College of Ag Faculty Publishes Research in Journal of Animal Science

East Texas A&M University Assistant Professor Landon Sullivan was recently published in the latest issue of the Journal of Animal Science. Sullivan’s research, titled “Mitigation of oxidative stress to improve range cow grazing distribution,” was co-authored with faculty from the University of Idaho, Iowa State University, South Dakota State University and the University of Connecticut.

Sullivan has taught at East Texas A&M since 2022 and educates students in Animal Science, Equine Studies and Veterinary Tech courses.

The study’s purpose was to discover if an injectable trace mineral could reduce oxidative stress and improve grazing distribution among cattle. Oxidative stress is an imbalance of free radicals and antioxidants in the body that leads to cell damage. In humans, it plays a role in many conditions like cancer, Alzheimer's disease and heart disease. In cattle, it causes uncontrolled cell death, tissue damage and malignant cell development that can progress to states of disease.

The study’s results indicated that implementing injectable trace minerals mitigated indicators of oxidative stress and improved cow foraging on western rangeland in two consecutive summers.

Published by the American Society of Animal Science, the Journal of Animal Science touts itself as the premier journal and leading source of new knowledge and perspectives in the field of animal science. Sullivan’s research was featured in Volume 103.
