为探讨南阳牛的同期发情和超数排卵方案，采用1次氯前列烯醇（PG ）法、2次PG法、孕激素阴道栓（CIDR）＋PG法3种同期发情方法，PG＋垂体促卵泡素（FSH）和CIDR＋FSH＋PG法2种超排方案对南阳牛进行处理，FS H剂量分别采用270、300、330 mg/头，研究不同药物、方法、剂量对南阳牛同期发情率和超排效果的影响。结果显示，CIDR＋PG法、2次PG法处理的同期发情率较高，分别显著高于1次PG处理38.26、35.30个百分点；用PG＋FS H法和CIDR＋FS H＋PG法对南阳牛进行超排处理的头均黄体数、头均获胚总数和头均可用胚数均无显著差异；300 mg/头 FSH剂量组的育成牛头均可用胚数显著高于270、330 m g/头剂量组；330 m g/头剂量组的经产牛头均可用胚数显著高于270、330 mg/头剂量组。表明，南阳牛比较适宜的同期发情方案为CIDR＋ PG 法和2次PG法，超数排卵方案为PG＋FSH和CIDR＋FSH＋PG法，FSH的适宜剂量为育成牛300 mg/头、经产牛330 m g/头。

To discourse the effect of different medicines and treatments on the synchronization of estrus and superovulation ,three methods of synchronization of estrus (single treatment with PG , double treatment with PG ,CIDR+PG) and two superovulation plans(PG+ FSH ,CIDR+ FSH+PG) were used with 270 ,300 ,330 mg FSH on the Nanyang cattle in this research ,respectively . The results showed that :The synchronization of estrus rate of the double treatment with PG group and the combination CIDR with PG group were higher than the single treatment with PG group by 38.26 and 35.30 percenge points ;There were no significant difference of the corpus lu-teum ,picking embryo and available embryos after Nanyang cattles were superovulated with PG +FSH method and CIDR+FSH+PG method ,respectively .The effect on the delivered female cattle was slightly better than the heifer ,but the difference was not significant ;The available embryos of the treatment with 300 mg FSH group was significant higher than the group of the 270 mg and 330 mg group in young cattle heifer ,and the treatment with 330 mg FSH group was significant higher than the group of the 270 mg and 300 mg group in delivered cattle .The research shows that the better plan of the Nanyang cattle estrus synchronizationembryo is CIDR +PG and double treatment with PG ,superovulation is PG + FSH and CIDR+ FSH+ PG ;The proper dose of the FSH for the delivered cattle is 330 mg ,300 mg for heifer .
