The effects of dietary wheat bran on bile flow, content of total bile acids and cholesterol, and bile acid pool size were studied in growing male pigs. The pigs were divided into 2 groups, one group receiving a 40% wheat bran diet and the other group receiving a diet containing no bran. The diets were isoproteic and isocaloric. For a period of 5 d, steady-state bile flow rate was continuously sampled for cholesterol and bile acid analyses. Following the 5-d period, bile acid pools were determined. There was a marked difference between the two groups of pigs in the daily fluctuation pattern of bile flow, and the total daily volume of secreted bile as well as the total daily cholesterol output were significantly greater (p<0.001) for the pigs consuming the 40% bran diet. Also, the daily bile acid concentration was lower (p<0.05) in the bran-fed pigs.
