From wheat bran to equine gut: the in vitro fermentation dynamics of aleurone

The findings suggest that aleurone's structural matrix may influence metabolite release and microbial access, highlighting its functional role in modulating fermentation and overall host metabolism. In this study, we demonstrate that aleurone alters microbial fermentation and metabolite output in a time- and compartment-specific manner. These insights enhance our understanding of aleurone as a functional feed component in horses and provide a foundation for future dietary strategies targeting metabolic and gut health.
