Understanding the Interaction Between Nutrition and Swine Health

Adequate intake of essential nutrients is crucial to maintain good health of swine. Animals fed properly are more resistant to many bacterial and parasitic infections, partially due to improved digestive tract capacity, nutrient digestibility, tissue integrity, increased immunological resistance to diseases or fast recovery from them, increased antibody production and increased well-being. Nutrient utilization can only be optimized if pigs have high health status which increases productivity, efficiency, and also nutrient requirements. Therefore, diet and health are intricately connected and interdependent.

The objective of this Research Topic is to publish research articles, short communications and reviews that focus on factors affecting swine’s gastrointestinal physiology, nutrition, welfare and health.

The Guest Editors encourage submissions about traditional aspects of swine production, including, but not limited to:
- Nutrition and gut physiology
- Factors influencing changes in gut microbiome
- Nutritional effects from immunological stress
- Impact of management and housing on health and welfare are also welcome

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Sarah Pearce, Research Animal Physiologist with USDA ARS, explains why stress can act as a nutrient thief in pigs. She discusses gastrointestinal health, barrier integrity, inflammation, feed efficiency, stress interactions, and emerging biomarkers that may help predict performance challenges before they occur.

"Stress can steal calories and nutrients because energy normally used for growth is redirected toward immune activation, gut repair, and other costly survival responses."
