The Richard C. Wahlstrom Papers contain published articles, research reports, lectures, talks, and related materials documenting Wahlstrom’s extensive work in animal science, particularly in swine nutrition, from the 1950s through the 1990s. The collection includes South Dakota State University publications, journal articles, technical bulletins, conference papers, and photographs that illustrate his research on dietary supplementation, feed efficiency, and animal husbandry practices.

Subjects represented include selenium toxicity and supplementation, the role of vitamins, amino acids, and protein in swine diets, the use of alternative feedstuffs such as oats, alfalfa meal, sunflower meal, and brewers’ grains, and studies on carcass composition and growth performance. The papers also feature experimental studies on antimicrobial use, housing systems, mineral absorption, and the effects of specific feed additives on reproduction and health. In addition to research publications, the collection contains speeches delivered at professional meetings, award citations, departmental newsletters, and correspondence reflecting Wahlstrom’s contributions to the American Society of Animal Science and his recognition as Distinguished Professor of Animal Science.

This collection is a resource of mid- to late-twentieth century animal science research at South Dakota State University. It highlights Wahlstrom’s national reputation as a leader in swine nutrition and his role in shaping scientific understanding of feed efficiency, dietary supplementation, and livestock management practices. The materials provide valuable documentation of SDSU’s contributions to agricultural research and demonstrate the integration of academic inquiry with practical applications in the livestock industry.
