【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。更多还原

【Abstract】 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)(P<0.05).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(P<0.05),and there were no difference between Autumn and Winter groups(P>0.05),but both of them were higher than Summer group(P<0.05).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)(P<0.05).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.更多还原
