Effect of Feeding Diet Contained Fish Oil on Broilers Performance and Blood Profile

Abstract

The study was conducted at the College Farm of Science and Technology of Animal Production, Sudan University of Science and Technology to investigate the effect of adding fish oil (3 % and 0%) to the finisher ration on broiler performance. Were used 200 birds were aged three weeks average weight was (683.3g).They divided into two groups, each group contains four replicatetwenty five birds. The ration (iso-nitrogenous and iso-caloric) was formulated according the requirement of (NRC) National Research council (1944). The objective of study to provide cheaper source of energy and to decrease the total cost. The effect of fish oil supplementation was studded on broiler performance feed intake (g/bird) , water intake (ml/bird) , relative water (ml/bird) , body weight (g/bird) , weight gain (g/bird) , feed conversion ratio (g/bird) , carcass weight (g/bird) ,dressing percentage (%) , blood analysis , protein ratio efficiency(g) , efficiency energy utilization(g) , lysine efficiency(g) and production efficiency factor(g) . Adding fish oil improved feed intake (g/bird) , water intake (ml/bird), body weight (g/bird), weight gain (g/bird) , carcass weight (g/bird) ,dressing percentage (%), protein ratio efficiency(g) , efficiency energy utilization(g) , lysine efficiency(g) and production efficiency factor significant(g) (P<0.01) and improved significantly (P<0.05) somebloodparameters of broiler chicks. No significant difference were the effaced for relative water (ml/bird) and feed conversion ratio (g/bird) (P>0.05) in this study.
