Abstract

In view to study the role of herbal sources of essential amino acids in improving growth & performance, an experiment was conducted on seventy five day Vencob broiler chicks. Chicks were randomly divided into three groups (n=25), one negative control (T ) and two treatments (T & T ). Control group (T ) was offered basal diet deficient in natural or 0 1 2 0 synthetic source of amino acids (choline, methionine, lysine & biotin). Treatment group T was fed with basal diet 1 supplemented with polyherbal formulation comprising natural sources (herbs) that mimic the activity of amino acids (choline, methionine, lysine & biotin) @ 2Kg/tonne of feed while treatment group T was fed with basal diet 2 supplemented with combination of synthetic choline chloride (600gm/tonne), synthetic methionine (1kg/tonne), synthetic lysine (1kg/tonne) and biotin (150mg/tonne). Growth & performance parameters were recorded at weekly intervals and a metabolic trial for nutrient retention studies was conducted at the end of study. A significant increase in mean body weight gain, mean final body weight, feed efficiency & nutrient retention was observed in both the treated groups as compared to untreated control. The results of group T supplemented with herbal sources of amino acids were 1 in confirmation with T supplemented with combination of synthetic amino acids suggesting that the polyherbal 2

Methionine, choline and Lysine are universally recognized as the most two limiting amino acids in broiler diets based on corn and soybean meal (Baker, 1997; Han and Baker, 1991)

Summary

Introduction

Methionine, choline and Lysine are universally recognized as the most two limiting amino acids in broiler diets based on corn and soybean meal (Baker, 1997; Han and Baker, 1991). Feed rations that are high in plant proteins, such as soyabean meal can be used instead of synthetic amino acid supplements, but may lead to environmental pollution. It is difficult to design diet with sufficient Methionine and choline but without oversupplying protein or adding synthetic amino acids in crystalline form. Many herbs are rich source of these essential amino acids and mimic the activity like that of methionine, choline or biotin. These may be supplemented along with ration to replace synthetic in feed. The present experimental trial was conducted to evaluate efficacy of polyherbal coded formulation AV/CAP/18 (supplied by M/S Ayurvet Limited, Baddi, India) in comparison to synthetic additives in improving overall growth, productivity and performance in broilers
