The effects of dietary methomin (a product developed by M/s. Vetcare, Bangalore containing methionine-hydroxy-analogue; equvalent to 43% activity of methionine along with chelated trace minerals viz., zinc, cobalt and manganese) were studied on feather, leg pathology and haemato-biochemical parameters of broilers in experimental aflatoxicosis (300 ppb). The study was carried out for 6 weeks on Anak 2000 commercial broilers (n= 360) at graded doses of methomin (0.6, 1.0, 1.3, and 1.6 %) as an ameliorating agent. Aflatoxicosis significantly (P<0.05) affected the leg, feather and toe hemorrhage scores, however, the dietary methomin could completely correct the pathological condition and the scores were found to be comparable with that of control group. The relative weights of liver, gizzard, heart, giblet and proventriculus were significantly (P<0.05) increased during aflatoxicosis; however, the dietary methomin could amend the problems, though partially. The serum total protein, cholesterol, Hb, PCV and RBC levels were decreased whereas; triglyceride level increased significantly (P<0.05) due to feeding of aflatoxin, however, addition of methomin in the diet could correct these problems in a dose dependent manner. The serum enzymes, i.e., SGPT, SGOT, SGGT and ALP activities were significantly (P<0.05) increased in aflatoxicosis, nevertheless, dietary methomin showed ameliorating effects on these parameters, though partially. The relative weights of ready-to-cook carcass as well as that of spleen and serum level of glucose remained unchanged during aflatoxicosis.
