The compositions were determined for a grevyi zebra's milk, bred at Kyoto city zoo, at around 1, 2, 3, 4, 5 and 8 month post partum. The change of the concentrations of lipid, protein, carbohydrate and ash was small during the lactation, and calculated as 1.9±0.55% (average±standard deviation), 1.7±0.22%, 6.3±0.57%, and 0.3±0.06%, respectively. The concentration of protein decreased during the course of lactation, and that of carbohydrate decreased until 5 month, while that of lipid decreased from 2 to 5 month post partum. The concentrations of lipid and protein were smaller than those in bovine milk, while that of carbohydrate was higher than that in bovine milk. The composition was similar to those of horse and donkey, which are closely related animal species.
