Effect of Supplementation of Ration with Neem Seed Cake on the Growth of Broilers

In order to ascertain the effect of various levels of neem seed cake (NSC) in ration on the growth, carcass and feed efficiency of broilers, the study was undertaken during August-September, 2006 at Poultry Experimental Station. Birds were divided into four groups: group A was kept as control (without NSC) and broilers in groups B, C and D were fed on ration with NSC at the level of 0.5, 1.0 and 1.5% /kg of feed, respectively. The results showed that all the parameters were significantly (P<0.01) different due to inclusion of NSC in broiler ration. The lowest feed (3779.8 g/bird) was consumed by the group C and highest (3838g/bird) by the group A. Better weight gain (1940g/bird), 1.94 FCR, 61.50 dressing % and Rs.30.32 net return was recorded in group C. The lowest morbidity, mortality and parasitic count were also noted in group C whereas non-significant results were obtained from edible parts. It was concluded that NSC has positive effects on broiler growth and its overall health. 1.0%/kg level of NSC produced optimally positive results and considered as cost effective.
