肉用种母牛产犊配种间隔及影响因素

Beef Cattle’s Calving Interval and Affecting Factors

通过对肉用种母牛产犊配种间隔的研究发现，产犊配种间隔与肉种牛膘情有关（Ｐ＜０．０５）。与季节有关，与样本总体比，十二月份差异极显著（Ｐ＜０．０１），十一月份较显著（Ｐ＜０．０５）。与品种和胎次无关。

This paper discusses the study on mating interval of beef cattle’s calving.Results show that mating interval has relation with the cow’s fatness(P<0.05)and seasons,differences are very remarkable in December(P<0.01) and less in November(P<0.05)and has no relation with breed and births.
