摘要
选择南美白对虾作为试验研究对象,在相同饲养条件的基础上进行以酶解植物蛋白粉部分替代白鱼粉的试验,试验分为两组,每组设4个平衡土池,试验期90d。结果显示:投喂添加15%酶解植物蛋白粉替代12%白鱼粉和3%豆粕的对虾全价配合饲料,其产量、平均体重、特定生长率(SGR)、成活率都比对照组高,饲料系数比对照组低,且生产成本可进一步降低,表明对南美白对虾来说,应用酶解植物蛋白粉部分替代白鱼粉和豆粕在技术和经济上可行,具有潜在的经济效益和生态效益。
Under the same breeding condition, the Penaeus vannamei Boone were divided into two groups,a 90-day feeding trial was conducted to evaluate the potential of partially, replacing white fish meal with Pro-Bio in the formulation of diets for Penaeus vannamei Boone being cultured in out pond.The resuits of the present study indicated that Yield and Weight growth and Special growth ratio and Survival ratio were higher ,And Feeding efficiency was lower than control group when Penaeus vannamei Boone were fed with a formulated diets of containing 15% Pro-Bio. indicated that Pro-Bio could replace 12% white fish meal and 3% soybean meal without negative effects on technique and economy. Pro-Bio was a kind of better protein source for Penaeus vannamei Boone, and it has potentially economic profits and e- cological benefits.
