Veterinary surgeryIn 1965, the first U.S. surgical operation on a bull to correct a sperm block was performed. The $176,000 Aberdeen-Angus bull, named Linderis Evulse, was owned by the Black Watch Farms, Wappinger Falls, NY. During the operation the animal was strapped on a hydraulic operating table. The veterinarians were Dr. James Hicks and Dr. Donald F. Walker at the Auburn University School of Veterinary Medicine, Auburn, Alabama. The Aberdeen-Angus evolved during the early part of the 19th century from the hardy, black, polled cattle which populated North-East Scotland. George Grant first established the breed in the U.S. with four Angus bulls imported from Scotland to Kansas in 1873. |
