To determine the differential influence of supplementing the broiler diet with two different sources of methionine namely, the herbal methionine (HM) and DL-methionine (DLM) and examine the influence on growth, performance and the effect on the antioxidant effects in 120 days-old broiler chicks were purchased and randomly assigned into 3 treatment groups (G1, G2 & G3) with 40 chicks in each group, having 4 replicates of 10 birds in each replicate. The diets included Corn soybean meal-based, control diet supplemented with DLM or HM. G1 as a control supplemented with DLM (3.4 and 2.3 kg/ton, respectively in starter and finisher ration) feed only, G2 was given feed supplemented with HM @ 6.5 and 5.2 kg/ton of feed, respectively in starter and finisher ration and G3 was provided commercial feed supplemented with combination of DLM and HM @ 1.7 + 3.2 and 1.15 + 2.60 kg/ton each, respectively in starter and finisher ration. The DLM-Methionine fed group showed significantly increased growth performance in live body weight and weekly body weight gain, feed consumption and feed conversion ratio as well as antioxidant parameters like TABARS, SOD, CAT and GPx significantly higher in group 1 as compared to group 2 and 3.Therefore, based on these findings, it can be suggested that herbal methionine can be effectively substituted for synthetic methionine in the poultry broiler diets up to the extent of 50%.
