Cover Story: Gut health is vital for pig productivity and welfare. However, the use of antimicrobial growth promoters (AGPs) has contributed to rising antimicrobial resistance, a growing public health concern. A review by Lee et al. explores the use of prebiotic galacto-oligosaccharide (GOS) and xylo-oligosaccharide (XOS) in promoting health and as alternatives to AGPs in pig production. These non-digestible carbohydrates reach the hindgut intact, where they stimulate beneficial short-chain fatty acid-producing microbiota (including Lactobacillus and Bifidobacterium), enhance microbial diversity, suppress enteric pathogens including rotaviruses, modulate immune responses, strengthen gut barrier function, and improve nutrient absorption. When used at appropriate developmental stages, GOS and XOS function as effective feed additives to support gut health, productivity, and animal welfare. View this paper
