title: [On the biological characterization of the outbred strain of Chbb : NMRI (SPF) mice / 1st comm.: Characterization of breeding stock under constant conditions of nutrition (Part II) (author's transl)].
abstract: The second part continued the biological characteization of the outbred strain Chbb : NMRI (SPF) (formerly NMRI/Tübingen/Kisslegg/Biberach) mice. The results obtained from 7 generations (F9 to F 15-generations) refer to the following parameters: loss of breeding animals, conception rate, ability to build a nest, litter size at birth and weaning, loss of young animals, litter weight at birth and weaning, intervals between two births and efficienty quota.
