1·The biological value, net protein utilization and protein efficiency ratio of the solubilized proteins in the preparation were higher than casein in the routine feed.

制剂中可溶蛋白的生物效价、净蛋白利用率、氮效能，也都高于混合饲料的酪蛋白。

2·There were almost linear increases in final body weight and daily body weight increment with the increase in dietary protein contents, while there was decrease in protein efficiency ratio.

随着饲料蛋白质含量增加，实验鱼的平均终重、增重率和日增重率呈线性增加，饲料系数呈线性下降，蛋白质效率也呈下降趋势。

3·The results showed that there were significantly higher weight gain, specific growth rate (SGR), feed efficiency and protein efficiency ratio (PER) in the fish fed the test diets containing 50.

的试验组鱼体增重、特定生长率、饲料效率和蛋白质效率等指标均显著高于其它试验组P。
