EFFECTS OF 3 MICROBIAL PROBIOTICS ON POSTPRANDIAL PORTO-ARTERIAL CONCENTRATION DIFFERENCES OF GLUCOSE, GALACTOSE AND AMINO-NITROGEN IN THE YOUNG-PIG

Postprandial kinetics of porto-arterial concentration differences of g lucose (G), galactose (Gal), L-lactic acid (LA) and amino-N (AN) were studied in the piglet after the ingestion of 10(7) colony-forming unit s (cfu) Sporolactobacillus P44 (SP), or 10(6) cfu Bacillus cereus IP58 32 (AC), or 10(6) cfu of a combination of Lactobacillus acidophilus, L . fermentum and L. brevis (AB)/g feed. Sixteen fistulated piglets (por tal vein and brachiocephalic trunk; mean body weight 22 (SD 2) kg) wer e used. The diet was based on skimmed milk (320 g/kg), barley (300 g/k g), 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 i ntervals, were studied for 6 h after the ingestion of test meals of 40 0 g basal diet (BD) or this diet supplemented with the bacteria (SP, A C and AB respectively). Areas of porto-arterial concentration differen ces (APACD) of G, Gal and LA were not influenced by the bacteria suppl ements. APACD of AN was significantly higher after the ingestion of th e SP diet than that estimated for BD.
