An experiment was conducted for a period of 42 days to assess the efficacy of herbal methionine (Nutrimethionine) supplementation on the performance of broiler chicken reared on deep litter. A total of 180 day old chicks (Vencobb 400) were divided into one control and three treatment groups, each group with three replicates of 15 birds per replicate. Group I (GI) of birds was kept as control and fed the basal diet without any supplemental Methionine. Group II (GII) of birds was fed the basal diet supplemented with synthetic DL-Methionine @ 100g per quintal. Group III (GIII) of birds were fed the basal diet supplemented with Nutri-Methionine @ 100g per quintal feed in the diet. Group IV (GIV) of birds was fed the basal diet supplemented with 50g Nutrimethionine and 50g DL-Methionine per quintal of feed in the diet. The body weight of birds fed combination of herbal Methionine (Nutrimethionine) and DL-methionine (GIV) was significantly (P< 0.05) higher when compared with the other treatment groups and control group. Also the groups supplemented with DL-methionine and herbal methionine had significantly higher body weights than the control group. Cumulative feed intake was comparable among the groups of birds fed diets supplemented with synthetic Methionine or herbal methionine or both. However, feed intake was significantly (P<0.05) higher in control group as compared to supplemented groups. The feed conversion ratio was significantly (P<0.05) better in GIII fed with combination of herbal and synthetic methionine as compared to other groups. FCR was comparative between the GII and GIII, which was significantly better than control group (GI). No significant (P>0.05) variation was observed in the defeathered weights among various groups. The dressed weight percentage was significantly higher in methionine-supplemented groups and was highest in GIV. Broiler chicken fed diets supplemented with methionine showed significantly (P<0.05) higher serum total protein values than the control group and was highest in GIV. A significant (P<0.05) decrease in serum cholesterol level with the inclusion of herbal methionine and was least in GIII.
