Fermented rice polishings dietary supplementation sustainably enhanced growth performance, gut morphology, immune response and antioxidant status of Nile tilapia.

ABSTRACT: Fermentation of plant-derived by-products, including rice polishings (RP), is suggested for the sustainability of the aquafeed industry. In this study, fermented rice polishings (FRP) were incorporated into Nile tilapia diets at various levels: 0, 100, 200, 300, and 400 g/kg. Nile tilapia with an average initial weight of 19.25 ± 0.25 g/fish were divided into five groups (triplicates) and fed five test diets (R0, R10, R20, R30, and R40) for 85 days. Dietary FRP substantially increased final body weight, weight gain, specific growth rate, and protein efficiency ratio, but decreased feed conversion ratio compared to the control group (R0). According to regression analysis, dietary FRP at 210 to 230 g/kg leads to optimal growth performance. Fish fed with higher levels of FRP (R20, R30, and R4
