Colonic bacterial community responding to selenium-enriched yeast supplementation associated with improved gut mucus function in growing-finishing pigs.

ABSTRACT: Selenium-enriched yeast (SeY), a high-quality organic source of selenium, enhances antioxidant activity and intestinal health in swine. This study aims to evaluate the effects of varying dietary SeY levels on intestinal morphology, epithelial mucus production, antioxidant activity, and colonic bacterial communities in growing-finishing pigs. Thirty 90-day-old Duroc×Landrace×Yorkshire growing-finishing pigs (average body weight of 54.37±2.13 kg) were randomly assigned to five treatment groups. The control group (CON) was fed a basal diet, while the other four groups were fed the basal diet supplemented with SeY at 0.3, 1, 3, and 5 mg/kg, respectively, for an 80-day of feeding trial. The results showed that the addition of SeY at 0.3 mg/kg increased villus height, villus height/crypt ratio,
