Intra- and inter-breed transplantations were carried out with Bulgarian fresh embryos and with frozen embryos imported from Poland. A complex biotechnology was worked out, including methods of estrus synchronization, of inducing superovulation, and of producing, morphologic evaluation, storing, and transplantation of sheep embryos. Discussed are the possibilities of using embryo transplantation in sheep breeding for the fuller use of the reproductive potential of elite ewes as donors of embryos, for the introduction of new genotypes by means of importing frozen embryos as well as a modern model for fundamental investigations in the reproductive and cell biology.
利用保加利亚新鲜胚胎以及从波兰进口的冷冻胚胎进行了品种内和品种间的移植。制定了一套复杂的生物技术，包括发情同步化、诱导超排卵以及绵羊胚胎的生产、形态学评估、储存和移植方法。讨论了在绵羊育种中使用胚胎移植的可能性，以便更充分地利用优良母羊作为胚胎供体的繁殖潜力，通过进口冷冻胚胎引入新基因型，以及作为生殖和细胞生物学基础研究的现代模型。
