在出生前一天，大鼠胎仔对口内输注乳汁的反应是牵拉反应，类似于哺乳幼崽在乳头处的行为。不像出生后的反应，这发生在同时与乳汁排出，胎儿拉伸发生后3-5分钟输注乳汁。测量胎儿心率（HR）可作为胎儿牵张反应的预测指标。拉伸反应的表达之前，在HR变异性和心动过缓的短暂发作减少。未伸展的胎仔显示HR变异性延迟降低，且无HR减速证据。胎儿心率的系统性变化可能表明与输奶和牵拉反应相关的胎儿状态变化。
On the day before birth, rat fetuses respond to an intraoral infusion of milk with a stretch response that resembles the behavior of suckling pups at the nipple. Unlike the postnatal response, which occurs coincident with milk ejection, the fetal stretch occurs 3–5 min after milk infusion. Measurement of fetal heart rate (HR) is useful as a predictor of the fetal stretch response. Expression of the stretch response was preceded by a reduction in HR variability and a transient episode of bradycardia. Fetuses that did not stretch showed a delayed reduction in HR variability and no evidence of HR deceleration. Systematic changes in fetal HR may be indicative of changes in fetal state associated with milk infusion and the stretch response.
