摘要
将2127枚波尔山羊胚胎移植给1182只受体,移植单胚、双胚、3胚和4胚时的受体妊娠率分别为60 2%(171/284)、62 7%(540/862)、64 0%(16/25)和54 6%(6/11),胚胎成羔率分别为60 2%(171/284)、51 6%(890/1724)、41 3%(31/75)和36 4%(16/44)。各品种受体移植单胚时妊娠率和胚胎成羔率均无显著差异(P>0 05),移植双胚的奶山羊受体胚胎成羔率显著高于成都麻羊和简阳大耳羊(P<0 05),而南江黄羊低于奶山羊、高于成都麻羊和简阳大耳羊,但差异不显著(P<0 05)。受体羊卵巢上黄体数量对受体妊娠率和胚胎成羔率无明显影响,但随着黄体体积变小,胚胎成羔率逐渐下降。
Boer goat embryos were transferred surgically, when 1,2,3 or 4 embryo were transferred, the pregnancy rates of recipients were 60.2 %(171/284),62.7 %(540/862),64.0 %(16/25) and 54.6 %(6/11), separately, and the rates of embryos developing into kids were 60.2 %(171/284),51.6 %(890/1724),41.3 %(31/75) and 36.4 %(16/44), separately. The pregnancy rates and embryo developing rates were not significantly different among Ya'an Milk Goat, Chengdu Ma Goat, Jianyang Big-ear Goat and Nanjiang Yellow Goat when single embryo per recipient were transferred (P>0.05). When double embryos per recipient were transferred, the pregnancy rate and embryo developing rate of Milk Goat were significantly higher than that of Ma Goat or Big-ear Goat(P<0.05),and the rates of Nanjiang Yellow Goat were higher than that of Ma Goat or Big-ear Goat, and lower than that of Milk Goat, but there were not significantly different (P<0.05). The number of corpus luteum had no significant effect on pregnancy rates and embryo developing rates.
