A comparative study on the two techniques of uterine flushing in superovulated sheep was conducted. The first method was carried out by flushing of the horn through a Foley catheter inserted into the uterine horn (method I ). The second method involved flushing of the horn with the medium injected into uterine tip nea. the utero-tubal junction through a Foley catheter inserted into uterine horn(method II). Superovulation was carried out on day 8 of the estrous cycle by a FSH-PG method. Ova were flushed on 6 or 7 days after mating. The recovery rates in methods I and II were 68.0%(51/75) and 43.6%(17/39), respectively(p<0.05). It indicated that method I is effective technique for flushing of the sheep ova from the uterus.
