A simple, quick and reliable technique of preparing teaser bulls has been developed. Four Bos indicus aged between 1 year 6 months and 2 years were subjected to this method by deflecting their penes backwards about 2 to 3 cm posterior and dorsal to the attachment of the scrotum. No serious postoperative complications were recorded. The sexual behaviour and libido of the bulls did not change after subjecting them to this technique.

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.
