Biography

Kara Thornton-Kurth is an Assistant Professor in the Animal, Dairy and Veterinary Sciences Department at Utah State University. In 2009, she earned her B.S. in Honors Animal Science and a minor in Spanish from Washington State University. She then moved eight miles across the border and completed her doctoral studies in skeletal muscle physiology at the University of Idaho in 2013. Next, Dr. Thornton-Kurth worked as a post-doctoral research associate at University of Minnesota, where she received additional training in skeletal muscle growth. In 2015, she joined USU faculty and runs a research program focusing on the effects of nutrition and growth in livestock animals.

Teaching Interests

Dr. Thornton Kurth currently teaches four separate courses: 1. Animal Feeds & Feeding (ADVS 2500) 2. Applied Animal Nutrition (ADVS 5500/6500) 3. Nutrient Utilization and Metabolization in Livestock (ADVS 5530/6530) and 4. Basic Nutrition (VM7580).

Research Interests

Research in Dr. Thornton-Kurth's lab broadly focuses on improving production and efficiency of livestock animals, particularly brief cattle. A major goal of Dr. Thornton-Kurth's research program is to uncover the molecular mechanism(s) through which nutrition affects growth and end-product quality of livestock animals. Currently, there are 5 projects occurring in her lab:
1. Determining the molecular mechanisms through which anabolic implants improve skeletal muscle growth of beef cattle
2. Analyzing the impacts of bovine maternal nutrition on growth of progeny skeletal muscle
3. Understanding the molecular factors responsible for development of tenderness in beef products
4. Determining whether testosterone treatment improves growth of skeletal muscle through modulation of the polyamine biosynthetic pathway
5. Develop strategies for beef producers that receive mineral deficient cattle into their feedlots
Dr. Thornton-Kurth's research program is currently supported by funds from the Utah Agricultural Experiment Station, the United States Department of Agriculture, the Western Sustainable and Research and Education Programs, as well private industry funding.
