Abstract

A 60-day feeding trial was conducted to examine the effect and interaction of dietary ractopamine hydrochloride (Rac) supplementation in diets with varied levels of protein and lipid for L. calbasu fingerlings. To attain this, the fish body compositions, digestive and metabolic enzyme activity were assessed. In total, nine diets were fed in triplicates to four hundred and five healthy Calbasu, Labeo calbasu fingerlings, based on ractopamine supplementation, viz., control (0 mg/kg), T1 (10 mg/kg), and T2 (20 mg/kg). The diets were further assigned in different levels of protein and lipid, viz., 35% protein and 6% lipid, 30% protein and 9% lipid, and 25% protein and 12% lipid. At the end of the trial, it has been observed that the inclusion of ractopamine hydrochloride at 20 mg/kg(-1) of basal diet significantly (p 0.05) digestive enzyme activity, viz., amylase, lipase, and protease activity in the fed fish. Conclusively, it implies that adding ractopamine hydrochloride at 20 mg/kg of basal diet (high and low protein content) enhances the whole-body protein content and improves the metabolic enzyme activity in L. calbasu fingerlings. Hence, ractopamine hydrochloride has a beneficial effect in L. calbasu fingerlings and would be a desirable feed supplement for this new species culture system.
