[Method] With Fleckvieh as male parent, they were crossbred with Guizhou local yellow cattle （ ♀ ）, and hybridized cattle of Simmental × local yellow cattle （ ♀ ） to determine production performance, slaughter performance and lactation performance of their offspring. And they were compared with Guizhou local yellow cattle. [ Result ] The growth, slaughter and lactation performance of offspring of F1 Fleckvieh （ ♂ ） × Simmental （ ♂ ） × local yellow cattle （ Q ） proved optimal, followed by offspring of F1 Fleckvieh （ ♂ ） × local yellow cattle （ ♀） and offspring of Guizhou local yellow cattle. [ Conclusion] Offspring of improved local yellow cattle crossbred with Fleckvieh （ ♂ ） and hybridized cattle of Fleckvieh × Simmental × local yellow cattle enjoy significant heterosis and the economic benefits of cattle farming could be significantly enhanced.展开更多

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.展开更多
