作者设计了粗蛋白质含量分别为23.2％、21.1％、17.7％三种饲料配方。将3周龄KM小鼠60只,分为3组,每组20只,分别饲喂3种不同蛋白质水平的饲料,观察各组KM小鼠生长、繁殖情况及脏器重量系数。结果显示:处于生长发育高峰期的4～5周龄鼠,高蛋白组的体重及日增重极显著高于其它2组(P<0.01)。不同蛋白质水平的饲料对KM小鼠的繁殖性能和脏器重量系数影响明显,各组生育综合指数和内脏综合系数的高低与日粮蛋白质水平成正比。
The author designed the crude protein content of 23.2%, 21.1%, 17.7% of the three feed formulations. Sixty three-week-old KM mice were divided into three groups with 20 mice in each group. The mice were fed with 3 different protein levels of feed. The growth and reproduction of KM mice and organ weight coefficient were observed. The results showed that body weight and daily gain of 4 and 5 weeks old rats in the peak of growth and development were significantly higher than those in the other two groups (P <0.01). Different protein levels of feed on KM mice reproductive performance and organ weight coefficient significantly affected, each group fertility index and visceral integrated coefficient of the level of dietary protein level is proportional to.
