Abstract


This study was conducted to determine the effect of zinc on the productive performances, carcass yield and blood profiles of broilers. Experiment was done for a period of 35 days with a number of 60, day old broiler chicks. Birds were divided into four dietary treatment groups with 3 replications each having 5 birds per replication. The dietary treatment groups were; T0 (basal diet; no zinc), T1 (basal diet + 50 mg zinc/kg feed), T2 (basal diet + 100 mg zinc/kg feed), T3 (basal diet + 150 mg zinc/kg feed). Results revealed that body weight and body weight gain were significantly increased in the zinc supplemented group compared to the control group. Higher feed intake and better FE were also observed in the zinc supplemented group than the control group and the best performance was observed in the group fed 150mg zinc/kg feed (T3). Carcass yield was significantly higher in the groups fed dietary zinc. Net profit was slightly higher in the T3 group but not significantly (P.0.05) differed with the control group. However, T1 and T2 showed less profit even than the control group. Blood profile of the experimental birds including Hb, PCV, and ESR did not significantly differ among the groups. The results indicate that the addition of zinc in the broiler diet improves productive performances, carcass yield and increases net profit without affecting the health status of broiler. So, zinc can be used as an effective and useful micronutrient to improve the performances of broiler.
