Abstract
In this paper, results relating to nutritive value of rapeseed meal on production performances of fattening chickens are presented. Investigation was carried out on Ross 308 chickens in duration of 42 days. Control group of chickens (group 1) was fed standard mixture (starter, grower and finisher) based on corn, soybean meal and full fat soybean extruded as basic feeds, and share of rapeseed meal in diets for trial chickens was 10% (group 2) and 15% (group 3). Results showed that control group of chickens had realized final body mass of 2.250 kg, chickens of group 2 body mass of 2.243 kg, and group 3 had realized the lowest value - 2.181 kg. Feed conversion was equal in all three groups of chickens (1-1.864; 2-1.880; 3-1.861). Mortality was 3.16% in control group, 3.13% in group 2 and 7.16% in group 3. Production index had value of 270 in group 1, 268 in group 2 and 251 in group 3. Differences in all investigated parameters, with the exception of feed conversion, between group 3 and other groups were statistically significant (P (lt) 0.05). Presence of 15% of rapeseed meal in diets had exhibited depressive effect on production parameters of chickens and inclusion of this feed in higher percentage can have negative effect on success of broiler fattening. .U radu su prikazani rezultati nutritivne vrednosti sačme uljane repice na proizvodne parametre tovnih pilića. Ispitivanje je izvedeno na pilićima Ross 308 hibrida u trajanju od 42 dana. Kontrolna grupa pilića (grupa 1) hranjena je standardnom smešom (starter, grover i finišer) na bazi kukuruza, sojine sačme i sojinog griza kao osnovnih hraniva. Udeo sačme uljane repice u obrocima oglednih pilića bio je 10% (grupa 2) i 15% (grupa 3). Rezultati su pokazali da je kontrolna grupa pilića ostvarila završnu telesnu masu 2.250 kg, dok je grupa 2 imala telesnu masu 2.243 kg, a grupa 3, je bila najlošija sa 2.181 kg. Konverzija hrane je bila ujednačena kod sve tri grupe pilića (1- 1.864; 2-1.880; 3-1.861). Mortalitet je bio 3.16% kod kontrolne grupe, 3.13% kod grupe 2 i 7.16% kod grupe 3. Proizvodni indeks je imao vrednost 270 kod grupe 1, 268 kod grupe 2 i 251 kod grupe 3. Razlike po svim ispitivanim parametrima, osim po vrednosti konverzije hrane između grupe 3 i ostalih grupa su bile statistički značajne (P (lt) 0.05). Pokazalo se da učešće sačme uljane repice od 15% u obrocima depresivno deluje na proizvodne parametre pilića i da njeno uključivanje u većem procentu može imati negativnog uticaja na uspeh tova brojlerskih pilića.
