| 摘 要： | 后备奶牛的培育是养牛生产中的一个重要环节,后备奶牛阶段正值生长发育旺期,发育程度的好坏直接影响成年奶牛的体形、体况、健康、繁殖以及产奶性能。因此,通过对后备奶牛生长发育状况的分析,可了解后备奶牛各阶段的营养需要水平及生长发育水平,为科学的饲养管理提供理论依据。

| Abstract: | Replacement heifers cultivation was an important part of dairy cattle production. During growth stages,the developmental degree of replacement heifer affected directly adult cow of the body type,body condition,health,reproduction and milk performance. By analyzing the growth character of replacement heifers,the nutrient requirements in different growing stages could been known, which provided theoretical basis on scientific breeding and management . |
