Which type of feed is most commonly used to provide energy in rations?

Grains are the most commonly used type of feed to provide energy in animal rations due to their high starch content and digestibility. Grains such as corn, barley, and wheat are often included in feed formulations because they are sources of carbohydrates, which are the primary energy source for many livestock and poultry species. The energy derived from grains supports growth, reproduction, and overall maintenance of body functions.

While mineral-rich feeds provide essential vitamins and minerals necessary for health, and protein concentrates supply necessary amino acids, their primary functions are not energy provision. Similarly, fiber-rich feeds are important for digestive health and can contribute to energy, but they do not offer energy in the same quantifiable and straightforward manner as grains do. Therefore, in the formulation of balanced animal rations, grains are favorably included as the primary energy source.
