Non-Surgical Recovery of Equine Eggs, and an Attempt at Non-Surgical Egg Transfer in Horses

Summary. Equine ova were successfully recovered non-surgically from the uterine lumen using a three-way system apparatus. The recovery rate was 45%. Ova collected from the uterus were in the blastocyst stage. The transfer of rabbit ova into the uterine lumen of a mare through the cervix hastened the transport of the fertilized equine ovum in the uterine tube. Equine ovum transfers were performed in eleven recipient mares 5 to 7 days after ovulation without success. It was clearly noted that uterine flushing in the dioestrous mare affected the time of the next ovulation.
