A longitudinal study of rhesus monkey (Macaca mulatta) milk composition: Trace elements, minerals, protein, carbohydrate, and fat

Abstract

The concentrations of iron, copper, zinc, calcium, magnesium, sodium, potassium, protein, carbohydrate, and fat were analyzed in milk from rhesus monkeys (Macaca mulatta) during the course of lactation. Concentrations of iron, copper, zinc, magnesium, sodium, potassium, and protein were higher in milk of early lactation (colostrum) than in mature milk, while concentrations of calcium increased with lactation time. Concentrations of zinc in monkey colostrum and mature milk were similar to that of human milk, while iron, copper, calcium, and protein concentrations were higher than in human milk. © 1984 International Pediatric Research Foundation, Inc.
