The effect of feeding methionine as counteracting agent at four graded levels, i.e., 0.3, 0.5, 0.65 and 0.8 per cent in experimental aflatoxicosis created by feeding of aflatoxin B1 @ 300 ppb were studied using broilers. Contamination of broiler ration with aflatoxin resulted in a drastic reduction in the performance from growth, feed intake and feed efficiency standpoints. Feeding AF alone caused significant (P<0.05) increase in the relative weights of liver, heart, proventriculus and gizzard but decrease in the relative weights of spleen, bursa of Fabricius and RTC weights as compared to their control counterparts. The dietary methionine showed ameliorating effects in aflatoxicosis in a dose related fashion. Among the various doses of methionine, 0.8 per cent showed the best result.
