AB  - The effects of fixed non-genetic factors (farm, season of birth, year of birth, total number of lactations) and a continuous non-genetic factor (age at first conception) on the expression and variability of longevity traits such as age at culling, length of productive life, days in milk and cow efficiency index were investigated in 2548 Simmental cows in three farming areas. Based on the model used for the analysis of the effects of non-genetic factors, including the environment and cow age at first conception, on the expression and variability of longevity traits, the overall means for age at culling, length of productive life, days in milk and cow efficiency index were 2445.21±17.49 days, 1562.55±17.71 days, 1094.17±12.28 days and 58.68±0.32%, respectively. The effect of farming area, year of birth and lactation group on longevity traits was very significant (P lt 0.01), whereas the effect of season of birth was significant (P lt 0.05). Age at first conception had a highly significant (P lt 0.01) effect on age at culling, length of productive life and cow efficiency index, and no significant effect on days in milk (P>0.05). Based on the model used, the coefficients of determination (R2 ) were very significant (P lt 0.01) for all longevity traits, and ranged from 0.898 for age at culling to 0.959 for days in milk.
AB  - Uticaj fiksnih (farma, sezona i godina rođenja, ukupan broj laktacija) i kontinuelnih (uzrast pri prvoj oplodnji) sistematskih faktora na ispoljenost i varijabilnost osobina dugovečnosti kao što su uzrast pri izlučenju, dužina produktivnog života, ukupan broj muznih dana i indeks iskorišćavanja krava proučavan je na uzorku od 2548 simentalskih krava raspoređenih na tri odgajivačka područja.

Uticaj odgajivačkog područja, godine rođenja i grupe laktacija na osobine dugovečnosti bio je vrlo značajan (P lt 0.01), dok je uticaj sezone rođenja krava bio značajan (P lt 0.05). Uzrast pri prvoj oplodnji visoko značajno (P lt 0.01) je uticao na uzrast pri izlučenju, dužinu produktivnog života i indeks iskorišćavanja krava, dok na ukupan broj muznih dana nije imao značajan uticaj (P>0.05). Dobijeni koeficijenti determinacije (R2 ), na osnovu primenjenog modela, za sve osobine dugovečnosti bili su vrlo značajni (P lt 0.01) i kretali su se od 0,898 kod uzrasta pri izlučenju do 0,959 kod ukupnog broja muznih dana.

AB  - The effect of systematic and continuous environmental factors on 4% fat corrected milk (FCM) yield in 2805 Simmental cows over whole and standard lactations was evaluated using the general linear model. The test systematic or fixed factors included the effect of farm or breeding area, calving season, year of birth, season of birth, lactation group and interactions between year of birth and season of birth, breeding area and calving season, and breeding area and lactation group. The continuous factor analysed was the effect of age at first conception. The effect of breeding area, lactation group and calving season on 4%FCM yield over whole and standard lactations was found to be very highly significant (P lt 0.001). The interactions of fixed i.e. systematic factors involved in the model, including those between year and season of birth, breeding area and calving season, and farm and lactation group had a very highly significant effect (P lt 0.001) on 4% FCM yield over both whole and standard lactations. The age at first conception, as a continuous factor, showed a very highly significant effect (P lt 0.001) on 4% FCM yield over both whole and standard lactations. The model used to correct the 4%FCM yield over whole and standard lactations for the effect of systematic factors was very highly significant (P lt 0.001). The variance of the model accounted for 15.93% and 21.55% of the total variance in 4% FCM yield over whole and standard lactations, respectively. The resulting coefficient of determination (R2) in 4% FCM yield was 0.159 over whole lactations and 0.216 over standard lactations.

AB  - The effect of systematic and continuous environmental factors on milk performance traits over standard lactations in 2805 Simmental cows was evaluated using the general linear model. The systematic factors included the effect of farm or breeding area, calving season, year of birth, season of birth, lactation group and their interactions. The continuous factor analysed was the effect of age at first conception. The effect of farm, lactation group and calving season on standard lactation milk performance was found to be highly significant (P lt 0.01), excepting the effect of calving season on milk fat percent in standard lactations which showed statistical significance (P lt 0.05). The interactions between year and season of birth, farm and calving season, and farm and lactation group had a highly significant effect (P lt 0.01) on all performance traits studied. Age at first conception, as a continuous factor, had a highly significant effect (P lt 0.01) on milk yield and milk fat percent, and a non-significant effect on milk fat yield. The model used to correct the performance traits over standard lactations for the effect of systematic factors was highly significant (P lt 0.01). The variance of the model accounted for 20.06 and 37.31% of the total variance of milk fat yield and milk fat percent, respectively. The resulting coefficients of determination (R-2) ranged from 0.20 for milk fat yield to 0.37 for milk fat percent.

AB  - This study involves the analysis of two breeds [Naked Neck (NN) and Svrljig chickens (Sv)], that is, strains [White Naked Neck (WNN) and Black Svrljig strain (BSv)] of chickens (birds) of both sexes reared under a semi-intensive system until day 84 of age. At 28 days of age, the test birds were kept in a litter housing system (about 8 birds/m(2)), following which they were provided a free-range paddock at 4 m(2)/bird. The following parameters were evaluated in the two strains and sexes of broilers (totalling 56 chickens) aged 84 days: body weight at slaughter, carcass weight, yields of breasts, thighs, drumsticks, wings, pelvis, back, head, neck, feet, abdominal fat and giblets. At the end of the fattening period, the test broilers of both sexes of the WNN strain had higher values (P lt 0.05) for yield of drumsticks and thighs (34.20 to 33.93%), a statistically lower yield (P lt 0.01) of the back and pelvis (26.34 to 26.97%), and a somewhat higher live body weight (1587.07 to 1562.28 g). The difference was not statistically significant (P>0.05); however, a similar yield was obtained for ready to grill carcass (61.73 to 61.99%) when compared with the black Svrljig strain. The differences obtained were not statistically significant (P>0.05). In addition to the genotype (breed, strain), broiler sex had a statistically significant effect (P lt 0.001; P lt 0.01; P lt 0.05) on body weight, carcass yield, yields of drumsticks and thighs, wings, head, feet, giblets and abdominal fat. Specifically, male broilers were found to have higher live body weight (1669.29 to 1480.07 g), carcass weight (1342.86 to 1198.28 g), yields of head (5.13 to 4.39%), drumsticks and thighs (34.26 to 33.96%), feet (5.39 to 5.06%) and giblets (6.46 to 6.31%), whereas the relative yields of carcass (conventional processing (CP): 80.96 to 80.44%; ready to roast (RR): 73.02 to 72.19%; ready to grill (RG): 62.30 to 61.45%), wings (14.06 to 13.76%) and abdominal fat (1.13 to 1.07%) were higher in female broilers.

At the end of the fattening period, the test broilers of both sexes of the WNN strain had higher values (P lt 0.05) for yield of drumsticks and thighs (34.20 to 33.93%), a statistically lower yield (P lt 0.01) of the back and pelvis (26.34 to 26.97%), and a somewhat higher live body weight (1587.07 to 1562.28 g). The difference was not statistically significant (P>0.05); however, a similar yield was obtained for ready to grill carcass (61.73 to 61.99%) when compared with the black Svrljig strain. The differences obtained were not statistically significant (P>0.05). In addition to the genotype (breed, strain), broiler sex had a statistically significant effect (P lt 0.001; P lt 0.01; P lt 0.05) on body weight, carcass yield, yields of drumsticks and thighs, wings, head, feet, giblets and abdominal fat. Specifically, male broilers were found to have higher live body weight (1669.29 to 1480.07 g), carcass weight (1342.86 to 1198.28 g), yields of head (5.13 to 4.39%), drumsticks and thighs (34.26 to 33.96%), feet (5.39 to 5.06%) and giblets (6.46 to 6.31%), whereas the relative yields of carcass (conventional processing (CP): 80.96 to 80.44%; ready to roast (RR): 73.02 to 72.19%; ready to grill (RG): 62.30 to 61.45%), wings (14.06 to 13.76%) and abdominal fat (1.13 to 1.07%) were higher in female broilers.",

AB  - The present study involves the analysis of the chemical composition of white meat (breast muscles) and dark meat (leg muscles) of broilers in extensive indoor and free range systems. The length of fattening period was 56 days. At 56 days of age, 6 male and 6 female broilers were randomly selected from each rearing system and slaughtered. Cooled carcasses were dissected into primal cuts. Breast and leg muscle (thigh and drumstick) samples were used for chemical analyses. The obtained results suggested that free range rearing system was more favourable than extensive indoor system, as it resulted in a significantly higher protein content and a lower fat content of white and dark chicken meat. Female broilers produced a higher fat content and a somewhat lower protein content as compared to males.

AB  - The effect of systematic environmental factors on gestation length in Simmental cows was evaluated by calculating the least squares mean (LSM) and its error (SELSM), by analysis of variance and by calculating the coefficient of determination (R2). The study involved Simmental cows reared at three locations, including the Zlatiborski Suvati farm (n=578), the Dobričevo farm (n=964) and individual private farms at the Voćar Farming Cooperative in Kotraža (n=1263). The analysis included gestation length in Simmental cows as affected by continuous systematic factors (age at first conception) and discontinuous factors such as farm, calving season, birth season, parity group, calf sex, type of birth and the interaction of these factors. The effect of age at first conception was statistically significant (P lt 0.05). The discontinuous factors had a very high significant (P lt 0.001) effect on gestation length. The coefficient of determination was as low as 0.086 (8.6%), undoubtedly suggesting the small effect of the non-genetic factors on gestation length, given the fact that the trait is biologically determined and that it shows low variability.

Uticaj uzrasta pri prvoj oplodnji bio je statistički značajan (P lt 0.05), dok uticaj svih diskontinuelnih uticaja na trajanje bremenitosti bio je vrlo visoko značajan (P lt 0.001). Koeficijent determinacije iznosio je svega 0.086 (8.6%), što nedvosmisleno ukazuje na mali uticaj paragenetskih faktora na ispoljenost dužine bremenitosti obzirom da je ona biološki data i da se odlikuje niskom varijabilnošću.

AB  - The effect of cow age at first insemination on productive and reproductive traits, as well as on longevity and lifetime production ones was examined in the Simmental cows housed at the 'Zlatiborski Suvati' (Mt. Zlatibor Pastures) Farm. The general linear model was used to calculate linear regression coefficients for the effect of age at first insemination on productive, reproductive traits, longevity traits and lifetime production traits The calculated linear regression coefficients suggested that the age at first insemination had a statistically significant effect (P lt 0.05) on milk, milk fat and 4% fat milk production in whole lactations (bxy=1.508, bxy=0.056 and bxy=1.464), a very high significant effect (P lt 0.001) on the age at culling and cow utilisation index ((bxy=1.386 and bxy=-0.020), and no significant effect (P>0.05) on other longevity traits. The age of cows at first insemination did not significantly affect (P>0.05) fertility and lifetime milk and milk-fat production traits. The presented results suggest that cow age at first insemination should be included in the models used in estimating breeding values of dairy cows.

AB  - The aim of this work was parallel investigation of the producing characteristics of light line hen hybrids. Investigation enclosed two hen proveniences: Hisex Brown and Shawer 579. Within the period of 19 up to 63 weeks we followed next parameters: egg-laying hen body mass, mortality, food consumption and egg-laying capacity. Hens body mass on the beginning of the examination, within the 19 weeks of growth was, for Hisex Brown provenience 1607g, and for Shawer 579 provenience 1563g. Hisex Brown provenience achieved about 250 g higher body mass on the end of investigation. During the experiment, mortality at Hisex Brown egg-laying hen was a little bit smaller (5,40%), while the Shawer 579 had 5,56% of dead hens. Globally, the mortality at both hen hybrids was in the range of technological normative. The average consumption of the food at Hisex Brown provenience was higher and it was 127,28g, and at Shawer 579 provenience 125,14g. The average consumption of the nutrition for egg production at both provenience was the same (150g).

U periodu od 19. do 63. nedelje starosti praćeni su sledeći parametri: telesna masa nosilja, mortalitet, utrošak hrane i nosivost. Telesna masa kokoši na početku ispitivanja, sa 19 nedelja uzrasta, za provenijencu Hisex Brown, iznosila je 1607 g, a za provenijencu Shawer 579-1563 g. Veću telesnu masu na kraju eksperimenta, za oko 250 g postigle su nosilje provenijence Hisex Brown. U toku ispitivanja, mortalitet kod Hisex Brown nosilja je bio nešto manji (5,40%), dok je Shawer 579 imao 5,56% uginulih nosilja. Posmatrano u celini, mortalitet nosilja kod oba hibrida, bio je u granicama tehnoloških normativa. Prosečna dnevna potrošnja hrane kod provenijence Hisex Brown je veća i iznosila je 127,28 g, a kod Shawer 579-125,14 g. Prosečna potrošnja hrane za proizvodnju jajeta kod obe provenijence je bila ista (150 g).

Posmatrano u celini, mortalitet nosilja kod oba hibrida, bio je u granicama tehnoloških normativa. Prosečna dnevna potrošnja hrane kod provenijence Hisex Brown je veća i iznosila je 127,28 g, a kod Shawer 579-125,14 g. Prosečna potrošnja hrane za proizvodnju jajeta kod obe provenijence je bila ista (150 g).",

AB  - The aim of this work was to investigate production traits of meat type chickens of Hybro strain, which are present at our market for years, as well as Ross 308 strain, which are present also, but in considerable smaller volume. The investigation lasted 6 weeks and included 3000 chicks, that is 1500 chicks per strain. On the basis of obtained results, it was established that chickens of Hybro G strain had higher initial (47.3 g) and final average body weight (2.317,9 g), better feed conversion (1.925), smaller mortality (3.71 %) and higher value of performance index.
AB  - Cilj rada je da se ispitaju proizvodne osobine tovnih pilića provenijence Hybro, koji su već duži niz godina zastupljeni na našem tržištu i pilića provenijence Ross 308 koji su takođe prisutni, ali u daleko manjem obimu. Ispitivanje je trajalo 6 nedelja i obuhvatilo je 3000 pilića, odnosno 1500 po provenijenci. Na osnovu dobijenih rezultata utvrđeno je da su pilići provenijence Hybro G imali veću početnu (47,3 g) i završnu prosečnu telesnu masu (2317,9 g), povoljniju konverziju hrane (1,925), manji mortalitet (3,71 %) i veću vrednost proizvodnog indeksa.

AB  - The object of this study was to compare the basic carcass traits of Hybro strain, as one of the most represented at our market for many years, and Ross 308 strain, watch is also represented in our country, but in considerable sualler volume. The experimental examination included conformation measures dressing percentages, the yields of most important main carcass parts and abdominal fat in Hybro G and Ross 308 chicks. The differences between average body weight of chicks prior to slaughtering (Hybro G 2097.50 g; Ross 308 1977.25 g) were insignificant (P > 0.05). Significant differences between average values of many conformation measures (shank length drumstick circumference, breast depth) in chicks, Hybro G and Ross 308 were established (P  lt  0.05). The differences in average dressing percentages, as well as in yields of most important main carcass parts (breasts, drumsticks thighs) and abdominal eat between Hybro G and Ross 308 chisky were insignificant (P > 0.05).
AB  - Cilj ovog radaje da se uporedo ispitaju osnovne klanične karakteristike provenijence Hybro, kao jedne od najzastupljenijih na našem tržištu već duži niz godina i prove-nijence Ross 308 koja je takođe prisutna na našim prostorima, ali u daleko manjem obimu. Oglednim istraživanjem obuhvaćene su mere konformacije, klanični randmani i udeli najvažnijih osnovnih delova trupa i abdominalne masti pilića provenijenci Hybro G i Ross 308. Razlike prosečnih telesnih masa pre klanja pilića provenijenci Hybro G (2097,50 g) i Ross 308 (1977,25 g) nisu bile statistički značajne (P > 0,05). Zabeležene razlike prosečnih vrednosti apsolutnih pokazatelja, za veći broj osobina mera konformacije (dužina piska, obim bataka i dubina grudi) provenijenci Hybro G i Ross 308 bile su značajne na nivou 5%. Razlike u vrednostima randmana pilića provenijenci Hybro G i Ross 308 nisu pokazale statističku značajnost kao ni razlike procentualnog učešća naj-važnijih osnovnih delova trupa (grudi bataka i karabataka) i abdominalne masti.
