[The bacterial fraction in swine feces].
By a treatment with a solution of detergent, subsequent sedimentation and centrifugation faeces samples taken from 12 growing female pigs were divided into: fraction A (coarse particles), fraction B (finer particles), fraction C (bacteria fraction). N-, AA- and diamino pimelic acid (DAP) analyses as well as microscopic analyses were carried out with the complete samples and the fractions. By means of fractioning, 55% of the faecal N and 80% of the DAP could be concentrated in fraction C, fraction A contained approximately 23% of the N and 20% of the DAP. From the DAP: N quotient of fraction C, which was 65 mg DAP/g N, a quota of nearly 70% bacteria-N in the total faecal N of the pigs was calculated.
