Animal Nutrition and Physiology

Animal nutrition and physiology examines how dietary inputs—amino acids, enzymes, microbial communities, and feed additives—shape the health, growth, and productivity of livestock, with particular attention to species like poultry and swine that sit at the center of global food systems. As the livestock industry moves away from routine antibiotic use, researchers are actively investigating how probiotics and other alternatives can maintain gut integrity, support beneficial microbiota, and preserve production efficiency without contributing to antimicrobial resistance. Environmental stressors like heat further complicate the picture, altering digestion, intestinal barrier function, and nutrient absorption in ways that demand practical, farm-applicable solutions. Open questions include precisely how the gut microbiome mediates the effects of specific feed interventions, and how nutritional strategies can be tailored across production systems to remain effective under real-world conditions.
