- Abstract: Two hundred and forty mothers and their milk secretion were investigated in Hu-bei district. 130 of them were workers in the urban district and 110 peasants in the rural area of Tian-men County. Milk secretion, dietary intake and the composition of breast milk were examined. The overall mean energy intake of lactating mothers were over 2700 kcal/day both in urban and rural lactating mothers. The amounts of protein ingested were over 90g/ day in urban and more than 70g/day in rural women. The protein intakes in the first two months were significantly higher than in the remaining months. The animal and soybean protein in rural women were lower than in urban. Both the amounts of ingested fat and carbohydrate were suitable. The milk secretion of urban lactating mothers was higher than rural. The protein content of breast milk fall steeply from an initially high level during the first seven days and then more slowly up to at least the second month. The fat content was usually low during the first few days of lactation, but increased slowly to a level which was characteristic of the individual by the second month. The lactose content of urban was lower than rural. The body weights of babies in both urban and rural were nearly the same in the first three months. After forth month the growth rate of the rural infants was slower than the urban infants. So the weaning foods to provide to infants in the rural area was more urgent.
