| 摘 要： | 本文从猪胚胎的体外成熟和体内成熟两方面对显微注射用猪胚胎的获取进行了初步研究。实验结果表明 ;超数排卵母猪的手术冲胚是获取显微注射用猪胚胎的最佳方法 ,该方法获得的胚胎数量多 ,质量好 ,转基因效率高。体外成熟法获得可供显微注射用猪胚胎的效率低 ,基因转移的总效率也很低。

| Abstract: | Maturation in vitro and in vivo are two ways to prepared pig embryos for microinjection.Maturation in vitro includes oocyte maturation culture and fertilization;and maturation in vivo is a method of getting embryos directly from natural and superovulation sows. Experiment results indicated that obtaining embryos from superovulation sows by operation is the best way to get more and better embryos, and the gene transfer efficiency is higher. On the contrary, the efficiency of preparation embryos for microinjection by maturation in vitro is low, and the efficiency of gene transfer is low too. |
