✦ Synopsis

One week prior to mating, female rats were adrenalectomized or sham-operated and, immediately following parturition, each was given a foster litter of 10 newborn pups from a mother in the same group. Retrieving measures at the time of fostering revealed no significant differences between the 2 groups. Over 16 days of maternal behavior observations the adrenalectomized mothers spent more time in the nest, more time in an active suckling position, and tended to keep the pups in the nest over a longer period of time. These results provide evidence that a functioning adrenal is not necessary for the initiation or maintenance of maternal responsiveness in rats. adrenalectomy maternal behavior laboratory rat
