Embryos collected from ewes on days 5, 6 and 7 after oestrus were transferred to synchronised recipient ewes by a simple laparoscopic technique which resulted in a pregnancy rate of 75 per cent. The reduced surgical trauma and operative time have benefits in terms of animal welfare as well as for the economics of the embryo transfer industry.
在发情后第5、6和7天从母羊采集的胚胎，通过一种简单的腹腔镜技术移植到同期发情的受体母羊体内，妊娠率达75%。手术创伤和手术时间的减少对动物福利以及胚胎移植行业的经济效益都有好处。
