              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 (T0 ) and two treatments (T1 
                              & T2 ). Control group (T0 ) was offered basal diet 
                              deficient in natural or synthetic source of amino 
                              acids (choline, methionine, lysine & biotin). 
                              Treatment group T1 was fed with basal diet 
                              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 T2 was fed with basal diet 
                              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 T1 supplemented with 
                              herbal sources of amino acids were in confirmation 
                              with T2 supplemented with combination of synthetic 
                              amino acids suggesting that the polyherbal formula 
                              can successfully replace synthetic additives in 
                              feed.
