Abstract

The present study was designed and carried out to optimize the dose as well as to evaluate the efficacy and safety profile of liquid multivitamin and amino acid mixture EasyGrow TM following supplementation in drinking water for first 7 days of life in Vencobb 400 broiler chicks. Six hundred (600) day-old male chicks were randomly assigned to four groups with 6 replicates comprising 25 birds each (150 birds per group). Chicks were observed for clinical signs and mortality on daily basis; body weight was recorded on day 1, 7, 21 and 42. The cumulative mortality, body weight gain, FCR and EPEF were calculated and assessed to evaluate the safety and performance enhancing effect of EasyGrow TM . EasyGrow TM supplementation at 1, 3 and 6 ml/L drinking water for 7 days improved the performance of broiler chickens which was evident in terms of body weight, weight gain, FCR and EPEF. However, EasyGrow TM 1 ml/L treated group have shown a relatively higher body weight gain, lower mortality and better FCR as compared to other groups on day 42. The results from this study indicates that EasyGrow TM supplementation at all dose levels were safe and tolerated by broiler chickens upto 6 times the recommended dose and EasyGrow TM at 1 ml/L of drinking water could be used as an optimum recommended dose as it revealed a consistently gradual improvement in the performance with low mortality rate throughout the life cycle of Vencobb 400 broiler chickens.
