25.3 DRY MATTER

The amount of “dry matter” varies according to the food. For example, fresh, green forage contains about 70 percent water and 30 percent dry matter. Dried kernels of maize contain only 15 percent water and 85 percent dry matter. Even maize or corn flour that appears dry contains 10 percent water and 90 percent dry matter. Straw also contains about 10 percent water and 90 percent dry matter. 85% dry matter 30% dry matter Why is this important to know? The more dry matter in a food, the more an animal must drink. If an animal lacks water, it will lose its appetite and become malnourished, even if food is available. This is especially true when food is dry, like straw or cereal grains.

Some farmers do not give water to their animals, believing they get enough from forage. However, livestock must receive enough fresh water daily to be healthy and productive!
