为研究发酵豆粕替代鱼粉对凡纳滨对虾( Litopenaeus vannamei)生长、肌肉成分和血淋巴非特异性免疫的影响, 设计了鱼粉含量为21%的对照组饲料, 以三种发酵豆粕W305、 W738和Y647等蛋白替代对照组饲料中6%的鱼粉, 配制成4种等氮饲料, 投喂平均体质量5. 1 g的凡纳滨对虾42 d. 结果表明: 1)各处理组在成活率上无显著差异, 对照组具有最高的增重率; 在发酵豆粕组中, 以Y647组的增重率最高, 饲料系数最低, 并达到对照组基本一致的水平; W305和W738组的增重率较对照组显著降低, 饲料系数显著增高; 2 )在肌肉成分方面, 各组水分和粗蛋白含量无显著差异, 与对照组相比, W305组肌肉粗脂肪含量显著增高, Y647组肌肉粗灰分含量显著降低; 3)三个发酵豆粕组的血淋巴酚氧化酶( PO)活性和W305组的总超氧化物歧化酶( T-SOD)活性均显著高于对照组. 结果表明, 发酵豆粕Y647可替代饲料中6%的鱼粉而不影响凡纳滨对虾生长性能, 并可提高血淋巴PO活性.

The present study was conducted to evaluate the effects of replacing fish meal with fermented soybean meal ( FSM) on growth, muscle composition and non-specific immunity of Litopenaeus vannamei. Four diets were designed as control diet with 21% fish meal, and three isonitrogenous diets with 15% fish meal, in which 6% fish meal was replaced by FSM products, W305, W738, Y647, respectively. The four diets were fed to white shrimp with initial body weight of 5. 1 g for 42 days. The results showed as follows: 1) There was no significant difference in survival rate among groups, and the control shrimp had the best growth. Among the three FSM groups, Y647 group had the highest weight gain ( WG) and the lowest feed conversion ratio ( FCR) , and reached the similar growth as control. Compared with control group, the WG of W305 and W738 group were significantly reduced, and FCR significantly increased. 2 ) There was no significant difference in moisture and protein contents in muscle, but W305 group had a higher crude fat content, and Y647 group had a lower crude ash in muscle when compared with control group. 3) Shrimp fed diets containing FSM had higher PO ac-tivity, and shrimp fed W305 diet had higher T-SOD activity in hemolymph than that fed control diet. In conclusions, the above results indicated that FSM Y647 could substitute 6% fish meal in diet without negative influence on growth, while promoting PO activity in hemolymph of white shrimp.
