    Abstract

    1. 1. Twenty one sequential milk samples from an American marsupial (Monodelphis domestica) were analyzed. 2. 2. The solids fraction was relatively low initially (10% w/w) and then increased to about 30% at mid-lactation where it remained until lactation ceased. 3. 3. During the first 50 days of lactation the relative proportions of protein, fat and carbohydrate were 36, 28 and 34%, respectively, of the solids fraction. 4. 4. Sodium and magnesium concentrations were constant; however levels of potassium and magnesium varied substantially. 5. 5. The milk of M. domestica exhibits a similar pattern of quantitative and qualitative changes to that seen in Australian marsupials.
