Vitamin D is normally produced following skin exposure to ultraviolet-B. Since most piglets (and humans too!) are raised in climate controlled housing and born year-round, direct access to sunshine is often limited, even in the summer. Fortunately, vitamin D can be added to diets to meet the animals' need for vitamin D.
