What does "dry matter" calculation signify in animal feed?

The concept of "dry matter" in animal feed refers to the total weight of food after all the moisture has been removed. This calculation is crucial in nutrition because it allows for a consistent comparison of the nutrient content across different types of feeds. Different feeds can contain varying levels of moisture, leading to potential misinterpretations of their nutrient density when assessed solely by their total weight.

By focusing on the dry matter, one can accurately determine the amount of nutrients available for absorption by the animal. Understanding this number helps in formulating diets that meet the specific nutritional requirements of the animal, ensuring they receive the best possible care and nutrition. This approach is particularly important when comparing the nutrient profiles of different feedstuffs, as it standardizes the measure regardless of moisture content.
