dc.description.abstractResearch was carried out on experimental sheep farm of the Institute for Animal Husbandry, Belgrade-Zemun. Trial included 60 lambs - crosses of F1 generation of Pirot Pramenka x Württemberg x Ile de France weaned at the age of 60 days. Nutrition treatment included study of three concentrated mixtures which were different in protein source (sunflower, soy bean and fish meal), i.e. share of proteins non-degradable at the level of reticulo-rumen: 43 (I) : 51 (II) : 58%(III). The effect of stated treatment in intensive fattening of lambs was monitored through production parameters. Obtained data was processed using standard statistical analysis. Average body mass of lambs at the beginning of trial, in treatments I: II: III was: 18,08: 18,12: 18,17 kg. After fattening of 75 days, final body mass of lambs in analogous treatments was: 30,78 (I) 33,52 (II) 35,17 kg (III) and average daily gain: 0,169: 0,205 : 0,227 kg. Per kilogram of realized gain of lambs, in analogous treatments, the following was consumed: 4,54 : 3,71 : 3,30 kg of dry matter of diet; energy: 33,77: 29,37 : 26,25 MJ; total proteins: 732 : 596 : 549 g. Research demonstrated that protein source in concentrate mixtures used in nutrition of fattening lambs (i.e. share of nondegradable protein in total proteins)had significant effect on production parameters, and the best performance was registered in lambs on treatment with fish meal (share of NP was 58%).en
dc.description.abstractU radu su prikazani rezultati uticaja različitih izvora proteina u obroku na intenzitet porasta i iskorišćavanje hrane i hranljivih materija kod odlučene jagnjadi u intenzivnom tovu. Ogled je izveden na 60 jagnjadi meleza F1 generacije pirotska pramenka x virtemberg x Il de frans, zalučenih sa 60 dana uzrasta, podeljenih u 3 grupe. Ishrana grla koncentrovanim smešama i lucerkinim senom je bila po volji. Ispitivan je efekat korišćenja tri smeše koje su se razlikovale u pogledu udela proteina nerazgradivog na nivou buraga: 43% (I), 51% (II) i 58% (III), što se postiglo korišćenjem različitih izvora proteina: suncokretove sačme (I) , sojine sačme (II) i ribljeg brašna (III), na proizvodne parametre jagnjadi u tovu. Statistička obrada dobijenih podataka je izvršena na računaru korišćenjem programa Stat.Soft, Inc. (2003). STATISTICA (data analysis software system), version 6, primenom standardnih matematičko - statističkih metoda. Jagnjad na tipovima ishrane I:II:III su ostvarila prosečan dnevni prirast: 0,169 : 0,205 : 0,227 kg. Konverzija suve materije (kg/kg prirasta) na analognim tretmanima je iznosila: 4,54 : 3,71: 3,30, energije (MJ NEM/kg): 33,77 : 29,37 : 26,25 , ukupnih proteina (g/kg): 732 : 596: 549 , PDIN (g/kg): 502 : 414 : 381 , PDIE (g/kg): 480 : 425 : 396.sr
