	1	Study on Reproductive Performance of Improved Hybrid from Chinese Holstein Cattle显示文摘In order to overcome the problems such as decline in adaptability,low fertility and few utilization years due to continuously increasing coefficient of inbreeding of Chinese Holstein cattle,three dairy-beef dual-purpose cattle varieties( purebred Simmental,Montbeliard and Fleckvieh) were introduced as the male parents to be hybridized with Chinese Holstein cattle,so as to study the improvement effect in the reproduction performance and milk production performance of the hybrid cattle. The results showed that the first-filial generation of Montbeliard had a very significant difference in gestation period from Chinese Holstein cattle( P <0. 01). The parity of Fleckvieh's first-filial generation had a very significant effect on 305 d milk yield( P <0. 01); and for the first-filial generation of Montbeliard,mating times and open days significantly affected 305 d milk yield( P < 0. 05),and its total milk yield had a significant difference from Chinese Holstein cattle( P < 0. 05). Comprehensively,the reproduction traits of Montbeliard's first-filial generation are better than other two varieties.
