摘要: 选择0~6月龄的纯种巴音布鲁克羊羔羊和巴音布鲁克羊经济杂交羔羊,在自然放牧状态下,观察羔羊生长规律及经济杂交效果。通过对母羊妊娠后期进行补饲,研究补饲对羔羊产后生长的影响。结果表明,巴音布鲁克羊从出生到6月龄的过程中,2~3月龄增长最快,其次是1~2月龄、0~1月龄;4~5月龄体重下降,5~6月龄又开始增加。妊娠后期母羊补饲对羔羊产后生长没有明显影响,经济杂交羔羊杂交优势明显,公、母羔羊累计生长体重均极显著高于纯种巴音布鲁克羔羊。所以根据羔羊生长规律,加强羔羊生长高峰期营养和管理,是提高巴音布鲁克羊经济效益的重要措施。

Abstract: Under grazing condition, some Bayinbuluk sheep and its crossbred with Dorset were selected as subject, observe their growth from birth to six months old. In addition, observe effect of supplement of pregnant ewe on their lambs. Results showed that maximum growth is from 2 to 3 months, then from 1 to 2 months, 0 to 1 months. The body weight decreased from 4 to 5 months.Then increased from 5 to 6 months. Supplement to pregnant ewe has not effect on their lambs. Significant advantage on growth of crossbred of Dorset and Bayinbuluk sheep can be observed.
