In proximate analysis, ether extract measures what component?

Explanation:
Ether extract measures the crude fat in a feed. In proximate analysis, a dried sample is extracted with a non-polar solvent like diethyl ether, which dissolves fats and other ether-soluble substances. The amount that is dissolved and recovered as the ether extract represents crude fat, a key energy-yielding component. Moisture is determined by drying, minerals by ashing, and crude fiber by acid/alkali digestion, with the remaining portion (not including fat, water, minerals, or fiber) estimated as nitrogen-free extract.
