Distribution of rumen ciliates, bacteria and their products in the various parts of the gut of cattle was investigated. The concentration of volatile fatty acids was high in the rumen and caecum and that of lactic acid high in the jejunum and ileum, Gram-negative bacteria, such as Bacteroides, Veillonella and Selenomonas, were mainly isolated from the rumen and caecum, and Gram-positive bacteria, such as Streptococcus and Lactobacillus, from the jejunum and ileum. No difference was recognized between the numbers of the rumen ciliates in the rumen and reticulum. However, the number in the omasum was about 13. 4% of that in the rumen. About 69% of the survival ratio of the ciliates was recognized in the omasum. It was assumed that the ciliates in the rumen and reticulum had made their escape from the outflow toward the omasum for certain reasons. Very few ciliates were detected from the parts of the gut lower than the abomasum. However, the ciliates appearing in complete form were hardly observed in these parts. From the results, it seemed that the degree of designation of such region as nitrogen sources should be decreased more than formerly thought.
