摘要
分别采用脱皮豆粕、大豆蛋白、发酵豆粕等大豆产品,等氮替代饲料中10%的鱼粉(对照组鱼粉35%,替代组鱼粉25%),饲养体重为0.06 g南美白对虾(Penaeus vannam eiBoone)一个月,结果表明,对照组(35%鱼粉)幼虾的增重率、成活率均最大,为1316%、97.5%;脱皮豆粕组幼虾的增重率为最低,仅783%;哈姆雷特大豆蛋白、比多福大豆蛋白、富肽蛋白(发酵豆粕)组幼虾增重率为1033%、983%、1050%,均显著高于脱皮豆粕组(P<0.05),但低于对照组(P<0.05);对虾体肌肉成分的分析显示,各组幼虾肌肉在水分、蛋白质含量方面没有显著差异。上述结果表明,大豆蛋白和发酵豆粕均为优于脱皮豆粕的鱼粉替代品。
To investigate the effect of replacing 10% fish meal by various soybean products on growth performance of P. vannamei（Boone） , dehulled soybean cake, soybean protein and fermented soybean cake were used, which had the same protein content as the replaced fish meal. Four diets, including normal fish meal diet（35% fish meal, NFM） , low fish meal diets（25% fish meal）added with dehulled soybean cake（DSY） , Hamlet soybean protein （HSB） , Biduofu soybean protein（BSB） and Futai fermented soybean（FSB） , were fed to P. vannamei with the body weight of 0. 06 g. After one - month feeding, shrimps fed with NFM diet had the highest growth rate（ 1316% ） and survival rate（97.5% ） , but the lowest growth rate（783% ）was for shrimps fed with DSY diet. The growth rates 1033%, 983% and 1050% were for shrimps fed with HSB, BSB and FSB diet, which were significantly higher than DSB shrimp （P 〈 0. 05） , but lower than NFM shrimp（P 〈0. 05）. There was no difference in water and protein content in muscles of all shrimps. The results showed that soybean protein and fermented soybean cake were better protein substitutes for fish meal than dehulled soybean cake, but the best substituting ration should be determined in future study.
