Milk samples were collected from 35 mothers delivering preterm infants and from 35 mothers delivering term infants at 3 time intervals over the first 3 weeks of lactation. The samples were collected by manual expression from both breasts into polyethylene containers and were frozen at -20 degrees C and stored for analysis. The protein content of preterm milks during the first and second weeks is higher than that of term milk (P less than 0.05). The fat and lactose contents during the first week are slightly more in term milk than in preterm milk. During the third week the fat content of preterm milk is higher but its lactose content was lower. All these differences are not significant. These results are discussed.
在哺乳期的前三周内，分三个时间间隔从35名早产产妇和35名足月产产妇中采集了乳汁样本。样本通过手工挤奶从双侧乳房收集到聚乙烯容器中，然后在-20摄氏度下冷冻保存以备分析。早产乳汁在第一周和第二周的蛋白质含量高于足月产乳汁（P<0.05）。足月产乳汁在第一周的脂肪和乳糖含量略高于早产乳汁。在第三周，早产乳汁的脂肪含量较高但其乳糖含量较低。所有这些差异均无统计学意义。对这些结果进行了讨论。
