- Beef cattle breeding research was conducted in the early 1940's in cooperation with Fort Lewis A&M.
- In 1946 many of the foundation lines of the present cow herd were established.
- Early research centered on the development of inbred lines of Hereford cattle and subsequent line crossing among lines.
- Selection for improved breeding values for economic traits was practiced concurrently.
- Studying the effects of inbreeding on reproduction and growth traits was practiced concurrently.
Dr. Stonaker was a fresh Ph.D from Iowa State University when he was hired by Colorado A & M (now CSU) Department of Animal Science in 1943. With a degree in Animal Breeding and Genetics under Dr. J.L. Lush, he began looking at the resources and facilities at the "old fort". After a brief stint serving his country, he returned in 1946 to begin one of the largest and longest running project to study inbreeding in cattle.
This picture of Dr. Stonaker was taken in late 1940s. In June, 1998 he identified this bull as Hiwan Prince C58, one of the comprest bulls in the Mesa line.
