| 摘 要： | 以酪蛋白为蛋白源，配合成蛋白含量分别为３５％，４０％，４５％，５０％和５５％的系列标准试验饲料，以稚鳖为试验对象，经６０天的饲育试验，观测到以４０％－５０％含量的区组增重效果较好，其中４５％含量组增重率最高，在以鱼粉和豆粕为蛋白质源，配合成的租蛋白质含量都为４５％的不同组合的饲育试验中，以５９％鱼粉与４５％豆粕的配合组饲料消化率与增重率为最高，饲料系数为最低。随着豆粕添加量的增加或减少，增重率也随之减低，这表明，甲鱼对豆粕蛋白的利用能力较低，在以鱼粉为主要蛋白源的饲料中，添加５％豆粕，能起蛋白质互补效应，但添加过量反而影响饲料蛋白质的利用率．

| Abstract: | Casein mixed into standard feeds as different ratio of protein,with 35%,40%,45%and 55%, baby-turtle were fed by the standard feeds with these different content of protein. Aftersixty days feeding, the growth rate of baby-turtle fed by the feed with 45%content was thehigh-est among the treatment groups. While fish meal and bean cake were mixed as protein into a kindof feed with 45%protein content,the feed with 59%fish meal and 5?an cake gets gave thehighest growth rate of a baby-turtle.The result showed that baby-turtle had a lower ability of uti-lizing beak-cake protein. |
