Bioavailability of zinc from different organic zinc chelates and their effect on the growth, whole body, tissue zinc content, enzymes activity and proximate composition of L. rohita.

ABSTRACT: Minerals play an essential role in aquatic animals to maintain their normal physiological and metabolic functions. This feeding trial assessed the impact of various zinc sources on L. rohita performance. Dietary treatments included a Control group with zinc sulfate (226.25 mg/kg), and treatment groups with zinc citrate (150.15 mg/kg), zinc acetate (230.56 mg/kg), zinc monomethionine (244.75 mg/kg), and zinc gluconate (395.94 mg/kg). In 15 aquaria, 300 fish (15.84 ± 0.07g) were randomly distributed in triplicate groups. Results revealed significantly (P < 0.05) higher final body weight (FBW), feed conversion ratio (FCR), body weight gain (BWG), and sediment growth rate (SGR) for zinc gluconate fed fish compared to the other sources. Zinc gluconate fed L. rohita also exhibited the lowest fee
