This study assessed the nutritional potential of supplementing the practical diets for gibel carp (Carassius auratus gibelio var. CAS V) with a blend of fermented plant meal. The fermented plant meal (FPM) comprised mixed fermentation of rapeseed meal (RM), sprayed corn husk (SCH), rice bran (RB), palm meal (PM) and soybean meal (SM) in the proportion of 30:25:25:15:5. Four experimental diets were including a basal diet (the control diet, Con) and three FPM diets (supplementing 3 g, 5 g and 8 g FPM per 100 g diet in the basal diet, FPM3, FPM5 and FPM8, respectively). Each diet was randomly allotted to triplicate fish tanks where each tank had 25 fish weighing 28.00 ± 0.02 g. Fish from each group were fed twice per day until apparent satiation for 60 days. From the results, gibel carp from the FPM5 group had significantly higher feed efficiency and specific growth rate despite having significantly lower feeding rate than the control group. Fish from FPM5 group had significantly higher hepatosomatic index and viscera somatic index than those from FPM3 group. Meanwhile, serum antioxidants (including aspartate aminotransferase, catalase, glutathione peroxidase, superoxide dismutase and malondialdehyde) and intestinal digestive enzymes (including chymotrypsin, trypsin and amylase) of fish increased proportionately to amount of FPM in the diet. Fish fed on FPM5 diet had significantly higher expression of TOR and IGF-1 in the liver than those fed on the control diet. Further, supplemented with 8% of FPM significantly increased the relative mRNA abundance of hepatopancreas GH and S6K1. These results reveal that moderate level of dietary FPM significantly enhanced growth performance, antioxidant capacity, digestive enzymes activities and the expression of TOR signaling pathway genes of juvenile gibel carp, and dietary supplementation of 5% FPM is recommended for the juveniles base on the performance of growth and antioxidant properties.

这项研究评估了补充吉卜氏鲤（Carassius auratus gibelio）实际饮食的营养潜力变种 CAS V）与发酵植物粉的混合物。发酵植物粉（FPM）包括菜籽粉（RM），喷洒的玉米皮（SCH），米糠（RB），棕榈粉（PM）和大豆粉（SM）的混合发酵，比例为30:25:25 ：15：5。四种实验饮食包括基础饮食（对照饮食，Con）和三种FPM饮食（基础饮食中每100 g饮食分别补充3 g，5 g和8 g FPM，分别为FPM3，FPM5和FPM8）。每种饮食都随机分配给三个重复的鱼缸，每个鱼缸中有25条鱼，重28.00±0.02克。每组的鱼每天喂两次，直到明显饱食60天。从结果可以看出，尽管FPM5组的鱼的饲喂速率明显低于对照组，但它们的饲料效率和比生长速率却显着提高。FPM5组的鱼肝体指数和内脏体指数均明显高于FPM3组。同时，鱼的血清抗氧化剂（包括天冬氨酸转氨酶，过氧化氢酶，谷胱甘肽过氧化物酶，超氧化物歧化酶和丙二醛）和肠道消化酶（包括胰凝乳蛋白酶，胰蛋白酶和淀粉酶）与日粮中FPM的含量成比例增加。以FPM5饮食喂养的鱼在肝脏中的TOR和IGF-1的表达明显高于以对照饮食喂养的鱼。此外，补充8％的FPM可以显着增加肝胰腺GH和S6K1的相对mRNA丰度。这些结果表明，适量的饮食FPM可显着提高生长性能，抗氧化能力，
