Dr. Southwell was the first Animal Husbandsman employed at CPES. He assembled the original dairy, beef and swine herds which were the basis for the station's highly successful livestock research programs. Under his guidance, the Animal Science Department grew to six scientists.
Dr. Southwell established animal genetic improvement programs in beef, dairy and swine. He began performance testing programs with Polled Hereford cattle in 1938, with one of the oldest herds in the U.S. on which such records were kept. He was primarily responsible for establishment of swine and beef testing stations, leading to genetic improvement of livestock for farmers across the state and Southeastern United States.
