PLEASE NOTE: Other components are not provided here (e.g. amino acids, fatty acids, iron, iodine, copper, selenium, and many other elements); this does not imply they are of lesser significance. THE PROBLEM: WE DO NOT KNOW THE DIETARY COMPONENT REQUIREMENTS OF THE OPOSSUM. NOR HOW THOSE REQUIREMENTS CHANGE WITH AGE OR OTHER CONDITIONS.

a. Unavailable data.

b. In National Opossum Society diet, its use constitutes no more than 10% of total day's ration in adult (i.e., approximately 10 grams), down to less than 2% (i.e. approximately 2 grams) in a l-pound opossum (juvenile).

c. Calcium:Phosphorus ratio approximately 1.1:1.0 with bone.

d. Vitamin A of plant origin not as readily available as that from animals; thus, useful amount is less than indicated.

e. Actual quantity egg yolk per cup of formula is approximately 8 ml. (8 grams), or approximately of a 17-gram yolk.

f. NOT RECOMMENDED BY NATIONAL OPOSSUM SOCIETY FOR USE IN OPOSSUMS AT ANY TIME.
