For all the eye they obtain, carbohydrates, proteins and fat might appear to be a very powerful elements in your horse’s food regimen. But nutritional vitamins and minerals additionally play an important position in all kinds of his physique processes. These natural compounds are available from recent and dried forage and, to a lesser extent, grains. As a end result, most pleasure horses can meet their each day vitamin wants by consuming good high quality grass or hay.
On the opposite hand, broodmares, kids, elite equine athletes and horses recovering from sickness or experiencing stress usually require extra nutritional vitamins than even the very best hay can present. For these horses, a business feed formulated for the suitable stage of life or exercise stage will usually present the wanted further nutritional vitamins, every within the applicable quantity. Another choice is a focused supplementation—including a selected vitamin formulation to the each day ration to reduce the danger of inducing a probably dangerous imbalance or extra.

To make it easier to higher fulfill your horse’s dietary wants, we’ve ready this concise information to most important nutritional vitamins and minerals in his food regimen.
1. Vitamin A
Function: chief element of the light-sensitive pigment within the rods of the retina, making it essential to imaginative and prescient, notably at evening. Vitamin A additionally facilitates cell differentiation and regeneration, taking part in a essential position in development and therapeutic.
Source: produced within the physique from carotene pigments acquired from inexperienced forage and saved in fats cells; extra is stored within the liver for future use.
Imbalance dangers: deficiency is uncommon in mature horses fed ample forage. Foals poor at delivery could also be weak, gradual to develop and/or develop evening blindness. Excess happens solely by way of over supplementation; pasture and hay can not provide the poisonous stage. Dull coat, fragile bones, poor liver and kidney perform might all happen with toxicity.
2. Vitamin B1 (thiamin)
Function: helps metabolize carbohydrates and extract power from the food regimen.
Source: produced by gastrointestinal micro organism microflora however in an quantity inadequate to fulfill horses’ wants. Fresh and dried inexperienced leaves and cereal grains with husks provide the stability.
Imbalance dangers: deficiency is unlikely in horses who obtain high-quality forage. However, intestinal illness or parasites can intrude with the vitamin’s synthesis within the intestine. Some poisonous crops, akin to bracken fern, also can inhibit absorption. Signs of deficiency embrace lethargy, lack of urge for food and nervous-ness. Excess is sort of all the time resulting from injections given to spice up efficiency horses and indicators embrace excitability, labored respiration and convulsions.
3. Vitamin C (ascorbic acid)
Function: facilitates the synthesis of collagen, the first element of connective tissue
Source: manufactured within the horse’s liver. Ingested Vitamin C is damaged down by gastroin-testinal micro organism earlier than reaching the bloodstream.
Imbalance dangers: the physique controls manufacturing so deficiency is unlikey. Toxicity by way of supplementation has not been documented.
4. Vitamin D
Function: each types, D2 and D3, bind to calcium and magnesium to keep up electrolyte stability and bone formation. Also regulates the excretion of phosphates in urine.
Source: synthesized within the physique when the solar’s ultraviolet rays mix with a type of ldl cholesterol within the pores and skin; additionally supplied by high quality hay
Imbalance dangers: deficiency is seen solely when induced experimentally. Excess happens solely by way of over supplementation, with indicators together with calcification of coronary heart muscle and different comfortable tissues.
5. Vitamin Ok
Function: essential for blood clotting and the utilization of a number of proteins all through the physique
Source: K1 is present in recent and dried leafy crops, whereas K2 is synthesized by gastrointestinal micro organism. An artificial type, K3, is usually included in vitamin dietary supplements.
Imbalance dangers: deficiency happens solely when the intestine can not synthesize vitamin Ok or liver harm makes it not possible for the physique to soak up it. Some medication also can intrude with vitamin Ok manufacturing. Signs of deficiency embrace inside and exterior hemorrhaging. Overdose happens solely as a direct a results of injecting K2 when a horse just isn’t poor. Signs of toxicity embrace renal harm, laminitis and loss of life
6. Vitamin E
Function: works with the mineral selenium to counteract the doubtless dangerous results of oxygen byproducts of regular mobile metabolism often known as free radicals.
Source: rising forages, notably alfalfa, timothy and Kentucky Bluegrass. Grains comprise solely small quantities of vitamin E.
Imbalance dangers: deficiency can happen in horses who wouldn’t have entry to recent forage. Signs of deficiency in younger horses embrace speedy degeneration of cardiac and skeletal muscle groups. In grownup horses, sure muscle problems akin to equine motor neuron illness have been linked to relative deficiency. Excess has not been noticed
7. Calcium
Function: makes up about 35 % of your horse’s bone construction and is concerned in blood clotting, muscle perform and heart-rate regulation. The stability between calcium and phosphorus is essential in bone growth.
Source: Alfalfa is a wealthy forage supply of calcium containing 1.24 %, whereas timothy hay accommodates .43 % and oats solely .08 %.
Imbalance dangers: deficiencies end result from both low consumption or dietary imbalance that results in inefficient absorption. Calcium-deficit foals can develop rickets, a illness that weakens lengthy bones and enlarges joints. In mature horses, inadequate calcium could cause transient lameness. Excess has been linked to epiphysitis, a disturbance within the conversion of cartilage to bone; this has not been noticed, nonetheless, when calcium is balanced with different minerals.
8. Iron
Function: oxygen transport and hemoglobin manufacturing—iron is essential to a horse’s endurance potential. Although it’s common apply to present iron dietary supplements to equine athletes to boost efficiency, further iron gives no profit until the horse is poor.
Source: most forages and grains in ample quantities for horses in all phases of labor and growth. The horse’s physique can take up extra iron from his food regimen in instances of want.
Imbalance dangers: With uncommon exceptions, iron deficiency typically happens in horses who’ve had power or extreme blood loss or long-term parasite harm. When iron shops are depleted from the liver, spleen and bone marrow the horse turns into anemic with marked lower in train tolerance. Iron toxicosis is precipitated virtually completely by way of injected supplementation which bypasses the conventional absorption course of. Horses with excessive ranges of iron of their blood are extra liable to bacterial an infection. Foals who obtain an excessive amount of iron might grow to be comatose and die.
9. Phosphorus
Function: aids in metabolism of carbohydrates, fat and sugars, the utilization of nutritional vitamins, and kidney perform and cell restore
Source: hay and cereal grains comprise phosphorus, however the type present in hay is way more readily utilized by the horse. Hay grown in phosphorus-depleted soil accommodates low ranges of the mineral; excessive ranges are present in grass within the early phases of development.
Imbalance dangers: A scarcity of phosphorus from inadequate consumption or dietary imbalance causes bone demineralization and, in excessive instances, spontaneous fractures. The biggest harm in feeding extra phosphorus is from its interplay with calcium. At one time, “big head” illness, through which the bones of a horse’s head enlarge, was a typical affliction in these fed a substantial quantity of wheat bran, which may be very excessive in phosphorus and low in calcium.
10. Selenium
Source: Most forages comprise selenium, however the quantities differ vastly relying on the realm of the nation the place the forage was grown. For instance, the soils of Florida, Northern California and Western Oregon are low in selenium and produce selenium-deficient crops. Meanwhile, soil in components of Colorado, Montana, Wyoming and Dakotas comprise poisonous quantities of the mineral.
Function: works in live performance with vitamin E to scavenge damaging free radicals and help in muscle growth.
Imbalance dangers: A selenium-deficient food regimen leads to reproductive issues, immune deficiencies and, notably in foals, white muscle illness, the place the muscle groups grow to be weak and ineffective. Selenium poisoning often happens when a horse grazes on crops that comprise excessive ranges of the mineral. Horses affected by acute selenium poisoning might exhibit colic-like discomfort and elevated coronary heart and respiratory charges. Long-term grazing on crops that comprise excessive ranges of selenium can result in power toxicity and related anemia, lameness, a tough hair coat and brittle, malformed hooves. Untreated power toxicity will be deadly.
11. Sodium chloride (salt)
Function: essential for regulating physique fluids and conducting electrical impulses to nerves and muscle groups.
Source: Unfortified grains and forages comprise solely very small quantities of sodium, so supplemental salt—in block or unfastened type—is important for all equine diets.

Imbalance dangers: Without entry to supplemental salt a horse shortly turns into poor, notably if sweating closely or lactating. Slow-onset deficiencies can result in decreased sweating effectivity, urge for food loss, weak point and dehydration. A speedy decline within the physique salt provides leads to uncoordinated muscle contraction. Horses tolerate a excessive stage of salt if they’ve entry to recent water. Signs of salt toxicosis embrace colic, diarrhea and paralysis of the hind finish, and excessive instances will be deadly.
