SUMMARY

Ten mares were used to investigate the effect of adminstration of prostaglandin F on uterine tubal motility, as reflected by embryo recovery from the uterus 5 days after ovulation (day 0). Mares were assigned to 3 groups: group A, uterine flush for embryo recovery on day 7; group B, uterine flush for embryo recovery on day 5; and group C, uterine flush for embryo recovery on day 5, after treatment with prostaglandin F (10 mg, im) on day 3. Each mare was assigned to each group once. Embryo recovery rates for the 3 groups were: A, 6 of 10; B, 2 of 8; and C, 0 of 10. The embryo recovery rate for group C was significantly lower (P < 0.01) than that for group A. Embryo recovery rate for group B was not significantly different from group A or group C. Administration of prostaglandin on day 3 did not increase embryo recovery rate from the uterus on day 5. Additionally, the 25% embryo recovery rate (2 of 8) for group B mares suggested an earlier time for entry of the embryo into the uterus than has previously been reported.
