ABSTRACT

Objective of the experimental trial was to study the efficacy of supplementation of Methiorep, a herbal methionine supplement for improving growth, performance and carcass traits in broilers. 200 dayold unsexed broiler chicks (Vencobb) were used for the t r i al and were randomly allotted to two treatment groups, T0 & T1 comprising 100 chicks each. Group T0 supplemented with commercial feed only (no over and above Methionine- DLM supplementation) and in group T1 commercial feed supplemented with Methiorep (M/S Ayurvet Limited, India) @1.5 kg/tonne of feed. The experiment lasted for 42 days. Statistical analysis of results showed that in group T1 a significant (P<0.05) increase in mean final body weight (g) and live weight gain (g) was observed in comparison to unsupplemented control group T0. FCR in group T1 was found to be significantly (P<0.05) better from the control group T0. Significantly (P<0.05) improved dressing % and bursa weight (g) was observed in Methiorep supplemented T1 group in comparison to control T0 group, suggesting efficacy of Methiorep in improving immunity. Colour of fresh meat was significantly better and desirable in Methiorep supplemented group as compared to control group. Cooked meat colour, flavour, juiciness, texture and overall acceptability of T1 group was observed to be significantly (P<0.05) better. Numerically lower mortality occurred in Methiorep supplemented T1 group (6%) as compared to untreated control T0 group (8%). Considering growth performance, economics and other attributes the trial investigation revealed that over and above supplementation of Methiorep (M/S Ayurvet Limited, India) @1.5kg/tonne of feed alongwith commercial ration in broilers helped in improving growth, performance, feed efficiency, carcass traits. The product was found to be safe for usage.

Keywords: Methiorep, live weight gain (LWG), feed conversion ratio (FCR)
