摘　　要：【目的】探讨各因素对新疆地区荷斯坦奶牛产犊间隔的影响。【方法】采用SAS8.1软件对影响产犊间隔因素进行最小二乘方差分析。【结果】不同场地对产犊间隔的影响不显著(P>0.05);不同胎次对产犊间隔有显著影响(P<0.05),产犊间隔随胎次增加有延长的趋势;不同产犊季节对产犊间隔有极显著影响(P<0.01),冬春季节产犊间隔明显高于夏秋季节;不同产奶量对产犊间隔有极显著影响(P<0.01),产犊间隔随着产奶量的增加而延长。【结论】产犊季节和产奶量是影响产犊间隔主要因素。[Objective]In order to investigate factors influencing calving interval of Holstein in Xinjiang area.[Method]The effects on calving interval were analyzed by SAS8.1 GLM.[Result]Effect of different farms on calving interval was not significant （P〉 0.05）;Effect of different parities on calving interval was significant （P〈 0.05）,the calving interval increased with the parity increased;effect of calving season on calving interval was highly significant （P 〈0.01）,calving interval in spring and winter were much longer than that in summer and autumn;effect of different milk yield on calving interval was highly significant （P 〈0.01）,the calving interval prolonged with the milk yield increased.[Conclusion]Calving season and milk yield were the main factors influencing calving interval.
