In proximate feed analysis, which component represents mineral content?

• A. Moisture
• B. Crude Protein
• C. Ether Extract
• D. Ash

Answer: (D)

In proximate feed analysis, the mineral content is represented by the ash fraction. After removing moisture and burning off all organic matter, the remaining residue is inorganic minerals, collectively called ash. This makes ash the best indicator of total mineral content, since it reflects the inorganic residue left behind, including elements like calcium, phosphorus, potassium, and others. The other components measure different things: moisture is water content, crude protein reflects nitrogen-containing compounds, and ether extract measures fats. So ash uniquely corresponds to minerals in proximate analysis.
