Calculate DM, Moisture, and DMI for any feed or animal
1. Convert As-Fed to DM Weight
If you have 100 kg at 35% DM:
2. Fresh Feed for Target DM
To get 20 kg DM at 35% DM:
3. Cost of Water (Waste)
If feed is $0.20/kg at 35% DM:
This feed contains 35% Dry Matter and 65% moisture. It is considered a moderately wet feed (silage).
For best quality, aim for 30–40% DM in silage.
| Feed Type | Typical DM % | Moisture % |
|---|---|---|
| Hay | 85–90 | 10–15 |
| Grass Silage | 30–40 | 60–70 |
| Maize Silage | 30–35 | 65–70 |
| Straw | 80–90 | 10–20 |
| Concentrate Grains | 85–90 | 10–15 |
Welcome to the ultimate AI Dry Matter Calculator at www.aianimalfeed.com. This advanced livestock feed analysis tool is designed to help farmers, nutritionists, and feed mill managers accurately convert as-fed weights to Dry Matter (DM) basis. In precision feeding, you cannot balance a ration without knowing the DM. This tool instantly calculates feed moisture content, ensuring accurate feed formulation for hay, silage, TMR, and concentrates.
Beyond simple moisture testing, this tool includes a Dry Matter Intake (DMI) calculator. Whether you are feeding dairy cattle, beef cattle, sheep, goats, or custom animals, understanding DMI is critical for predicting milk production and weight gain. If an animal fills up on water, it cannot consume enough nutrients.
Simply select a preset feed (like corn silage or alfalfa hay) or enter your own custom feed data. Our integrated AI nutritionist will analyze your sample and provide actionable recommendations for improving feed quality, preventing mold, and optimizing your feed cost per kg of DM.
"As-fed" refers to the feed exactly as it is given to the animal, including its natural water content. "Dry Matter" (DM) is the feed with all the water removed, representing only the solid nutrients. Because water content varies widely, nutritionists use DM to accurately compare feeds and balance rations.
You can use a microwave or oven. Weigh a fresh sample (e.g., 100g). Dry it thoroughly until it stops losing weight. Weigh the dry sample again. Use the formula: (Dry Weight / Fresh Weight) × 100. For example, if it weighs 35g dry, the DM is 35%.
Dry Matter Intake (DMI) is the amount of actual feed (excluding water) an animal consumes daily. It dictates milk production, weight gain, and overall health. If a cow cannot consume enough DMI, she will lose weight and drop milk production.
For optimal fermentation and feed quality, grass silage should be between 30% and 40% DM. Maize silage is usually slightly lower, around 30% to 35% DM. If it drops below 25%, you risk clostridial fermentation and nutrient runoff.
Feed is often sold by "as-fed" weight. If you buy 1,000 kg of silage at 30% DM, you are buying 700 kg of water. Calculating the cost per unit of Dry Matter allows you to compare different feeds fairly and avoid overpaying for high-moisture feeds.
The calculations provided by this tool are estimates based on the data you enter. For the most accurate feed analysis, always send samples to a certified agricultural laboratory. Always consult with a licensed veterinarian or animal nutritionist for precise ration balancing.
