AB  - Results of the investigation of the effect of the level of nondegradable protein in concentrate mixtures on digestibility of nutritive substances in fattening lambs are presented in this paper. Physiological research included 18 male lambs crosses Pirot Pramenka x Württemberg x Ile de France, average body mass of approx. 35,0 kg, divided into three groups. Lambs were fed iso-protein concentrate mixtures which differed in relation to share of protein non-degradable at the rumen level: 43% (I), 51% (II) and 58% (III). Trial results indicate that the level of protein adoption was not under the influence of investigated treatment, considering that digestibility coefficients were: 52,58% : 51,30% : 55,12%. With the increase of share of nondegradable protein in concentrate mixtures (43: 51: 58%), also tendency of increase of fat digestibility was observed: 76,13 : 77,98 : 87,17%, but decrease of degree of cellulose digestion: 67,40 : 45,87: 22,39% and NFE: 83,87 : 76,05 : 82,96%.
AB  - Fiziološka istraživanja su obavljena na eksperimentalnoj farmi ovaca Instituta za stočarstvo Beograd-Zemun. Ogledom je bilo obuhvaćeno 18 muške jagnjadi meleza F1 generacije : pirotska pramenka x virtemberg x Ile de France, prosečne telesne mase oko 35,0 kg, raspoređenih u tri grupe. Ishrambeni tretman je podrazumevao ispitivanje efekata različitih nivoa na svarljivost hranljivih materija. Dobijeni podaci su obrađeni standardnom statističkom analizom. Prosečni koeficijenti svarljivosti ukupnih proteina kod jagnjadi na tretmanima I:II:III su iznosili: 52,58% : 51,30% : 55,12%; masti: 76,13: 77,98: 87,17%; celuloze: 67,40 : 45,87: 22,39% i BEM-a: 83,87 : 76,05 : 82,96%. Ova istraživanja su pokazala da su sa aspekta svarljivosti hranljivih materija, najpovoljnije rezultate ostvarila jagnjad na tretmanu sa 58% nerazgradivog proteina.

AB  - The examination was made on the effect of systematic factors (parturition group, calving season, birth type, calf gender, and birth type-calf gender interaction) and age at first conception on the expression of reproductive traits (gestation length, service period, fertility intensity and calf birth weight) in 143 Simmental cows. The overall mean (μ) for gestation length, service period, intercalving period and calf birth weight was 284.14 days, 153.82 days, 416.92 days and 35.40 kg, respectively. The parturition group effect on all fertility traits was highly significant (P lt 0.01). The calving season statistically significantly (P lt 0.05) affected the intercalving period and calf birth weight. Birth type induced very significantly longer gestation (P lt 0.01) and higher calf birth weight in singles (P lt 0.01) and significantly longer service period in twins (P lt 0.05). Calf gender had a very significant effect (P lt 0.01) only on calf birth weight, and the interaction between birth type and calf gender significantly affected gestation duration only (P lt 0.05). The regression effect of age at first conception on all fertility traits was not significant (P>0.05).
AB  - Na ispoljenost reproduktivnih osobina (dužina bremenitosti, servis period, intenzitet plodnosti i masa teladi pri rođenju) kod 143 krave simentalske rase, ispitivan je uticaj sistematskih faktora (grupe partusa, sezone telenja, tip rođenja, pol teladi i interakcija tipa rođenja i pola teladi) i uzrasta pri prvoj oplodnji. Opšti prosek (μ) za dužinu bremenitosti iznosio je 284.14 dana, servis period 153.82 dana, međutelidbeni interval 416.92 i masu teladi pri rođenju 35.40 kg. Uticaj grupe partusa na sve osobine plodnosti bio je visoko značajan (P lt 0.01). Sezona telenja statistički značajno (P lt 0.05) je uticala na međutelidbeni interval i masu teladi pri rođenju. Tip rođenja uslovio je vrlo značajno dužu bremenitost (P lt 0.01) i veću masu teladi pri rođenju kod jedinaca (P lt 0.01) i značajno duži servis period kod blizanaca (P lt 0.05). Pol teladi vrlo značajno je uticao (P lt 0.01) samo na masu teladi pri rođenju, dok je interakcija tipa rođenja i pola teladi značajno uticala samo na trajanje bremenitosti (P lt 0.05). Regresijski uticaj uzrasta pri prvoj oplodnji na sve osobine plodnosti nije bio signifikantan (P>0.05).
