| 摘 要： | 本研究选用了埋植CIDR栓法、埋植PRID栓法、PG法以及PMSG+PG法四套方案对西藏41头母牦牛进行了超数排卵试验。试验结果:埋植CIDR法得到的平均卵母细胞数为7.4枚/头,埋植PRID法得到的平均卵母细胞数为6.5枚/头,PG法得到的平均卵母细胞数为4枚/头,PMSG+PG法得到的平均卵母细胞数为4.8枚/头,各组之间差异极显著(P<0.01);而经过卵母细胞成熟培养之后,埋植CIDR法得到的平均可用卵母细胞数为6.2枚/头,埋植PRID法得到的平均可用卵母细胞数也为6.2枚/头,PG法得到的平均可用卵母细胞数为4枚/头,PMSG+PG法得到的平均可用卵母细胞数为4.6枚/头,CIDR+FSH法与PRID+FSH法两组、两次PG法与PMSG+PG法两组差异不显著(P>0.05),但是CIDR+FSH法和PRID+FSH法组与两次PG法和PMSG+PG法组之间差异都极显著(P<0.01);用CIDR法和PRID法进行西藏牦牛超排效果较好,并可获得较多的可用卵母细胞。

| Abstract: | The following paper investigates the efficacy of four different reproductive techniques to induce multiple-ovulation in 41 Tibetan yaks.The different treatments used included Controlled Internal Drug Releasing Device(CIDR),Progesterone Releasing Intravaginal Device(PRID),Prostaglandin(PG) injection,and a combination of Pregnant Mare Serum Gonadotrophin and Prostaglandin(PMSG + PG) injection.The average number of oocytes varied significantly between the four treatments(P < 0.01):7.4 with CIDR,6.5 with PRID,4... |
