University of Tokyo opened its own farm one year before I finished my three-year research in the field of livestock surgery. And I was assigned, as the status of a research student, to look after the livestock in the new farm. As a veterinarian, I was also expected to extend support for reproduction of foreign-based brown haired wagyu via artificial insemination. The farm's budget was fixed as 70% of the income earned in the previous year. Obviously there was no budget to purchase thoroughbred at this farm. So I proposed a barter deal of giving Arab horse belonging to our farm and receiving a 23-year-old thoroughbred that had a record of two miscarriages in the Goryo Farm. Despite great concerns, the thoroughbred gave birth to a filly in March 2nd, 1964. The same year, we received another imported mare that had jaundice, and got a foal. Subsequently, we got a mare which was not pregnant for nine years from a private farm. Sure enough that was another successful case of giving birth to a foal. Some of these foals ended up participating in thoroughbred stakes like Oka-Sho, Satsuki-Sho and Derby races. Positive administration of hormones was the key to the success. However, none of those hormones are sold today due to various potential dangers. The field of reproduction learned through such experience still remains as part of my treasure.
