosses, whereas the highest content of bone (16.45%) and fat tissue (5.26%) was recorded in carcasses of domestic Simmentals. Crossing had positive effects on the sensory quality of meat except for marbling, which scored very low in the crosses. In general, comparison of the parameters of sensory and technological quality of meat from the studied genotypes showed that the most desirable quality properties of the meat were obtained from crosses of domestic Simmental and Limousin breeds.

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.

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  - 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  - Condition of animals is manifested through level of achieved nourishment. Body condition score (BCS) is a precise method of determination of reserves of deposited energy in form of subcutaneous fat tissue. Adequate body reserves are necessary requirement for maximal increase of milk production in the period of early lactation. Based on BCS we can precisely determine the number of cows which are bellow weight (excessively thin) or over weight (excessively fat). Body condition changes during lactation. Cows in early lactation are in the negative energy balance (NEB). Changes of the body condition should be over at the end of lactation. Objective is to have cows in optimal body condition during all production phases. Object of research was body condition of high yielding cows during production cycle. Realized sample size was 363 cows of Holstein-Friesian breed. Average BCS value of cows in dry period was 3.39 (2.37-4.41), at calving 3.56 (2.55-4.63), at lactation peak 2.30 (1.35-3.16) and in the mid lactation 2.50 (1.35-3.43). In dry period, most of cows (n=100 or 27.55%) ranged in BCS from 3.26 to 3.50. During dry period increase of body condition scores of cows occurred. At calving, most of heads (n=99 or 27.50%) ranged in their BCS from 3.51 to 3.75. During period of early lactation there was a significant decrease of the body condition of cows. At the peak of lactation a slight increase of body condition was recorded. At the peak of lactation, most cows (n=125 or 36.76%) ranged in BCS from 2.26 to 2.50. In the mid-lactation period, slight increase of body condition of cows occurred. During this period, most cows (n=88 or 27.32%) ranged in their BCS from 2.51 to 2.75. In general, realized average BCS results according to production phases deviated statistically significantly from target values.
AB  - Prikazani rezultati precizno ukazuju na ostvarene prosečne vrednosti, interval varijacije, standardnu devijaciju, koeficijent varijacije i značajnost odstupanja postignutih od ciljnih vrednosti OTK krava po fazama proizvodnog ciklusa. Prosečna vrednost OTK krava iznosila je na zasušenju 3.39 (2.37-4.41), teljenju 3,56 (2,55-4,63), vrhu laktacije 2,30 (1,35-3,16) i sredini laktacije 2,50 (1,35-3,43). Realizovane vrednosti ukazuju da je kod distribucije prosečnih OTK krava za sve tri telesne regije u prvoj fazi proizvodnog ciklusa od ukupnog broja koji čini 363 grla najviše (n=100 ili 27,55%) bilo u intervalu OTK od 3,26 do 3,50. Ispod tog intervala OTK bilo je 131 grlo ili 36,09%, a iznad 132 grla ili 36,36%. U drugoj fazi proizvodnog ciklusa od ukupno 360 ocenjenih krava najviše grla (n=99 ili 27,50%) bilo je u intervalu OTK od 3,51 do 3,75. Ispod tog intervala OTK bilo je 167 grla ili 46,39%, a iznad 84 grlo ili 23,33%. U ovoj fazi proizvodnje u intervalu OTK od 3,26 do 3,75 bilo je 193 krave ili 53,61%. Iznad tog nivoa OTK bilo je 94 grla ili 26,11%, dok je ispod bilo 73 krave ili 20,27%. Tokom perioda zasušenja došlo je do povećanja telesne kondicije krava.

abstract = "Condition of animals is manifested through level of achieved nourishment. Body condition score (BCS) is a precise method of determination of reserves of deposited energy in form of subcutaneous fat tissue. Adequate body reserves are necessary requirement for maximal increase of milk production in the period of early lactation. Based on BCS we can precisely determine the number of cows which are bellow weight (excessively thin) or over weight (excessively fat). Body condition changes during lactation. Cows in early lactation are in the negative energy balance (NEB). Changes of the body condition should be over at the end of lactation. Objective is to have cows in optimal body condition during all production phases. Object of research was body condition of high yielding cows during production cycle. Realized sample size was 363 cows of Holstein-Friesian breed. Average BCS value of cows in dry period was 3.39 (2.37-4.41), at calving 3.56 (2.55-4.63), at lactation peak 2.30 (1.35-3.16) and in the mid lactation 2.50 (1.35-3.43). In dry period, most of cows (n=100 or 27.55%) ranged in BCS from 3.26 to 3.50. During dry period increase of body condition scores of cows occurred. At calving, most of heads (n=99 or 27.50%) ranged in their BCS from 3.51 to 3.75. During period of early lactation there was a significant decrease of the body condition of cows. At the peak of lactation a slight increase of body condition was recorded. At the peak of lactation, most cows (n=125 or 36.76%) ranged in BCS from 2.26 to 2.50. In the mid-lactation period, slight increase of body condition of cows occurred. During this period, most cows (n=88 or 27.32%) ranged in their BCS from 2.51 to 2.75. In general, realized average BCS results according to production phases deviated statistically significantly from target values., Prikazani rezultati precizno ukazuju na ostvarene prosečne vrednosti, interval varijacije, standardnu devijaciju, koeficijent varijacije i značajnost odstupanja postignutih od ciljnih vrednosti OTK krava po fazama proizvodnog ciklusa. Prosečna vrednost OTK krava iznosila je na zasušenju 3.39 (2.37-4.41), teljenju 3,56 (2,55-4,63), vrhu laktacije 2,30 (1,35-3,16) i sredini laktacije 2,50 (1,35-3,43). Realizovane vrednosti ukazuju da je kod distribucije prosečnih OTK krava za sve tri telesne regije u prvoj fazi proizvodnog ciklusa od ukupnog broja koji čini 363 grla najviše (n=100 ili 27,55%) bilo u intervalu OTK od 3,26 do 3,50. Ispod tog intervala OTK bilo je 131 grlo ili 36,09%, a iznad 132 grla ili 36,36%. U drugoj fazi proizvodnog ciklusa od ukupno 360 ocenjenih krava najviše grla (n=99 ili 27,50%) bilo je u intervalu OTK od 3,51 do 3,75. Ispod tog intervala OTK bilo je 167 grla ili 46,39%, a iznad 84 grlo ili 23,33%. U ovoj fazi proizvodnje u intervalu OTK od 3,26 do 3,75 bilo je 193 krave ili 53,61%. Iznad tog nivoa OTK bilo je 94 grla ili 26,11%, dok je ispod bilo 73 krave ili 20,27%. Tokom perioda zasušenja došlo je do povećanja telesne kondicije krava. U trećoj fazi od 340 ocenjenih krava najviše grla (n=125 ili 36,76%) bilo je u intervalu OTK od 2,26 do 2,50. Ispod navedenog nivoa OTK bilo je 130 grla ili 38,23%, a iznad 85 krava ili 25,00%.

AB  - For the purpose of realization of the project of development of sustainable sheep production systems, in this paper, the major influences on production parameters of sheep in conditions of Stara Planina Mountain are investigated. Using the knowledge of gene effects, with good breeding programs, it is possible to realize, with more or less success, planned annual genetic progress of traits which are of interest to the breeders. This relates first of all on gain of lambs and milk yield in sheep. As already known, traits of body development and milk production vary depending on the factors of hereditary nature, but also factors of the environment. Therefore, the level of application of selection-breeding criteria is of great practical importance, which is confirmed also in this paper, and level of significance was statistically confirmed. Also, for complete creation of the program of improvement of sheep milk and meat production it is important to be aware of the effect of the breed itself, as well as of type of birth on production parameters, which was taken into consideration during investigation, processing and presentation of data in this paper. Obtained results show that majority of observed factors had significant effect on realized production of sheep.
AB  - Za razvoj održive ovčarske proizvodnje, između ostalog, neophodna je primena visokih kriterijuma selekcije i odgajivanja. Cilj ovog rada je da ukaže na praktičan značaj nivoa primene kriterijuma selekcije i odgajivanja u proizvodnji mesa i mleka ovaca u ekstenzivnom sistemu gajenja na Staroj planini. Proizvodnja mesa i mleka ovaca na Staroj planini je tradicionalna i istorijski posmatrano, uglavnom je zasnovana na gajenju pirotske pramenke, kao lokalne populacije u ekstenzivnim proizvodnim sistemima. Ova rasa kao i većina lokalnih populacija poseduje solidan genetski potencijal za prirast jagnjadi i mlečnost ovaca, ali da bi se taj potencijal ispoljio, potrebna je primena viših kriterijuma selekcije i odgajivanja, što uglavnom nije slučaj. Pored pramenke od druge polovine XX veka na području pirotskog dela Stare planine uvedena je u primenu i nova populacija-pirotska oplemenjena ovca. Ona se takođe u većini slučajeva gaji kao i pirotska pramenka, mada ove dve rase u genetskom smislu imaju veoma malo zajedničkog. Kao što je poznato, osobine telesnog razvoja i mlečnosti ovaca variraju u zavisnosti od mnogih faktora nasledne prirode ali i različitih spoljnih uticaja. Zato je nivo primene selekcijsko odgajivačkih kriterijuma, od velikog praktičnog značaja, što potvrđuju i rezultati istraživanja u ovom radu, a što je takođe i statistički potvrđeno. Pored toga za kompletno kreiranje programa unapređenja proizvodnje mesa i mleka ovaca, značajno je poznavanje uticaja same rase, kao i tipa rođenja na proizvodne parametre, o čemu se tokom istraživanja, obrade i prikazivanja dobijenih podataka vodilo posebno računa. Dobijeni rezultati istraživanja pokazuju da je većina posmatranih faktora imala značajan uticaj na ostvarenu proizvodnju. .

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.
AB  - Postojeći problemi u proizvodnji mleka, rezultatima reprodukcije i zdravstvenom stanju visokoproizvodnih krava mogu da se dovedu u vezu sa primenjenom tehnologijom ishrane. Važno pitanje u tehnologiji ishrane visokomlečnih krava predstavlja količina raspoložive energije (hrana, depoi masti, mišići) u ključnim fazama proizvodnog ciklusa (period zasušenja i rane laktacije). Deficit energije u kritičnim periodima proizvodnog procesa može da dovede do ozbiljnih poremećaja u proizvodnji, zdravlju i reprodukciji U početnoj fazi proizvodnje mleka najkritičniji je period maksimalne dnevne proizvodnje. Negativan bilans energije najizraženiji je u vrhu laktacije. Visok gubitak energije na račun telesnih rezervi predstavlja veliko opterećenje za metabolizam krava. Obezbeđenje adekvatne količine energije je složen uslov za svaku fazu proizvodnog ciklusa. OTK je subjektivan metod koji vizuelno i opipavanjem vrednuje količinu potkožne telesne masti. OTK je koristan alat za upravljanje mlečnim stadom. Idealna telesna kondicija je rang koji je u funkciji toka i faze laktacije. Procena rezervi energije u organizmu utvrđena preko OTK u osnovi predstavlja hranidbeni status grla vrednovan preko deponovanog masnog tkiva, pri čemu telesni okvir i masa grla imaju sekundaran značaj. Jedan od sistema za OTK krava koji je značajan za praksu je američki Virdžinija sistem modifikovan po Edmodsonu. Sistem za OTK kreiran je u obliku mape (karte) za ocenu visokomlečnih krava. Mapa je precizno pripremljena za svaki telesni region i polje koji se može smatrati važnim u dodeli ukupne OTK krave. Tri velika telesna regiona (slabine, karlica i koren repa) podeljena su osam polja na telu krave (slabine imaju četiri polja; karlica ima tri polja; koren repa ima jedno polje). Svako telesno polje se posebno ocenjuje i koristi kao pokazatelj telesne kondicije. Svako grlo ocenjeno je individualno za promene nivoa ocene duž skale od 1 do 5.

abstract = "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., Postojeći problemi u proizvodnji mleka, rezultatima reprodukcije i zdravstvenom stanju visokoproizvodnih krava mogu da se dovedu u vezu sa primenjenom tehnologijom ishrane. Važno pitanje u tehnologiji ishrane visokomlečnih krava predstavlja količina raspoložive energije (hrana, depoi masti, mišići) u ključnim fazama proizvodnog ciklusa (period zasušenja i rane laktacije). Deficit energije u kritičnim periodima proizvodnog procesa može da dovede do ozbiljnih poremećaja u proizvodnji, zdravlju i reprodukciji U početnoj fazi proizvodnje mleka najkritičniji je period maksimalne dnevne proizvodnje. Negativan bilans energije najizraženiji je u vrhu laktacije. Visok gubitak energije na račun telesnih rezervi predstavlja veliko opterećenje za metabolizam krava. Obezbeđenje adekvatne količine energije je složen uslov za svaku fazu proizvodnog ciklusa. OTK je subjektivan metod koji vizuelno i opipavanjem vrednuje količinu potkožne telesne masti. OTK je koristan alat za upravljanje mlečnim stadom. Idealna telesna kondicija je rang koji je u funkciji toka i faze laktacije. Procena rezervi energije u organizmu utvrđena preko OTK u osnovi predstavlja hranidbeni status grla vrednovan preko deponovanog masnog tkiva, pri čemu telesni okvir i masa grla imaju sekundaran značaj. Jedan od sistema za OTK krava koji je značajan za praksu je američki Virdžinija sistem modifikovan po Edmodsonu. Sistem za OTK kreiran je u obliku mape (karte) za ocenu visokomlečnih krava. Mapa je precizno pripremljena za svaki telesni region i polje koji se može smatrati važnim u dodeli ukupne OTK krave. Tri velika telesna regiona (slabine, karlica i koren repa) podeljena su osam polja na telu krave (slabine imaju četiri polja; karlica ima tri polja; koren repa ima jedno polje). Svako telesno polje se posebno ocenjuje i koristi kao pokazatelj telesne kondicije. Svako grlo ocenjeno je individualno za promene nivoa ocene duž skale od 1 do 5. Kontinuirano se koristi povećanje od 0,25 delova poena. Ceo sistem OTK funkcioniše sa 17 nivoa u okviru ukupne skale ocena posmatrane u intervalu od minimalne ocene u iznosu 1 i maksimalne u iznosu 5. Ocena 1 pokazuje mršavu kondiciju. Ocena 5 pokazuje izrazito tovnu kondiciju. Svaka faza proizvodnog ciklusa ima svoju optimalnu ocenu. Pod normalnim uslovima krave treba da gube telesnu kondiciju najviše od 4 do 6 nedelja. 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.
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. 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. Ispitivani uzorak uključio je 331 kravu. Prosečna starost krava kod izlučenja iznosi 2265±463.26 dana ili 6.21±1.27 godina. Posmatrano po genotipovima krava srednje vrednosti su bile 2140.99 dana (> 73% HF), 2247.51 dana (58-73% HF) i 2406.97 dana ( (lt)  58% HF). Prosečna životna proizvodnja ostvarena je na nivou od 25002.66±7755.39 kg mleka sa 3.61±0.01% mlečne masti. Bikovi-očevi krava, klasa HF gena i godina izlučenja imali su visoko značajan uticaj (p≤0.01), dok je uticaj razloga izlučenja bio značajan (p≤0.05) na trajanje života krava.

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.

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  - 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).

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  - U ovom radu se analizira postojeća situacija i uvode održivi sistemi u proizvodnju mleka na malim farmama. Stari proizvodni sistemi koji se koriste na farmama su razlog zašto proizvodnja mleka nije bila profitabilna aktivnost, što je dovelo do kolapsa stočarske proizvodnje u planinskim oblastima I skoro napuštenih pašnjaka. U populaciji pirotske pramenke i lokalne simentalske populacije goveda, naša analiza produktivnosti pokazuje da rezultati u proizvodnji mleka nisu bili dobri. Primena održivih sistema u proizvodnji mleka bi povećala prinos mleka i oživela proizvodnju u stočarstvu. Nakon primene novih sistema odgoja i upravljanja, prinos mleka kod ovaca i krava je povećan u proseku za 12%.

AB  - Cattle reproduction is the most important phase of production since in this phase heads of cattle are provided for renewal of the herd, production of milk and meat. In this paper the variability of age at calving and duration of service period was investigated according to year and season of calving on 3.461 first calving Simmental cows housed on farms of individual agricultural producers in Serbia. For the purpose of precise determination of the effects of different paragenetic factors all first calving cows included in this research were divided according to year of calving in 3 and to season of start of lactation in 4 groups. By method of least squares average service period of 115,19 days was established and age at first calving of 795,53 days. Year and season of calving had statistically significant effect (P (lt) 0,01) on age at first calving and duration of service period. Service period is one of the major fertility traits. Optimal duration of service period is 90 days, during which period involution of genital organs is fully completed and they are ready for next fertilization. One of the conclusions related to traits age of heifers at first fertilization and at calving is that these traits are more technological characteristics since they depend on nutrition level, herd renewal requirements and breeding goals.

AB  - Investigation of the production capacity of cattle for the purpose of increase of milk and milk fat production, as well as number of calves, greatly depends on phenotypic and genetic variability, heritability and correlation between desired traits, and on production level in the population. This research included 3.461 first calving cows of Simmental breed under control and reared on farms of individual agricultural producers on the territory of Republic of Serbia. Genetic correlations were calculated using equation of mixed model which included the effect of bull-sire, breeding region, year and season of calving: Yijklm = μ + Bi + Rj + Gk + Sl + eijklm. Coefficients of genetic correlation between service period and milk traits were following: duration of lactation 0,239, milk yield 0,089, percentage of milk fat 0,095, quantity of milk fat 0,105 and yield of 4%FCM 0,099. Correlation between service period and age at calving was 0,535. Genetic correlation between age at calving and milk traits was following: duration of lactation 0,245, production of milk 0,003, percentage of milk fat 0,531, quantity of milk fat 0,082 and production of 4%FCM 0,050.

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.

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.

AB  - Consumers are becoming more aware of the relationships between diet and health and this has increased consumer interest in the nutritional value of foods. This is impacting on the demand for foods which contain functional components that play important roles in health maintenance and disease prevention. Vitamin E, organically bound selenium and betacarotene are important antioxidant components of animal and human diets, and also unsaturated fatty acids and yeast and their roles in animal and human health and immune function are indispensable. The present review paper will discuss these nutrients in relation to antioxidant and health considerations and draw conclusions as to vitamin and mineral supplementation needs.
