Abstract
Aim:The present study was conducted to evaluate the dietary addition of Emblica officinalis (Amla) fruit powder as a growth promoter in commercial broiler chickens.Materials and Methods:An experiment was conducted on 135 commercial broiler chicks (Ven-Cobb 400 strain) divided into three groups with three replicates of 15 chicks each. Three treatment groups were as follows – T1: Basal diet as per BIS standards; T2: Basal diet supplemented with 0.4% of E. officinalis fruit powder; and T3: Basal diet supplemented with 0.8% of E. officinalis fruit powder.Results:The average body weights at the end of the 6th week were significantly higher (p<0.05) in groups T2 and T3 compared to group T1. Feed intake, feed conversion ratio and feed cost per kg live weight production were similar among the treatment groups. The net profit per bird was the highest in group T2 (Rs. 19.22/bird) followed by group T3 (Rs. 17.86/bird) and the lowest in group T1 (Rs. 14.61/bird).Conclusion:Based on the results of the present study, it was concluded that dietary addition of E. officinalis (Amla) fruit powder had a positive effect on growth performance and net profit per bird in commercial broiler chickens.
Highlights
Growth promoters are chemical and biological substances which are added to diet with the aim to improve the growth, utilization of nutrients and in this way realize better production and financial results

Summary
Growth promoters are chemical and biological substances which are added to diet with the aim to improve the growth, utilization of nutrients and in this way realize better production and financial results. Their positive effect can be expressed through better appetite, improved body weight and feed conversion ratio (FCR), stimulation of the immune system and increased vitality, regulation of the intestinal microflora, etc. The Creative Commons Public Domain Dedication waiver (http://creativecommons.org/ publicdomain/zero/1.0/) applies to the data made available in this article, unless otherwise stated
