Maternal separation and neonatal manipulation of pups produce changes in maternal behavior after the dam-pup reunion. Here, we examined whether continuous versus alternating days of neonatal manipulation during the first 8 postnatal days produces differential changes in maternal and non-maternal behaviors in rats. We found that both maternal separation protocols increased anogenital licking after dam-pup reunion, reflecting increased maternal care of pups.
