Applications

Vitamin A is necessary for many functions in ruminants including: vision, bone growth, immunity and maintenance of epithelial tissue. Vitamin A is essential for proper vision and is utilized in the retina in the chemical reactions necessary for sight. Vitamin A deficiency results in night blindness and formation of ulcers on the cornea. Vitamin A affects bone development through its effect on bone metabolism. Essentially, Vitamin A deficiency results in unchecked bone growth that in turn manifests as malformed bones and joints. Vitamin A directly affects immunity through both production of antibodies and through maintaining an adequate barrier to infection with healthy epithelial cells. Vitamin A deficiency reduces the primary antibody response in the event of infection.
