Everyday vitamins and minerals.
The domesticated horse is often deprived of the correct amount of nutrients as we remove them from their natural habitat. Your horse requires several minerals to meet a variety of functional needs; these are macro minerals (those needed in relatively high amounts) There are also minerals called trace minerals (those needed in relatively small amounts) Horse feeds tend to be variable in many minerals, and as they are usually low in sodium and chloride (salt), it is recommended that you offer your horse some kind of salt source, such as a salt block.
Vitamins are classified as water-soluble or fat-soluble. Fat-soluble vitamins, include A, D, E, and K, while the water-soluble vitamins include the B complex and vitamin C. Horses, unlike humans can create their own vitamin C and therefore generally do not require it in their diet. Vitamin D is found in good amounts in sun-cured forages and sunlight. Vitamins A and E are found in variable amounts in pasture and hay, with higher amounts found in pasture during the spring months and in hay that hasn’t been stored for too long.
Often at this time of year horses can appear a little ‘flat’ or perhaps their coat is lacking its usual shine, goodness has gone from the hay and there is no grass available with any nutritional content. If this is the case then a vitamin and mineral supplement may be beneficial. There are many different types of vitamin and mineral supplements available, choose a well know brand for quality assurance and follow the feeding advice on the packaging.
