Horse facts as told by a Shetland pony.
Gypsy, the Equine Encyclopedia, tells why horses need VITAMIN A.
Vitamin A helps horses maintain good vision, especially at night. Horses need it for healthy skin and strong muscles. Lack of Vitamin A in equines can create problems such as a dull, scruffy coat, poor night vision (horses have much sharper night vision than people do) and severe anemia.
Toxic amounts of this vitamin can cause decreased blood clotting, poor skin quality and bone abnormalities.
Because microbes in the horse’s small intestine need beta-carotene to produce vitamin A, good sources include hay, grass and carrots.
