Abstract The present study reports the pathomorphological changes in lymphoid organs induced by aflatoxicosis in broiler chicken. One hundred and eighty day-old broiler chicks were obtained and divided into six groups of thirty birds each (Group I, II, III, IV, V and VI) and they were given 0, 20, 40, 60, 80 and 100 ppb of AFB1 respectively. Severe lymphoid depletion along with decreased bursa weight were recorded in Group IV, V and VI. Spleenic atrophy and lymphoid depletion was noticed in all the groups except in Group V and VI on 45th day. Thymus revealed lymphoid depletion in all the groups throughout the experimental period.
