We studied the effects of polydextrose (PD) onfecal weight andgastrointestinal transit time by the Latinsquaremethod in a cross-over fasionusing 9 male beagle dogs. Animals weredivided to 3 groups: control group (PD free) , PD 2.5% group and PD5.0% group and fed with each diet for 11 days with the wash outperiod of 7 days . Body weight gain, food intake and waterintakewere not affected by polydextrose ingestion. The fecal weightwas increased significantly in PD 5.0% group in compared with thatof the control group. Also, the hardness of feces was softer in thegroups fed PD than in the control group. However, thegastrointestinal transit time was not affected significantly by PDingestion. These results suggest that PD is one of the dietaryfibers which improve on defecation and fecal status.
