Abstract:

Calculation was made in respect of 10 confined populations of white mice that production of newborn mice is about 19.4%, production due to reproduction, i. e. production of young during the time when they are fed solely by their mothers - 39.0% of total production of the population. The error consisting in including newborn mice twice in production (as newborn young and as embryos) is about 3.9% of total production.
