Summary An estimation of the genetic and environmental correlations between prolificacy (kits born alive and number of kits at weaning) and functional longevity in a population selected for litter size at weaning since 1992 was carried out. The method is only an approximation, but suggests that genetically longevity and litter size are not antagonistic objectives in breeding programmes, because the estimated genetic correlations are not significantly different from zero.
