Abstract:
... Resistant starch (RS) has caught much attention for its potential to exert a beneficial impact on intestine and certain members of its resident microbiota. In this study, we examined how dietary RS promotes intestinal barrier in meat ducks by microbiome-metabolomics analysis. Ducklings were fed corn-soybean basal diet or RS diet. Dietary RS improved intestinal morphology and enhanced barrier funct ...
