We evaluated in pups of Akodon azarae both growth pattern from birth to 48 days of age and the effect of litter size on growth pattern and homeothermy acquisition from birth to weaning age. Individual pups gained weight as expected by a Gompertz growth pattern. Until weaning, litter size affected both the slope of the relationship between body temperature and age and the rate of growth of pups. Pups from small litters increase both body temperature and weight until body temperature and weight of adults at higher rates than those from large litters.
