4 added 2/21/02; “Our published energy value of 5.6kJ/ml or 1.3Cal/ml is metabolisable energy. This is equivalent to gross energy of 6.1kJ/ml or 1.5Cal/ml.
Using the standard values of 25kJ/g for protein, 37kJ/g for fat and17kJ/g for carbohydrate produces a gross energy value for Opossum milk of 8.5kJ/ml or 2.0Cal/ml. As you are feeding the animals ad lib they will drink sufficient milk each day to satisfy their energy requirements. Since both the Wombaroo and Opossum milk have similar protein to energy values, 13.4mg/kJ for Wombaroo and 12.9mg/kJ for Opossum milk, then daily protein requirements will also be satisfied.”
