Abstract: | Developmental parameters of mother-infant interactions in Acomys cahirinus were investigated in a series of observational and experimental studies. The uniquely precocial offspring associated closely with both parents beyond the time of weaning and birth of the next litter. The survival rate of foster pups was dependent upon both the age of the pups and the physiological stare of the foster mothers. While 1 and 8-day post partum ♂♂ nursed unfamiliar neonates as frequently as their own pups, they interacted with unfamiliar 8-day-old offspring less than with their own. |
