外文摘要：A 56-day feeding trial was conducted to investigate the effects of replacing fish meal with cottonseed protein concentrate (CPC) (free gossypol < 7.9 mg/kg) in the diets on the growth, intestinal microflora, haematological and antioxidant indices of juvenile golden pompano (Trachinotus ovatus). Six diets were designed: fishmeal diets (FM) which contained 340 g/kg fishmeal, as well as five CPC diets, each with differing CPC concentrations (120, 240, 360, 480 and 600 g/kg) to replace the fish meal. The weight gain rate (WGR) and specific growth rate (SGR) showed no significant difference among groups (p > .05) with the dietary CPC level ranged from 0 to 360 g/kg. Serum cholesterol (CHO) of C36 and triglyceride (TG) levels of C36 and C12 were significantly higher than the FM (p < .05). Total protein (TP) levels of C12 were significantly lower than the FM (p < .05). Among the treatments, C36 had higher glutathione peroxidase (GSH-PX) and total superoxide dismutase (T-SOD) than FM (p .05). From the data analysis of 16s sequencing, with increasing CPC concentration, the proportion of harmful microbial taxa (ProteobacteriaandVibrio) increased. The results of this study support that CPC products are acceptable in practical diets for golden pompano. And the optimal dietary CPC replacement of golden pompano was estimated to be 259.3 g/kg.
