In this study embryo recovery from oviduct and uterus of superovulated sheep was performed in two different herds. An endoscopic technique was established, which allows a combined flushing of the oviduct and the uterus. 29 animals were used for flushing of tubal stage embryos and 36% of the oocytes/embryos were collected. Embryo flushing of uterine stages was performed 4, 5 and 6 days after estrous. In 34 donor ewes the finding rate was 26%. Taking into consideration that 63% of the donor ewes showed large persisting follicles the results show that this is a suitable technique for an effective embryo recovery from uterus and oviduct.
