Meaning of Ash Content

Ash content refers to the total mineral content remaining after food is completely burned during laboratory analysis. Despite the name, ash itself is not added to pet food. 

The measurement reflects naturally occurring minerals such as calcium, phosphorus, magnesium, and potassium within the ingredients. Bone-heavy foods and mineral-rich ingredients generally produce higher ash values. 

In raw feeding discussions, ash content is often referenced when evaluating bone inclusion and overall mineral balance. The number provides insight into the food’s mineral composition rather than ingredient quality alone.
