Effect of a non-hormonal feed additive, Cholymbi on growth, body composition and digestive enzyme activity of common carp, Cyprinus carpio.
Supplementation of pelleted feeds (30% crude protein) consisting of practical ingredients with 250, 375 and 500 mg Cholymbi/kg diet resulted significantly improved the growth of common carp, Cyprinus carpio. Highest final average weight was recorded with diet containing 500 mg Cholymbi/kg. Feeding Cholymbi to fish showed increased carcass protein and fat. Gut protease and hepatopancreas amylase activity were the highest with 500 mg Cholymbi/kg incorporated diet (T3). The results of the present study suggest that Cholymbi, a non-hormonal growth promoter could be effectively used in the diet of common carp. Further investigations are required to work out the optimal dosage required in the diet of common carp.
