This is the first report of an acephalous lamb from the transfer of an in vitro-produced sheep embryo. Twelve in vitro-fertilized embryos were transferred to 4 recipient ewes (3 embryos/ewe). Two ewes remained pregnant: one delivered a normal female lamb, the other a male acephalous lamb. Possible contributing factors are discussed.
这是首例关于体外生产的绵羊胚胎移植产出无头羔羊的报告。将12个体外受精胚胎移植到4只受体母羊体内（每只母羊移植3个胚胎）。两只母羊怀孕：一只产下一只正常的雌性羔羊，另一只产下一只雄性无头羔羊。文中讨论了可能的促成因素。
