SUCCESSFUL TRANSFER OF A FERTILIZED BOVINE EGG BY NON-SURGICAL TECHNIQUES

Abstract

Summary. Two fertilized eggs, recovered from two gonadotrophintreated Holstein heifers 4 and 6 days after ovulation, were transferred to the uteri of two synchronized recipient heifers by means of non-surgical techniques. A specially designed apparatus was used for the transfer. Both recipients became pregnant and one gave birth to a normal bull calf after 268 days. It was established by blood-typing that the calf had developed from a transferred embryo. The other recipient aborted on the 80th day of pregnancy.
