Description
Summary:This study aimed to evaluate the effect of enzyme-hydrolyzed soybean (EHSB) to replace fish meal and chicken meal in channel catfish (Ictalurus punctatus) on the growth performance, serum biochemical indices and gastrointestinal structure of channel catfish. The channel catfish (initial weight: 21.25 ± 0.25 g) was fed four isonitrogenous, isolipidic and isophosphorous diets for 60 days. The control diet (CON group) contained 8% fish meal and 5% chicken meal. EHSB was used to replace fish meal (100%, RF group), chicken meal (100%, RC group), and 100% of fish meal and chicken meal (RFC group), respectively. The specific growth rate (SGR) and protein deposition rate (PR) of channel catfish in RF, RC and RFC groups were significantly increased compared to the control group and reached their peaks in RFC group (SGR: 2.92%, PR: 45.64%) (P
