Area of Expertise: Stress and Nutritional Physiology

Research Goal and Philosophy: The overall goal of Dr. Johnson's research program is to evaluate the impact of environmental (i.e., heat stress) and production stress on livestock physiology, welfare, and metabolic health to develop mitigation strategies that will improve animal well-being and productivity. Climate models predict an increase in the frequency of heat waves and temperature extremes in regions where animal agriculture is prevalent. In addition, livestock producers, consumers, and scientists are concerned about the effects of stressors that animals are exposed to. Therefore, there is a continuous need for scientists and producers to improve upon or develop new livestock management practices that either reduce or eliminate the negative effects of stress.
His research program is designed to meet the goals by providing information about the effects of stress on livestock and developing management and nutritionally based mitigation strategies and recovery methods that can be used to improve animal well-being and productivity.
