Role of Activity of Gastrointestinal Microflora in Absorption of Calcium and Magnesium in Rats Fed [beta]1-4 Linked Galactooligosaccharides

Role of Activity of Gastrointestinal Microflora in Absorption of Calcium and Magnesium in Rats Fed [beta]1-4 Linked Galactooligosaccharides

Rats fed a diet containing β1-4 linked galactooligosaccharides (GOS) (5 g/100 g of diet) absorbed calcium and magnesium more efficiently than those fed the control diet. However, the increment obtained through GOS-feeding was reduced by neomycin sulfate 0.67 g/100 g of diet). Since the decrease in c...

description Rats fed a diet containing β1-4 linked galactooligosaccharides (GOS) (5 g/100 g of diet) absorbed calcium and magnesium more efficiently than those fed the control diet. However, the increment obtained through GOS-feeding was reduced by neomycin sulfate 0.67 g/100 g of diet). Since the decrease in cecal pH in rats fed GOS was suppressed by neomycin-feeding, bacterial action in the digestive tract was considered to be reduced by neomycin-feeding. Our findings suggest that the action of intestinal bacteria is necessary for the effects of GOS.
