The activity and distribution of proteinases and their inhibitors, lipases and amylases as well as the composition of the bacterial flora throughout small intestines of 20 slaughter pigs were investigated. It was demonstrated that the intestines were partly in contraction, partly in relaxation and that the contracted regions had no ingesta, only a scarce and mucous content. This type of content possessed no proteolytic activity while lipolytic and starch‐splitting activities as well as inhibitory substances against proteinase were always present. The contracted parts, which presented no regularity as to their length and localization, often appeared to be sterile. In the feed‐containing, relaxed regions of the intestines, the digestive enzymes examined were always present in high concentrations. Their activity was quite constant in all segments of the intestine. The proteolytic activity was partly based on trypsin. The main microorganisms found were Lactobacillus sps., α‐haemolytic streptococci and lactosepositive enterobacteria (coliform). The quantitative bacteriological findings varied considerably.
