A previous study suggested that addition of fructo‐oligosaccharides ( FOS ) to the diet improved nitrogen (N) utilization and decreased acid detergent fiber ( ADF ) digestibility in guinea pigs. The present study was conducted to clarify the relationship between ADF digestibility and gastrointestinal mean retention time ( MRT ) in guinea pigs under FOS supplementation. Adult male guinea pigs were fed a commercial diet (50 g/day) with either 5% glucose (glucose group) or 5% FOS ( FOS group) for 12 days in individual metabolism cages. Unlike the glucose group, N utilization improved, but ADF digestibility significantly ( P < 0.05) decreased in the FOS group. MRT of solid digesta also significantly ( P < 0.05) decreased in the FOS group compared with that in the glucose group. We concluded that reduction of MRT of solid digesta containing FOS decreased ADF digestibility in guinea pigs.
