Successful transfer of a bovine embryo through a cannulated fallopian tube.
The fallopian tubes of a recipient cow were surgically cannulated and the cannulae brought out through the flank. Two fertilised eggs, recovered surgically from a donor cow, were transferred to the uterus of the recipient cow through the cannulae. The recipient became pregnant and gave birth to a live normal female calf 289 days after the transfer. After the birth of the calf one cannula was found to be patent.
