Abstract
ABSTRACTRats were fed a semi‐purified diet containing 63% puffed wheat (PW) or 63% shredded wheat (SW) breakfast cereals for 6 wk. A 16% unprocessed wheat bran (WB) diet was used as control. The neutral detergent fiber (NDF) content was 3.2%, 1.9%, and 1.9% in diets PW, SW, and WB, respectively. Feces were collected during three 96‐hr periods: fecal weight and volume were lower (P < 0.001), fecal density was higher (P < 0.001), and intestinal transit time was longer (P < 0.01) in group PW than in groups SW and WB. Results indicate that the dietary fiber content of puffed wheat breakfast cereals is lower than that of shredded wheat breakfast cereals.
