Salt Salt is lost through sweating and urine, and the requirements are, therefore, influenced by activity level and weather. Salt is most efficiently supplied on a free choice basis, the individual pony will adjust its intake according to its need. Salt toxicity can occur if a salt deprived animal is suddenly allowed access to salt, or if salt is added to the feed while water is restricted. Vitamins Vitamins are compounds that are required in very small amounts but are essential for normal metabolism. Vitamin supplements are rarely indicated if a well balanced diet is provided.
Some exceptions do exist.
Green pasture is high in vitamin A, but much is lost during drying and storing. It is possible for a pony to become vitamin A deficient if he is fed hay low in vitamin A for longer than 6 months. Both vitamins A and D are stored in the body for several months, so these vitamins should only be supplemented if there is a definite concern of deficiency. This factsheet is one a series written, in conjunction with the Newfoundland Pony Society , on the care of Newfoundland Ponies.
