Abstract：
:Effects of maternal separation on feeding behavior, particularly on rebound hyperphagia, in adult rats were examined. Time-restricted scheduled feeding (2 h per day for 6 days), was given at the age of 3, 6, 9 or 12 weeks in rats that were maternal separated from postnatal days (PD) 1-21 and control rats. Following the time-restricted scheduled feeding, rats were fed freely for 24 h (rebound hyperphagia). Body weight, daily normal food consumption and food consumption during time-restricted scheduled feeding and rebound hyperphagia were measured. Body weight of 3-week-old maternally separated rats were less than those of control rats. There was no significant difference in normal daily food consumption. Food consumption during rebound hyperphagia was significantly increased in 6- to 9-week-old female maternally separated rats, but there was no difference observed in males. Postnatal maternal separation enhanced rebound hyperphagia of female rats in later life. These results indicate that postnatal maternal separation made rats more vulnerable to the development of abnormal feeding behavior in response to food restriction in later life.
