are inorganic components of the diet, commonly reported collectively on pet food labels as ash. Animals do not have an ash requirement but do have dietary requirements for individual minerals.
- Macrominerals are calcium, phosphorus, sodium, chloride, magnesium, and potassium. These are called “macro” because they are required in relatively large quantities (grams per day) compared to other minerals.
- Microminerals are iron, copper, iodine, zinc, manganese, and selenium. These are called “micro” because they are required in relatively small quantities (micrograms or less per day).
- There are minerals called “ultra-trace” such as chromium and boron; however, the minimum required by dogs or cats has not been determined. Based on the evidence in other species, chromium and boron should probably be included in their diet.
