Feeding and breeding of laboratory animals: XIV. Size of Breeding Group and Production in Mice

Abstract

1. The production of weaned young from pairs or groups of three, four and five mice, each containing one male, has been compared.2. For long-term large-scale production, small breeding groups of one male with two females are proposed.I should like to thank Dr A. S. Parkes, F.R.S., for much helpful criticism, and Dr Walter Perry for the statistical tests.
