Vitamins are a unique dietary component for beef cattle and are categorized into two groups: water-soluble and fat-soluble. Bacteria in the rumen synthesize water-soluble vitamins (e.g. B12, thiamin, niacin). Therefore, supplementation is generally not needed as long as the rumen if functioning properly. This leaves the fat-soluble vitamins (A, D, E, and K). Of these, Vitamin A is considered the most important when feeding cattle.

Vitamin A, also known as retinol, is a compound that is essential for growth, reproduction, maintenance of body tissue, and bone development. Technically, Vitamin A is not .
