Exploring the potential of mannan oligosaccharides in enhancing animal growth, immunity, and overall health: A review

Abstract

The growing demand for sustainable and efficient animal husbandry has driven significant interest in dietary supplements that enhance growth performance, immunity, and overall health. This review explores the promising potential of mannan oligosaccharides (MOS) as a functional dietary supplement in animal nutrition. Derived from yeast cell walls, MOS have garnered attention due to their prebiotic properties, which positively influence gut health by promoting beneficial microbiota and inhibiting pathogenic bacteria. Numerous studies demonstrate that MOS supplementation leads to improved growth rates, enhanced immune responses, and better nutrient utilization in various animal species, including poultry, swine, and aquaculture. This review synthesizes current research findings, highlighting beneficial effects of MOS such as modulating gut microbiota, enhancing intestinal morphology, and stimulating the immune system. Additionally, the review addresses the practical applications, optimal dosages, and potential challenges of incorporating MOS into animal diets. By elucidating the multifaceted benefits of MOS, this review underscores their role in advancing animal health and productivity, aligning with the industry's goals of achieving sustainable and efficient livestock production.
