摘要： 采用FSH共超排南阳牛60头次，共采卵258枚（头均4.87±3.69），其中可用胚153枚（头均2.89±2.58），育成牛超排反应有效率高于经产牛（86.2% ︰71.0%），经产牛采卵数多于育成牛（头均5.22±4.53 ︰头均4.5±2.58），可用胚数也多于育成牛(头均3.07±3.06 ︰头均2.69±2.02)，FSH的适宜剂量经产牛为340mg/头，育成牛为300mg/头。季节对南阳牛超排没有明显影响。

Abstract: Sixty donor cows were superovulated with FSH, 258 eggs (4.87±3.69 eggs per head) were collected with 153(2.89±2.58 eggs per head) useful embryos. The superovulation efficiency of heifers is higher than that of the delivered cows（86.2%︰71.0%）, while it was conversed for the total eggs（4.50±2.58︰5.22±4.53） and useful embryos（2.69±2.02︰3.07±3.06）. The suitable doze of FSH is 340mg per head for delivered cows, for the heifers is 300mg. And the seasons have little effect on the superovulation result.
