Postprandial kinetics of porto-arterial concentration differences of glucose (G), galactose (Gal), L-lactic acid (LA) and amino-N (AN) were studied in the piglet after the ingestion of 10(7) colony-forming units (cfu) Sporolactobacillus P44 (SP), or 10(6) cfu Bacillus cereus IP5832 (AC), or 10(6) cfu of a combination of Lactobacillus acidophilus, L. fermentum and L. brevis (AB)/g feed. Sixteen fistulated piglets (portal vein and brachiocephalic trunk; mean body weight 22 (SD 2) kg) were used. The diet was based on skimmed milk (320 g/kg), barley (300 g/kg), wheat bran (110 g/kg), maize (100 g/kg) and lactose (70 g/kg). The postprandial blood kinetics, four measurements per animal at 1-week intervals, were studied for 6 h after the ingestion of test meals of 400 g basal diet (BD) or this diet supplemented with the bacteria (SP, AC and AB respectively). Areas of porto-arterial concentration differences (APACD) of G, Gal and LA were not influenced by the bacteria supplements. APACD of AN was significantly higher after the ingestion of the SP diet than that estimated for BD.
在仔猪摄入每克饲料含10⁷菌落形成单位（cfu）的芽孢乳杆菌P44（SP）、或10⁶ cfu蜡样芽孢杆菌IP5832（AC）、或10⁶ cfu嗜酸乳杆菌、发酵乳杆菌和短乳杆菌组合（AB）后，研究了葡萄糖（G）、半乳糖（Gal）、L-乳酸（LA）和氨基氮（AN）的餐后门静脉-动脉血浓度差的动力学变化。使用了16头安装了瘘管的仔猪（门静脉和头臂干；平均体重22（标准差2）千克）。日粮以脱脂牛奶（320克/千克）、大麦（300克/千克）、麦麸（110克/千克）、玉米（100克/千克）和乳糖（70克/千克）为基础。在摄入400克基础日粮（BD）或添加了细菌（分别为SP、AC和AB）的该日粮的试验餐后6小时，研究了餐后血液动力学，每只动物每隔1周进行4次测量。G、Gal和LA的门静脉-动脉血浓度差面积（APACD）不受细菌添加的影响。摄入SP日粮后，AN的APACD显著高于BD估计值。
