应用胚移技术加速安哥拉吐奇代羊繁殖研究

STUDY ON APPLICATION OF EMBRYONIC IMPLANTATION FOR QUICKENING ANGORA GOAT AND DORSET SHEEP REPRODUCE

1986—1989年先后对8头次安哥拉山羊进行超排处理,获得可用胚78枚,平均每头9.75枚;将72枚移给45只陕北黑山羊,有18只妊娠,受胎率40%,怀羔22只.对8头次吐奇代绵羊进行超排处理,获得可用胚45枚,平均每头5.6枚;将42枚移给33只蒙古羊,有10只妊娠,受胎率30%.在我国首次成功的将安拉山哥羊和吐奇代绵羊胚胎移植给土种羊,使两种羊的产羔率分别提高了2.38倍和1.1倍.

Eight Angora goats were handled over ovulation in 1986—1989. From which obtained 78 good embryoes with an average of 9.75 embryoes per goat.72 embryoes were implanted to 45 Shaanbei Black goats, among them 18 Shaanbei Black goats were pregnant with 40% conception rate.45 good embryoes were obtained from eight Dorset sheep handled over ovulation. The 42 embryoes were implanted to 33 Mongolia sheep, in which 10 Mongolia sheep were pregnant with 30% conception rate.The embryoes of Angora goat and Dorset sheep were initiated by implanting to native goats in China. This technique has made the lambing ratio of these goat and sheep being increased 2.38 and 1,1 times respectively.
