Human milk from different periods of lactation was analysed. The following constituents of 100 g human milk decrease from the 1st week to the 2nd-3rd month of lactation: protein from 1.57 to 0.81 g, ash from 0.36 to 0.21 g, sodium from 54.4 to 13.1 mg, potassium from 63.6 to 48.1 mg, chloride from 109.8 to 39.1 mg and sulfur from 28.0 to 11.9 mg. There are no significant changes during lactation for calcium with 28.8-25.6 mg and for magnesium with 3.3 mg. The concentration of phosphorus increases during the first week of lactation from 8 to 12 mg/100 g and remains at this level. Zinc decreases from 642 to 166 micrograms milk during lactation. The concentration of manganese is between 1.1 to 1.8 micrograms. The almost similar concentration of iron and copper increases during the first 14 days of lactation from 48.4 to 62.2 micrograms and 45.8 to 66.9 micrograms respectively, and then decreases to 26.0 and 30.7 micrograms respectively in the 2nd-3rd month of lactation. During the period of lactation there is an increase for lactose from 4.9 to 6.1 g and for total-thiamin from 10.1 to 284 micrograms/100 ml.
对不同哺乳期阶段的母乳进行了分析。100克母乳中的以下成分从哺乳期第1周降至第2 - 3个月：蛋白质从1.57克降至0.81克，灰分从0.36克降至0.21克，钠从54.4毫克降至13.1毫克，钾从63.6毫克降至48.1毫克，氯从109.8毫克降至39.1毫克，硫从28.0毫克降至11.9毫克。哺乳期内钙（28.8 - 25.6毫克）和镁（3.3毫克）无显著变化。磷的浓度在哺乳期第一周从8毫克/100克增加到12毫克/100克，并保持在这一水平。哺乳期内锌从642微克/100克母乳降至166微克/100克母乳。锰的浓度在1.1至1.8微克之间。铁和铜的浓度在哺乳期前14天分别从48.4微克增加到62.2微克和从45.8微克增加到66.9微克，然后在哺乳期第2 - 3个月分别降至26.0微克和30.7微克。哺乳期内乳糖从4.9克增加到6.1克，总硫胺素从10.1微克/100毫升增加到284微克/100毫升。
