Abstract
Reproductive performance of a laboratory colony of old-field mice was compared with wild old-field mice of the AEC Savannah River Plant, Aiken, South Carolina. Fertility of males and females declined about 10% in the 1st generation born and raised in the laboratory as compared to the wild-trapped mice which formed the basis of the colony. Incidence of pregnancy, size of litter, survival of young increased with domestication. Litter size was statistically significantly larger in lactating compared with nonlactating mice and in the 1st-generation lactating females compared with wild- trapped lactating females.This publication has 0 references indexed in Scilit:
