A complete feed is defined by its ability to provide all the necessary nutrients required for a specific animal's diet in sufficient quantities. This means that a complete feed contains the right balance of carbohydrates, proteins, fats, vitamins, and minerals necessary for the animal's health and well-being. It is formulated to be the sole source of nutrition so that no additional feed is needed for the animal to meet its dietary needs.

On the other hand, a supplement is intended to enhance the diet but does not provide a full nutritional profile on its own. Supplements are usually added to the diets of animals feeding on a base diet that may be lacking in specific nutrients, often focusing on vitamins, minerals, or other nutrients that may be deficient. Therefore, the fundamental distinction between the two lies in the completeness of the nutrition they offer, with complete feeds serving as a standalone source of all nutrients, while supplements serve to enhance or improve the nutrition provided by other feeds.
