Abstract
The aim of this research was to establish the influence of different quantities of rapeseed meal (RM) and calcium in feed mix on productive performance of 360 chicks divided in 12 groups during the 42-day experiment. It was found that chicks in group C (0% of RM) and E3-5 (10% of RM) achieved significantly (P<0.05) higher body gains than those in groups E6-11 (20 and 30% of RM) at the end of the experiment. In the same time average body weights of groups Ec,3,6,9 (0.8% of calcium) were significantly (P<0.05) higher than those in groups E1,4,7,10 (1.0% of calcium) and groups E2,5,8,11 (1.2% of calcium). We can conclude that 10% of RM in broiler diet didn’t have a negative effect on the production results. More than 0.8% of Ca in the broiler diet caused lower live weight.
