为探索适合草原放牧条件下西门塔尔牛的超数排卵技术,分别采用国产及进口促卵泡素(FSH)和三种方案(A:FSH+ PG; B:FSH+ PG+GnRH; C:FSH+ PG+ CIDR +GnRH)对放牧条件下西门塔尔牛进行超数排卵试验.结果表明,采用国产FSH超排时,方案A、方案B和方案C所获头均可用胚数分别为(3.43±2.41)枚、(5.93±3.54)枚和(7.21士3.19)枚,采用进口FSH超排时,三种超排方案所获头均可用胚数分别为(4.34±2.71)枚、(6.76±3.79)枚和(7.79士4.23)枚,采用两种FSH超排,方案B、方案C所获头均可用胚数明显高于方案A(P＜0.05)；3种方案中,国产与进口FSH所获头均可用胚数差异均不显著(P＞0.05).试验表明,在放牧条件下,采用三种超排处理方案,以FSH+ PG+ CIDR+ GnRH法最好,FSH+PG+ GnRH法次之,FSH+PG法效果最差:国产FSH与进口FSH超排效果差异不显著.
