title: [Species-specific odor in closely related species: period of development in ontogenesis of house (Mus musculus musculus) and mound-building (Mus spicilegus) mice].
abstract: In two-choice odor tests, it was shown that house and mound-building mice began to discriminate the species-specific odor of young at the age of 17 days. The mice investigated the odor of conspecific urine significantly longer than that of heterospecific urine, when the young donors of urine, were 17 days old or older. Thus, the species-specific odor appears in ontogenesis of these species on the 17th day of life.
