Effects of various stocking density on productive performance and some physiological traits of broiler chicks

This experiment was carried out as a survey at the commercial poultry farm of broiler chickens in Duhok region namely Amedy, Akry and Sumail in order to study the effect of stocking density on the chick performance and some physiological traits. Chicks were divided into three stocking densities namely 8.66, 10.41 and 13.36 birds/m2. The results obtained are summarized as follows: Live body weights and feed conversion ratio at 7 weeks of age were non significant differences between different stocking densities. Data of feed intake was significantly high in 8.66 while mortality was significant high in stocking density of 13.36. Concerning hematological and blood serum parameters, data revealed insignificant differences among stocking density groups for triglycerides, total plasma protein, albumin, globulin, PCV and RBC count. While there were significant differences in glucose, total cholesterol, HDL, VLDL and Hb between different stocking densities.
