摘　　要：【目的】旨在研究不同促排卵方案对黄牛生产双犊、多犊和活犊数的影响。【方法】将200头杂交黄牛的母牛随机分为4组,A组101头为对照组,常规自然发情后进行人工授精;B、C、D组为试验组,分别采用不同促排方案处理母牛,发情后同样进行人工授精。B组31头,采用CIDR+PMSG+PG+LHRH-A3;C组44头,采用CIDR+FSH+PG+LHRH-A3;D组24头,采用CIDR+IHN+FSH+PG+LHRH-A3。分别统计4种处理方法的受胎率。【结果】A、B、C、D组受胎率分别为68.32%、29.03%、63.64%、66.67%,B组的受胎率比A组显著降低39.29个百分点(P <0.01),C、D组的受胎率与A组相比差异不显著(P>0.05)。在母牛双犊率中,C、D组双犊率与A、B组的差异极其显著(P <0.01);D组比C组提高11.61个百分点,差异显著(P <0.05)。在三犊及以上母牛的占比中,B、C、D组分别极显著高于A组(P <0.01),C、D组极显著高于B组(P <0.01),C组显著高于D组(P <0.05)。C、D组的活产双犊率极显著高于A、B组(P <0.01);B、C、D组的三犊及以上占产活犊总数比例极显著高于A组(P <0.01)。【结论】与对照组相比,采用D方案诱导母牛生产双犊率和活犊的效果最好,其次是C方案,B方案最差。【Objective】The aim of this paper was to study the effects of different ovulation stimulating shemes on the production of double,multiple calves and live calves in yellow cows.【Method】200 crossbred yellow cows were randomly divided into 4 groups,namely group A(101 cows)as the control group,and artificial insemination was performed after routine natural estrus.The cows in groups B,C and D as the test groups were treated with different ovulation induction schemes,and artificial insemination was also performed after estrus.Among them,31 cows in group B were treated with CIDR+PMSG+PG+LHRH-A3,44 cows in group C were cows in group C were treated with CIDR+FSH+PG+LHRH-A3,and 24 cows in group D were created with CIDR+IHN+FSH+PG+LHRH-A3.The conception rates of the four treatment methods were statistically analyzed.【Result】The conception rates of groups A,B,C and D were 68.32%,29.03%,63.64%and 66.67%,respectively.The pregnancy rate of group B was significantly decreased by 39.29 percentage points compared with group A(P<0.01),and the pregnancy rate of group C and D had no significant difference compared with group A(P>0.05).The double calving rate of cows in groups C and D was significantly different from that in groups A and B(P<0.01),and the double calving rate in group D was 11.61 percentage points higher than that in group C(P<0.05).The proportion of cows with three or more calves in groups B,C and D was significantly higher than that in group A(P<0.01).Groups C and D were significantly higher than group B(P<0.01),and group C was significantly higher than group D(P<0.05).The live birth rate of two calves in groups C and D was significantly higher than that in groups A and B,respectively(P<0.01).The proportion of three or more calves in the total number of live calves in groups B,C and D was significantly higher than that in group A(P<0.01).【Conclusion】In conclusion,compared with the control group,D regimen had the best effect on inducing cows to produce double calving rate and live calves,followed by C r
