| Abstract | ||||
| The present experiment was carried out on 480 c0mmercial broiler chicks to determine the effect of adding copper sulphate on growth performance (body weight, food conversion, mortality) and on carcass quality (cholesterol and copper level in breast muscles but only copper concentration in liver). Four groups of birds, each of 120 chicks were used. Experimental diets were formulated from vegetable feeding stuffs, corn, and soybean meal and feed additives to cover the requirements in two phases of feeding program (First, from 1 to 21 days & second from 22 to 42 days) at the period of the experiment. The first group was fed on basal diet without any copper sulfate supplement. The second, third and fourth groups were fed on the basal diet supplemented with 150, 250, and 350 mg Cu SO4/ Kg feed respectively. The results demonstrated that supplementation of feed with copper sulphate, 250 or 350 mg\kg feed had significant positive effects on growth until the fourth week as compared to control group, but the second group fed 150 mg\kg copper sulphat had no significant difference during the experiment periods. On the other hand there were no significant difference in feed conversion ratio, mortality rate and copper level in the liver and breast muscle between the control group and the groups fed on different levels copper sulphate supplemented diets but cholesterol level in breast muscles was decreased with increasing copper sulphate level in the diet to 350 mg/kg. It was concluded that the addition of copper sulphate in high concentration (up to 350 mg\ kg) was safe and has a positive effect on growth and reduced cholesterol level in the breast meat. | ||||
