Chemical composition of cynomolgus monkey milk

Milk samples from eight cynomolgus monkeys whose lactation period ranged 44-119 days were investigated for their gross chemical composition such as total solids, crude protein, lipids, lactose and ash. Nitrogen distribution, compositions of fatty acids, amino acids and triglycerides as well as major minerals were also determined. These analytical data were compared with those reported for man, simian and cow, and cynomolgus monkey milk was found to have close similarities to human milk.
