用不同比例的酵母蛋白替代饲料中的鱼粉 ,进行室内分阶段饲养胡子鲶试验。经对各组鱼增重率、饲料系数及综合饲养效果等指标分析 ,表明在胡子鲶饲料中 ,酵母蛋白可替代鱼粉 ,其适合用量为 1 0 %左右(即替代 50 %左右鱼粉 ) Different proportions of yeast protein were used to replace the fishmeal in the feed, and the stubble catfish was tested indoors. The weight gain rate of each group, feed coefficient and comprehensive feeding results and other indicators analysis showed that the bearded catfish feed, yeast protein can replace fish meal, the appropriate amount of about 10% (ie, to replace about 50% of fish meal)
