Pups of primiparous and multiparous Sprague Dawley rats received 0-, 2-, or 5-min cold stress on Days 2-6 postpartun. Stressed offspring of primiparous mothers had shorter latencies to move in an open field than did control offspring of primiparous mothers. However, stressed offspring of multiparous mothers had longer latencies than did the controls. The results suggest differences in maternal responsiveness immediately following return of stressed pups to the nest.
初产和经产斯普拉格-道利大鼠的幼崽在产后第2至6天接受0、2或5分钟的冷应激。初产母亲的应激后代在旷场中移动的潜伏期比初产母亲的对照后代短。然而，经产母亲的应激后代的潜伏期比对照后代长。结果表明，应激幼崽回到巢穴后，母体反应存在差异。
