| Popis: | Pigs were fed diets containing 40% wheat bran incubated with a water: acetic acid mixture (control, C) and a cellulase (Cel-i) or xylanase (Xyl-i) preparation or with addition of the cellulase (Cel-a) or xylanase (Xyl-a) preparation immediately before feeding. Stomach and ileal samples were analysed for pH, osmolality, soluble saccharides, volatile fatty acids (VFA) and lactic acid. Incubation of wheat bran resulted in a small reduction of NDF and an increase in the amount of soluble starch, B-glucans and saccharides (glucose, xylose and arabinose), especially after incubation with the cellulase preparation. Two hours after feeding, significantly higher arabinose and xylose concentrations were present in the stomach for diets Cel-i, Cel-a and Xyl-i. In the ileum xylose and arabinose concentrations were higher 2 to 4 and 6 to 8 hours after feeding the enzyme-treated diets. In stomach and ileum there were no differences between the diets in pH, osmolality, VFA and lactic acid concentrations, but ileal VFA concentration from 4 h after feeding tended to be higher for diets Cel-i and Xyl-i. It can be concluded that the amount of soluble saccharides in stomach and small intestine and the ileal VFA concentration may be increased by cell wall degrading enzyme preparations. |
