Sažetak
The use of rapeseed cake has been for years a great challenge to researchers and nutritionists regarding its inclusion rate in diets for different types and catego¬ries of poultry. The aim of this study was to determine the effects of 0%, 5% and 10% of rapeseed cake in feed mixtures on production traits of fattening chickens. In this research 360 male Cobb hybrid chickens were used. Chickens were divided in to 12 groups and fed to the age of 41 days. There were three treatments and four replications in this research. Each feeding treatment was applied in four cages with 30 birds each. Chickens were weighed on first, 20th and 41st day of research. At the end of the research feed consumption and feed conversion were determined as well as mortality of chickens. For each treatment ten chickens were randomly chosen and sacrificed after twelve hour fasting and slaughterhouse processed. Average body mass of chicks at the end of the research was: 2716.42, 2654.62 and 2657.46 g respectively. Feed conversion during the study was: 1.71, 1.70 and 1.71 kg/kg respectively. Since the results do not significantly differ is the use of rapeseed cake in fattening chickens diets is justified.
