摘　　要：为探讨影响新疆地区西门塔尔母牛情期受胎率的因素,本试验采用SAS 8.1对影响情期受胎率的配种季节、与配公牛和母牛年龄3个因素进行最小二乘方差分析,各水平间进行Duncan多重比较并分析不同水平对情期受胎率的影响。结果表明,不同配种季节对西门塔尔母牛情期受胎率影响极显著(P<0.01),春季西门塔尔母牛情期受胎率极显著低于夏季、秋季、冬季(P<0.01),冬季情期受胎率最高(64.7%),而春季情期受胎率最低(40.0%);与配公牛对西门塔尔母牛情期受胎率无显著影响(P>0.05);母牛年龄对西门塔尔母牛情期受胎率的影响极显著(P<0.01),随着母牛年龄的逐渐增加情期受胎率有降低的趋势。依据本研究结果,可针对各影响因素合理有效的调控,从而提高母牛的情期受胎率,最终提高牛场经济效益。In order to explore the factors of investigate the conception rate on Xinjiang region Simmental cows.The effects on conception rate were analyzed by SAS 8.1GLM,between the different effect levels by Duncan multiple comparison and analysis its effect on estrus conception rate.The results showed that different breeding season pregnancy rate of Simmental cows had significant effects（P0.01）,the pregnancy rate in spring was significantly lower than summer,autumn and winter conception rate on Simmental cow（P0.01）,the highest pregnancy rate in winter（64.7%）,pregnancy rate lowest in spring（40.0%）;Of Simmental bulls and cows with conception rate had no significant effect（P〉0.05）;Cow age on pregnancy rate of Simmental cows had significant effects（P0.01）,and with increasing age,pregnancy rate of dams has decreased.In this paper,a large number of records information on factors affecting pregnancy rate of Simmental cows for analysis,which will help to improve the pregnancy rate of dams,and ultimately improve the economic efficiency of cattle.
