摘　　要：用４组药物组合：（１）ＰＭＳＧ＋ＰＧＦ２ａ；（２）ＰＭＳＧ＋ＰＧＦ２ａ＋激光照射；（３）ＦＳＨ＋ＰＧＦ２ａ；（４）ＦＳＨ＋Ｃｔｏｐｒｏｓｔｅｎｏｌ，超排处理３２２头次供体牛。共采卵１６６３枚（头均５．８１±４．６８），可用胚胎９８０枚（头均３．４３±３．９４，占５８．９％）。（３）、（４）两组胚胎可用率及可用胚胎数高于（１）、（２）组（ｐ＜０．０５）；黄牛胚胎可用率高于奶牛（ｐ＜０．０１）；育成牛胚胎可用率高于经产牛（ｐ＜０．０１）；供体牛前两次超排效果更好（ｐ＜０．０５）。head-time donor cattle were superovulated with 4 medical combination treatment including (1) PMSG+PGF 2a , (2) PMSG+PGF 2a +laser irridiation, (3)FSH+PGF 2a and (4)FSH+Cloprostenol. 1 663 eggs (5.81±4.68 per head) were obtained with available embryoes of 980 (3.43±3.93 per head), that accounted for 58.9% of the total. The available embryo number and rate of group (3) and were higher than that of group (1) and (2) (p<0.05); available embryo rate of yellow cattle and heifers were higher than that of dairy cattle and multipara cows respectively (p<0.01); donor cattle showed the better results in the first and second superovulation treatment.
