Abstract
The study investigated the effect of supplementation of Vitamin E, Zn and Cr on growth performance and hematological characteristics of broiler chickens. The 240 day old Cobb 400 chicks were randomly distributed in eight groups consisting of 30 chicks in each. These chicks were kept on deep litter houses comprising of wood shavings. The supplementation of Vitamin E, zinc and chromium either individually or in combination improved the feed conversion ratio and body weight gain in broiler chicks. The body weight of broiler chickens at different age from day old to the 6th week were significantly different among treatments. The highest body weight was recorded in T8 groups. Heamoglobin, red blood corpuscles and white blood cells levels increased whereas heterophil: lymphocyte ratio statistically decreased with vitamin E, zinc or chromium supplemented groups either individually or in combinations.
