Abstract
This study aimed to know the effect of adding different levels of zinc sulphate and of some production traits and composetion for thigh and breast in broiler under heat stress, were used (120) chick type Rose and average weight (38) g / chick, and distributed chicks randomly to five nutritional treatments (24 birds / treatment) and by three replicates / treatment (8 birds /replicate) The transactions were as follows:
T1: fed normal diet without additions (. treatment control).
T2: fed normal diet +30 mg of zinc sulfate / kg feed.
T3: fed normal diet + 45 mg of zinc sulfate / kg feed.
T4: fed normal diet + 60 mg of zinc sulfate / kg feed.
T5: fed normal diet + 75 mg of zinc sulfate / kg feed.
At the end of the experiment were studied some productivity features such as the live body weight, weight after slaughter, the weight and the percentage of edible entrails and non-edible and make chemical analysis of the two pieces of the thigh and chest. The results mention significant increase (p≤0.05) in body weight and body weight after slaughter in T2, T3, T4 and T5 in compared with T1. While the chemical analysis for chest show that the protein content higher significantly (p≤0.05) in T2,T3,T4 and T5 in compared with T1 and lowered in fat content in T2,T3,T4 and T5 in compared with T1 . Either deterministic thigh has maintained its content protein within normal ratios and gave the two treatments T1, T5 highest content of fat and this we can deduce that the addition of zinc sulphate in different concentration to the broiler diet led to reduce the side effects of heat stress and keep protein content of chicken's meat as normal
