摘要: 本研究共超排秦川牛31头次,有效超排20头次,有效率为64.5%。头均获胚总数6.45枚,可用胚4.20枚。激素用量为300 mg/头时,头均获胚总数和头均可用胚数显著高于260和340 mg组(P<0.05)。冬春季的头均获胚总数(8.56)和头均可用胚数(6.00)显著高于夏秋季(4.73、2.73)(P<0.05)。对供体牛连续超排处理3次,间隔70 d,对超排效果无显著影响。

Abstract: 31 Qinchuan cattle were superovulated, 20 cattle were effective with the rate 64.5%, and 6.45 embryos were obtained on average. Among them, 4.20 embryos were useful. The embryos obtained from each cattle and useful embryos of the 300 mg group were significantly higher than groups that treated with FSH 260 mg and 340 mg per cattle (P<0.05). The obtained (8.56) and useful embryos (6.00) per cattle treated in spring and summer were significantly higher than that treated in autumn and winter (4.73, 2.73) (P<0.05). 10 cattle were superovulated repeatedly with the interval 70 days. There were not any significantly different between each superovulation (P<0.05).
