title: Oocyte transfer in mares.
abstract: Oocytes were collected from dominant preovulatory follicles of donor mares 24 hours after administration of human chorionic gonadotropin. Oocytes were incubated in vitro for 12 or 18 hours before transfer to recipient mares, representing maturation times after human chorionic gonadotropin administration of 36 and 42 hours, respectively. Pregnancy rates after transfer were 4 of 5 in the 36-hour group and 2 of 3 in the 42-hour group. The overall pregnancy rate achieved (6/8 mares) indicated that oocyte transfer may be useful clinically.
