The effects of dietary vitamin E supplementation at graded doses (50,100, 200, 400 ppm) in experimental aflatoxicosis were studied using AFB1 @ 300 ppb in broilers. The feather score, leg score and toe hemorrhage scores were significantly affected when the birds were fed toxin alone. However, vitamin E supplementation could ameliorate the toxic effects. Aflatoxicosis also markedly increased the relative weights of liver, gizzard and proventriculus, nevertheless, supplementation of vitamin could correct the problem. A significant decrease in the levels of protein, cholesterol, Hb, PCV and RBC; increase in triglyceride, SGOT, SGPT, SGGT and ALP levels; whereas, no influence on serum glucose levels were observed due to aflatoxicosis. Dietary incorporation of vitamin E, at graded levels showed amelioration effect in dose dependent manner. Among the doses of vitamin E, 200 ppm showed the best result because beyond this level there was no further improvement. The study revealed that protective effect of vitamin E was only partial.
