The result showed that higher special growth rate, feed conversion ratio and protein efficiency ratio were obtained when dietary probiotic was 2.0,3.0 and 4.0 than the control. 结果显示:实验组饲料对石斑鱼的成活率、特定生长率(SGR)、饲料转化率和蛋白质效率均优于对照组,初步认为添加2.0%-4.0%比较有利于石斑鱼的生长和饲料的利用。
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。
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。
Low protein diets can improve energy utilization efficiency from ME to NE, increase NE 2.1 %, decrease ratio Dlys / NE 2.2 % compared with the high protein diet. 低蛋白日粮提高了能量转化效率,使NE值提高2.1%,而Dlys/NE下降2.2%。
