中文摘要:

      [目的]小肽营养是蛋白质营养中必不可少的重要组成部分,吸收进入体内后比游离的氨基酸有着更高的利用率,为了促进奶牛产奶量的提高.[方法]选择第2至4个泌乳期体质健康、产奶量相近的荷斯坦奶牛12头,随机分成对照组和试验组,每组6头.对照组饲喂基础日粮,试验组饲喂基础日粮+0.2%的大豆蛋白肽.正试期30 d.[结果]表明,试验组的奶牛平均日产奶量增加了1.32 kg,比对照组提高了5.69%(P＜0.05). [结论]说明小肽营养对提高奶牛产奶量有明显作用.

英文摘要:

      To identify the effects of small peptides on milk yield of dairy cow,12 healthy Holsteins in second to the fourth lactation with similar milk yield were randomly allotted into two groups with 6 cows in each group.The control group were fed basic diet and experimental group were fed basic diet + 0.2% soybean peptide for 30 d.it was showed that the daily milk yield of experimental group increased 1.32 kg,and was 5.69% higher than the group(P<0.05).
