Ash: farm glossary
Ash is the total inorganic mineral residue left after a feed sample is burned in a laboratory. It is commonly expressed as a percentage of the sample or dry matter. Ash describes that residue as a whole. Individual minerals, including calcium and phosphorus, have separate values in the feed’s composition.

A farm example
Illustrative calculation: a forage analysis showing 9% ash on a dry-matter basis means 90 g of every 1 kg of forage dry matter is total inorganic residue—including nutritional minerals like calcium and phosphorus as well as any soil or sand contamination.
Everyday use
HerdMobile feed profiles show ash and individual nutrient values where available. Ash describes the overall mineral residue, while the daily ration uses the selected feeds’ individual nutrients and amounts.
