A total twelve pairs NBW piglets (7 d old) were randomly assigned to two different nutrient-level formula milk...

Soluble dietary fibers (SDF) are fermented more than insoluble (IDF), but their effect on colonic bacterial community structure and function remains unclear. Thus, composition in the colon of BALB/c mice (n = 7) fed with a high level (approximately 20%) typical SDF, oat-derived β-glucan (G), microcrystalline cellulose (M) as IDF, or mixture (GM), were compared. Mice group G showed lowest average feed intake (p < 0.05) no change body weight gain > compared to other groups, which may be...
