Curcumin Supplementation Enhances the Feeding and Growth of Largemouth Bass (Micropterus salmoides) Fed the Diet Containing 80 g/kg Fish Meal

Two feeding trials were conducted to evaluate the influence of dietary curcumin level on fish meal replacement with poultry by-product (PBM) in a largemouth bass (Micropterus salmoides) diet. In trial I, reference diet (R) contained 400 g/kg meal, and PBM replaced 60 80% (P16 P8). II, containing 80 (P8) served as control (C), was added at 5000 10000 mg/kg (C5 C10), respectively. Replacement significantly influenced feed intake, phosphorus retention efficiency (PRE), body lipid content, ratio consumption production (RCP), wastes carbon but did not result significant alternation weight gain, conversion (FCR), efficiencies nitrogen (NRE), (CRE) energy (ERE), viscerosomatic index (VSI), hepatosomatic (HSI), composition. The RCP, waste higher fed R than diets P16 P8. Curcumin supplementation FCR, waste, CRE, NRE, PRE, ERE, condition factor, VSI, HSI, composition, wastes. gain intake C10 C, while C5 C. Overall, minimum for could be dropped when used an alternative ingredient, obviously improve growth meal.
