The objective of this project was to produce multiple pregnant recipient mares during one year from each of four mares which were in athletic training and competition. Twenty-six embryos were recovered from the four mares in 38 collection attempts. Each embryo was surgically transferred to one of 20 recipient mares. Nine of 10 recipient mares which were transferred to on one occasion were detected pregnant at the one week post transfer pregnancy examination and six of eight mares which were transferred to on two occasions were detected pregnant at one of the one-week post transfer pregnancy examinations. Three of the 15 pregnant recipient mares lost their pregnancies by day 150. The 12 resulting pregnant recipient mares from the four competing donor mares demonstrated that donor mares can remain in athletic competition and at the same time provide viable embryos for embryo transfer.
该项目的目标是在一年时间里，从四匹处于运动训练和比赛状态的母马中，让每匹母马都孕育多胎受体母马。在38次采集尝试中，从这四匹母马身上获取了26个胚胎。每个胚胎都通过手术移植到20匹受体母马中的一匹体内。一次接受移植的10匹受体母马中有9匹在移植后一周的妊娠检查中被检测出怀孕，两次接受移植的8匹母马中有6匹在其中一次移植后一周的妊娠检查中被检测出怀孕。15匹怀孕的受体母马中有3匹在第150天时流产。来自四匹参赛供体母马的12匹受体母马成功怀孕表明，供体母马可以继续参加体育比赛，同时为胚胎移植提供 viable 胚胎。 （注：此处“viable”未找到更合适的准确医学术语，暂保留英文）
