摘要
Four lactating cows fitted with permanent ruminal, duodenal and ileal cannulae were used to study the effect of extrusion of whole lupin seeds at 195-degrees-C (Lupinus albus cv Lublanc) on organic matter (OM) and nitrogen (N) degradation in the rumen and their flow to and absorption from the small intestine. Raw whole lupin seeds (RWLS) and extruded whole lupin seeds (EWLS) were fed in diets containing 15.5% crude protein and composed of 22.6% whole lupin seeds, 56.5% corn silage, 10.2% corn grain and 10.7% Italian ray-grass on a DM basis, supplemented with vitamins and minerals. Chromium ethylenediaminotetraacetic (Cr-EDTA) and ytterbium chloride (YbCl3) were used as liquid and particulate markers respectively, while purines and N-15 ammonium sulfate were utilized as bacterial markers. Cows fed EWLS had a similar ruminal ammonia N and volatile fatty acid concentrations and efficiency of bacterial protein synthesis compared to those fed the RWLS diet. Total tract OM and N digestion were not affected by inclusion of EWLS instead of RWLS; the corresponding mean values were 70 and 71%. Apparent degradation of OM and N in the rumen were 44 and 64% for diets containing RWLS, and 40 and 39% for EWLS diets. Feeding diets including EWLS both increased non ammonia N and dietary N flow to the duodenum compared with diets containing RWLS (472 vs 357 g/d) and (263 vs 153 g/d) respectively. Absorption from the small intestine (g/d and % entering) of dietary N was higher for EWLS diets (146 vs 62 g/d; 34 vs 15%). The PDIA, PDIE and PDIN contents (g/kg of DM) of RWLS were 18, 94 and 245 respectively; the corresponding values after extrusion were 145, 220 and 220.
