实验采用三种代乳粉,即A方含全脂牛奶粉17.5％,B方与C方各含大豆30％与26％;A与B方均含蔗糖22％,C方不含蔗糖;其他成分为稻米粉,蛋黄粉(少量),豆油及其他成分,分别喂养一月龄雄性大鼠共4周。结果表明,C方促进大鼠生长效果最好,体重增重,FE、CE、及每克蛋白质增加体重克数均明显高于A方与B方,但B方与A方相似。大鼠体重恢复试验也以C方明显优于A方与B方。氮平衡、生物价三组间差异不显著。含蔗糖22％喂养大鼠4周,对大鼠血清渗透压未有明显影响。
The experimental use of three kinds of milk replacer, that is, A side with whole milk powder 17.5%, B side and C side containing soybeans 30% and 26%; A and B parties contain sucrose 22%, C side without sucrose; other components Rice flour, egg yolk powder (a small amount), soybean oil and other ingredients, were fed a one-month-old male rats for 4 weeks. The results showed that C-induced growth was the best in rats. Body weight gain, FE, CE, and weight gain per gram of protein were significantly higher than those of A and B, but B and A were similar. Body weight recovery test was also significantly better than the C side A side and B side. Nitrogen balance, biological price difference between the three groups was not significant. 22% of rats fed with sucrose for 4 weeks had no significant effect on serum osmolality in rats.
