Resumen:
To assess the use of conspecific odors to commensal M. musculus control, we studied the effect of overcrowding on the reproductive success of females in laboratory conditions. While pregnancy rates, litter size, the weight at birth and survival until weaning did not differ between overcrowding and control groups, the time elapsed until pregnancy, the mean weight and the total number of offspring surviving at weaning were higher in the control group. Control females produced a mean of 1.25 offspring, while overcrowded females produced 0.6. A lower weight of the offspring of crowded females may affect their future chances of survival and reproduction.
