摘　　要：以全脂羊奶粉和婴儿配方牛奶粉为对照,通过体内消化实验和幼龄动物生长实验,测定了婴儿配方羊奶粉中蛋白质的体内消化率,实验组SD大鼠的体重、身长、脏器的重量,奶粉的热能效率、蛋白质功效比及食物利用率。研究结果表明:婴儿配方羊奶粉中蛋白质的体内消化率在灌食后4h时显著高于婴儿配方牛奶粉组和全脂羊奶粉组(p<0.05),最终消化率均达到95%以上;婴儿配方羊奶粉组SD大鼠各内脏器官发育基本正常,实验结束时该组SD大鼠体重和身长分别为216.47g和23.56cm,均显著高于其他两个对照组(p<0.05);婴儿配方羊奶粉的热能效率、蛋白质功效比以及食物利用率分别为3.27g/418.4kJ、1.26和17.03%,各指标均显著高于其他两个对照组(p<0.05)。由此说明,婴儿配方羊奶粉中蛋白质能较快地被机体吸收利用,该奶粉能够有效地促进幼龄动物的生长,具有较高的营养价值。In vivo digestion and juvenile animal growth experiments for goat milk formula powders were conducted, and whole goat milk powders as well as cow milk formula powders was used for comprison./n vivo digestibility of protein,body weight, length, viscera weight of SD rats were measured along with energy efficiency, protein efficiency ratio, food utilization rate of goat milk formula powders.The result showed that in vivo digestibility of protein for goat milk formula powders at 4h after feeding were significantly higher than those of cow milk formula powders and whole goat milk powders （p 〈 0.05）, and in vivo digestion of protein for goat milk formula powders groups were above 95%.Visceral organs of SD rats in goat milk formula powders group developed normally,and body weight and length was 216.47g and 23.56cm respectively in this group,which were significantly higher than those of other two control groups（ p 〈 0.05）.Energy efficiency, protein efficiency ratio, food utilization rate of goat milk formula powders were 3.27g/418.4kJ, ]26 and 1%03% ,aFI of which were much higher than those of other two control groups（p 〈0.05）.Therefore, proteins in goat milk formula could be absorbed easilier, and the goat milk formula powders could effectively promote the growth of young animals.
