To study strategies that minimize the use of antibiotics in monogastric livestock production, while maintaining the animal’s welfare and performance, in order to reduce the risk of antimicrobial resistance development. This key focus area will be pursued by conducting studies on:

• Gut microbiome composition and function and how it is affected by host-related (e.g., age, genetics, sex) and external (e.g., diet, environment, weaning, stress) factors.
• The impact of feed additives and feed ingredients, like pre- and probiotics, compounds with antimicrobial activities, ingredients with functional constituents, alternative protein sources, and feeding strategies like fermentation, on gut microbiome, gut function, and the animal’s immune response.
