Sixty lactating Holstein cows were treated, in 3 groups, with Folltropin and Estrumate to induce superovulation and then bred by artificial insemination (AI). Embryos were collected at slaughter on D 4, 5 or 6 after insemination by flushing separately the oviducts, uterine tip and the remainder of the uterine horn. The embryos and ova recovered accounted for 64.6 +/- 4.3% of the ovulations, and there were no differences due to day, side or group. On D 4, 60% of the embryos were found in the oviducts; on Days 5 and 6, 80 and 91%, respectively, were found in the tip of the uterine horn. Viability was independent of the site of recovery; over 91% of the embryos grew and developed in culture for at least 3 d.
