- Abstract
- On a dry matter (DM) basis, the date pulp (DP) used in our experiments was composed of 10% crude protein (CP), 2% fat and 63% total dietary fibre (TDF). The latter included 53% lignocellulose (acid detergent fibre, ADF), 38% lignin (acid detergent lignin, ADL) and 15% crude fibre (CF). The DP was considered as a source of water-insoluble fibre. Twelve male Wistar rats (3 months old, 312 g mean liveweight) were used. A semi-synthetic control diet containing 2% cellulose and a 20% dried DP diet containing 15% TDF including 5% CF, were compared. Daily feed intake was 14 g. By comparison with the control diet, the apparent digestibility of the DP diet was lower with respect to the DM (79 vs. 92%), the organic matter (OM) (82 vs. 95%) and the CP (68 vs. 85%), but was higher with respect to the CF (26 vs. 11%). The faecal bulk for the animals on the control and DP diets was 1.5 and 4.3 g day-1, respectively. Mean retention time of chromium was increased from 20 to 40 h by the DP intake. All the differences were highly significant (P < 0.001).
