Lactation patterns in Egyptian women I. Milk yield during the first year of lactation

The milk yield in a group of lactating Egyptian women was estimated during the first twelve post-partum months. It increased from the second to the seventh month, then dropped gradually in the last four months. The best milk yield was found in women aged 20–30 years, with a parity of two to four and an inter-delivery interval of 30–36 months. (Summary in Arabic, p. 401.)
