Intensive Breeding of Mice

Abstract

Summary1. Production figures are given for a small mouse colony.2. High productivity depends upon careful selection of breeding stock.3. This selection has been based on an analysis of individual records. Both the keeping and the analysis of records are easy and simple.4. In addition to providing a basis for selection, these records make possible a forecast of future production.I particularly wish to thank Miss D. Lawrence, the animal technician whose skill in looking after this colony has contributed so much to its successful performance.
