| 摘 要： | 在奶牛业长期发展和选育过程中,对奶牛单产的片面追求,导致奶成分比例降低,牛群健康、繁殖等次级性状下降。因此提高群体的综合生产性能及经济效益已成为目前奶牛生产的首要问题。杂交繁育能够结合不同品种的优点、利用杂种优势,提高奶牛群总体经济效益,因而备受奶牛业的关注。本文从不同重要经济性状角度介绍了奶业发达国家对奶牛杂交繁育的研究结果,并探讨了奶牛杂交繁育体系在我国的应用。

| Abstract: | Unilaterally pursuing milk yield has lead to decreased milk component concentration,and declined health status and fertility efficiency in dairy industry worldwide.To improve the total production efficiency and profitability nowadays becomes ultimate goal in dairy breeding and dairy production.Crossbreeding system is well-known for taking advantage of breed complementarities and heterosis.Recent 20 years crossbreeding system has been studied and practiced to improve the milk component and secondary traits,s... |
