The experiments were conducted to determine volatile fatty acid, lactic acid and glucose contents in the sections of alimentary tract of pig. Furthermore, arterio-veneous differences of volatile fatty acid from sections of alimentary tract were determined. The animals had been fed either a alfalfa pellet supplemented or control diet before slaughter in 70 days. The results obtained were summerized as follows. 1) A high concentration and large quantity of volatile fatty acid characterized the colon of the pig. The concentration of volatile fatty acid in the caecum and colon of the pigs were nearly equal of that reported for the rumen of ruminants. 2) The lactic acid decreased progressively as the digesta passed along the alimentary tract. There was a tendency for the alfalfa fed pigs to have a less proportion of lactic acid in the digesta than the controls. The glucose was determined less quantity in the alimentary tract than organic acids. 3) A high arterio-veneous differences of volatile fatty acid were observed in the caecum and colonal vein. The absorption of volatile fatty acid were observed in stomach vein as well as caecum and colonal vein. The concentrations of volatile fatty acids in the portal vein were higher than the carotid artery in every experiments. The absorption of volatile fatty acid were observed in control and alfalfa fed pigs equaly. The concentration of volatile fatty acid in the portal vein of pigs were compared identically with those of ruminant animals.
