摘　　要：用ＦＳＨ＋ＰＧＦ１。超排处理７２头次供体牛，采卵３６１枚（头均６．５１±３．８２），可用胚２３５枚（头均３．２６±３．４７）。黄牛胚胎可用率高于奶牛、肉牛（Ｐ＜０．０１），育成牛胚胎可用用率高于经产牛（Ｐ＜０．０１），秋冬季超排效果明显好于春季（Ｐ＜０．０１）。Seventy-two donor cows were superovulated with FSH + PGF 2α , 361 eggs (5.51±3.82 eggs per head) were collected with 235 (3.26±3.47 eggs per head) eggs for embryo transfer. The available embryo percentage of yellow cattle was greater than dairy and beef cows (P < 0.01), the superovulation result in fall and winter time was better than in spring (P < 0.01).
