Effects Of Dietary Inclusion Of Fish Oil On Broiler Performance And Feed Utilization

This study was performed to investigate the effect of dietary supplementation of fish oil on broiler performance and feed utilization. Feed consumption body weight gain feed conversion ratio FCR carcass characteristics water consumption mortality protein efficiency ratio lysine efficiency ratio efficiency of energy utilization relative water consumption261643 production efficiency factor were studied. Two hundred unsexed broiler chicks 28 day-old Ross 308 were used. The Chicks were randomly distributed into 2 treatments experimental groups designated T1 and T2 each group has 4 replicates of 25 chicks. Birds were fed the experimental diets for 3 weeks. They were fed finisher diets from 29 to 49 day old in which fish oil was added to the iso-calaric and iso-nitrogenous diet T1 0 Control group and T2 3 fish oil. Two rations iso-nitrogenous and iso-caloric were formulated according the requirement of NRC National Research council. Adding fish oil improved feed intake body weight weight gain carcass weight dressing percentage protein ratio efficiency efficiency energy utilization lysine efficiency and production efficiency factor were significantly affected P0.01 and improved water intake feed conversion ratio were significantly affected P0.05 of broilers for the three weeks. No significant differences were observed for relative water intake. Therefore it is concluded that adding fish oil based diets improved broiler performance and feed utilization.
