title: [2,6-Diaminopimelic acid (DPA) content and the DPA:N ratio in rumen bacteria in relation to time after feeding].
abstract: The interrelation between the time of the withdrawal of rumen fluid and the DPA: N-relation in the fraction of mixed rumen bacteria was ascertained in a test with two cows with rumen fistulae. At the moment of feeding the DPA-content of 63 mg per g bacteria was very high. In the period of 3 to 9 hours after feeding it remained relatively constant (50 mg). A mean conversion relation of 20.4 of DPA to bacteria N was ascertained. The amino acid model proved to be the same in all fractions, the content values were comparable to those found in technical literature.
