Ileal endogenous N losses (ENL) were measured, using the 15N isotope dilution technique, in piglets (17 kg) fed different barley genotypes (naked, spring, winter with low/high beta-glucan content) or diets containing 330, 530, 730 or 930 g of a blend of barleys/kg diet. The apparent protein and amino acid digestibilities of the naked variety and the winter variety with a high beta-glucan content were, on average, significantly higher than those for the other two varieties. The ENL were inversely correlated (p<0·01) with the apparent digestibilities but the difference between each of them was not significant (p>0·05). The ENL increased linearly with the inclusion level of barley in a N-free basal diet (2 mg endogenous N/g barley). Isolated hulls added to a N-free diet at the rate of 100 or 200 g/ kg diet exerted no significant effect on the ENL (1·80 g endogenous N/kg diet in both cases vs. 1·76 g for the basal level). On the contrary, the effect of isolated bran, measured under similar conditions, was significantly higher and dependent on fibre intake (2·59 and 3·31 g N/kg diet, respectively). It is concluded that the ENL are affected by the insoluble bran fibre but not by the hulls, nor by the level of beta-glucan. [less ▲]

The use of chestnut tannin (CT) (hydrolysable tannins), added at a low concentration (4 g CT/100 g of total nitrogen (TN) = 0,8 g cT/kg of DM distribute) to a grass forage for growing sheep, improves the N retention (P0,01). The improvement of N retention is explained by the decrease of nitrogen in the urine, indicating a better use of absorbed nitrogen. Moreover, the addition at these low concentrations of CT to fresh grass does not alter neither the digestibility of its constituents (OM, TN, ADF) nor the rate of ingestion. [less ▲]
