Effect of addition diffrent levels of copper sulfate and vitamin c to the diet on productive performance in broiler chickens

The current study was designedto investigated the effect of adding different levels (0, 100, 200 and 400 mg/kg feed) of copper sulphate and (500 mg/kg feed) vitamin C to the basic diet provided to the birds on some productive characteristics of broilers. In the study.Two hundred and eighty eight day-old Ross famels broiler chicks were assigned equally into eight dietry treatments for (35) days , with three replicates of 12 chicks each. Treatments: T1 = control treatment without additions. T2 = addition (500 mg/kg) of vitamin C. T3= addition (100 mg/kg) of copper sulphate. T4 = (100 mg/kg) of copper sulfate + (500 mg/kg) of vitamin C. T5 = (200 mg/kg) of copper sulphate. T6 = (200 mg/kg) of copper sulphate + (500 mg/kg) of vitamin C. T7 = (400 mg/kg) of copper sulphate. T8= (400 mg/kg) of copper sulfate + (500 mg/kg) of Vitamin C. The results indicated,there were significant increse(p≤0.05)in the average of body weight and Body weight gainin T3 and T4 birdscompared with control treatment during the study period (35) days.No significant effect on the rate of feed intake at age (0-7) days.Significant superiority (p≤0.05) for birds of T4 in the second and fourth weeks from the study, and a significant improvement in the feed intake for T3 and T1 in the fourth week .There was a significant superiority (p≤0.05)in feed intake for T1 in the fifth week of the experiment .Significant superiority (p≤0.05) in (FCR) in treatment T3 and T4 during all the study period.
