摘要
取体成熟KM小鼠140只,分别采用一雌一雄长期同居法和短期同居法进行交配繁殖,分别测定第一、二胎仔鼠哺乳期内(1~21日龄)的体重,得到四组数据。经统计分析得出哺乳期内KM小鼠日龄与体重的直线回归方程,回归关系极显著(P<001),绘制了仔鼠生长曲线与日增重曲线。
whole-grown KM mice were taken out, one female lived together with one male for a long or short period separataly. Liveweithtof newborn mice was weithed. The mice xhould be the ist and 2nd littleboth being nursing period(1~21days).4 group data were gothen. Usingstatistical analysis.workedat The line regression equation between daysand liveweight. the regression relation was significant (P<0 01)The babymice growing-up graph and liveweight gain per day were drawn out couldbe treated as bosic data of experiments.
