Pantothenic acid, folic acid, and vitamin B12 have very specific roles in the metabolic processes within the body. Each of these vitamins has a unique role in the formation of compounds essential for life. The concentration and availability of these vitamins in feedstuffs is highly variable. Folic acid is normally present in amounts adequate to meet the needs of growing animals. Supplemental folic acid may be needed for reproducing animals. Pantothenic acid and vitamin B12 are normally supplemented in monogastric diets. Ruminant animals can produce the B vitamins they need in the rumen under most production practices. Additional research on the role of B vitamins in metabolism is ongoing.
