【摘要】 为了探求在生产实践中可行、对胚胎损伤较小的切割技术以获得同卵双生后代,研究采用简易显微切割技术和玻璃针透明带内切割技术,分别对山羊桑葚期胚胎进行切割。结果表明,利用显微切割刀进行山羊早期胚胎切割不仅可获得较高的移植产羔率(显微刀简易切割有效率为97.6%,产羔率为55.0%;玻璃针简易切割有效率为96.7%,产羔率为58.3%;玻璃针带内切割有效率为94.4%,产羔率为37.5%),而且不需要精密的显微操作装置,便于在基层生产中推广应用。更多还原

【Abstract】 The study was made to investigate the effects of the biopsy technique of goat embryo.The bisected embryos,which were biopsied using a microblade,had higher rate of goat production than using a microneedle.And it wasn’t need a micromanipulator,so it was easy to apply to grass roots.The effects of the medium with the velvet antler extract also could improved the rate of goat prodution.更多还原
