Gonadotropin effects in order to induce polyovulation were studied. Polyovulation schedule which provides induction of polyovulation in not less than 80-100% of donors is given, each donor ovulating on the overage 9,28 +/- 1,03 follicles. Method of extracting emryos is described. It was develobed in Kazakh Research Institute of Sheep Breeding and allows to wash out up to 91% of embryos from all ovulated follicles. The advantage of this method is that the system for washing donor uterus parts is simple and tight. Embryo acceptability is observed to depend on many factors including synchronous estrus of donor and recipients, number of inseminated ovicells, condition of endometrium and recipient yellow bodies. Level of acceptability varies from 45% to 70% depending on factors being studied (according to lambing records).
