对11名足月母乳喂养婴儿出生后120小时内的乳汁摄入量和特定营养素的摄入量进行了测量。婴儿在所有饲料中使用电子秤进行称重，并每天从双乳中采集乳汁样本一到三次。分析了牛奶中脂肪、蛋白质、乳糖、钙、钠和钾的含量；能量含量使用阿特沃特系数计算。平均(.+-.SD)出生后24小时内的牛奶摄入量为13。+-。16 g/kg(范围3到32 g/kg)增加到98.+-。47克/公斤(50至163克/公斤)和155。+-。29g/kg(110~196g/kg)，分别于第3、5天灌胃。能量、乳糖、钙和钾的平均日摄入量在出生后第1天不到第5天平均摄入量的12%，在第2天不到第5天摄入量的25%。在出生后的头几天，纯母乳喂养婴儿的营养摄入量变化很大，而且往往很低。
The intakes of milk and specific nutrients during the first 120 hours after birth were measured in 11 full-term, breast-fed infants. Infants were test weighed at all feeds using an electronic balance, and milk samples were obtained from both breasts one to three times daily. Milk was analyzed for levels of fat, protein, lactose, calcium, sodium, and potassium; energy content was calculated using the Atwater factors. The average (.+-. SD) intake of milk in the first 24 hours after birth was 13 .+-. 16 g/kg (range 3 to 32 g/kg) increasing to 98 .+-. 47 g/kg (50 to 163 g/kg) and 155 .+-. 29 g/kg (110 to 196 g/kg) on days 3 and 5, respectively. Mean daily intakes of energy, lactose, calcium, and potassium were less than 12% of the mean day 5 intake on day 1 and less than 25% of the day 5 intake on day 2. In the first few days after birth, the nutrient intake of the solely breast-fed infant is highly variable and is frequently low.
