摘要 采用国产促性腺激素对新西兰白兔进行超数排卵试验,研究激素、季节及兔龄对超排效果的影响。结果发现:①FSH组(30.05±8.97个/只)平均排卵数显著高于PMSG组(22.46±5.18个/只)(P<0.05)。②母兔在春季、夏季、秋季、冬季的平均排卵数为32.34±5.58、15.96±4.11、24.18±4.95和22.61±3.75个/只,春季的处理效果显著优于其他3个季节(P<0.05),而秋季和冬季处理组之间没有显著差异(P>0.05),但都显著高于夏季(P<0.05)。③经产母兔超排处理后的平均排卵数(30.56±6.79个/只)显著高于青年母兔平均排卵数(21.60±3.66个/只)(P<0.05)。以上结果表明,SH超排效果优于PMSG,且在春季对母兔进行超排处理比较合适,经产母兔比青年母兔超排效果更好。 The effect factors of the superovulation in rabbit were investigated in this study.The results showed: ①The average number of oocytes recovered from FSH-treated group(30.05±8.97) was significantly higher than PMSG-treated group(22.46±5.18)(P0.05).② When the superovulation was conducted in seasons of Spring,Summer,Autumn and Winter,the number of recovered oocytes were 32.34±5.58,15.96±4.11,24.18±4.95 and 22.61±3.75,respectively,the number of recovered oocytes of the treatment group in Spring was higher than that of the other three groups(P0.05),and there were no difference between Autumn and Winter groups(P0.05),but both of them were higher than Summer group(P0.05).③ The average number of oocytes recovered from superovulation in pluriparous rabbit group(30.56±6.79) was higher than young rabbit group(21.60±3.66)(P0.05).These results indicated that the effect of FSH on superovulation in rabbit was more effective than PMSG,and the season of spring and pluriparous rabbit were comparatively suitable for superovulation.
