About this calculator
Overview
Nutrition in animal feed or food products can be highly variable due to moisture content. Calculating dry matter (DM) allows for the comparison of nutrients between samples with different water levels.
💡
Pro Tips
Always weigh samples immediately after collection to prevent moisture loss from evaporation.
Dry samples (usually in an oven) until they reach a constant weight for maximum accuracy.
Nutrient concentration (e.g., protein %) always appears higher on a dry matter basis than as-fed.
Ensuring an 'apples-to-apples' comparison is critical for accurate ration formulation and quality control.

Fun Facts
"Corn silage is typically 30–35% dry matter, meaning it is more than two-thirds water."
"Fresh pasture can be as low as 15% dry matter during peak growing seasons."
"Grains and hay are usually around 85–90% dry matter to ensure shelf-stability and prevent mold."
