Abstract
The study aimed to determine the effect of zinc sulfate supplementation in different levels on blood proteins and immune status in broilers, (120) broiler chicks one day old were used with (38) gr. Initial weight divided randomly into (5) treatment groups (24 chick/each) with 3 replicates (8 chick /each) . The dietary treatment groups were:T1: ordinary diet (control), T2: ordinary diet +30 mg/kg Zinc sulfate, T3: ordinary diet +45 mg/kg Zinc sulfate, T4: ordinary diet +60 mg/kg Zinc sulfate, T5: ordinary diet +75 mg/kg Zinc sulfate. The blood samples were collected at 5, 15, 25, 42 day of study for detecting the post albumin, γ_ globulin, and antibody titration for Newcastle disease in serum. The results showed that there were significant increase P≤0.05 in γ_ globulin and antibody titration for ND in the serum of T2, and T3 and with significant decrease P≤0.05 in post albumin compared with the rest treatments. Hence the study showed that the zinc sulfate is important for improving immune status and disease resistance in broiler under heat stress.
