Calcium –necessary for blood coagulation, cell membrane function, glandular secretion, temperature regulation, … Spring Grass. Hypocalcemic tetany in horses is an uncommon condition associated with acute depletion of serum ionized calcium and sometimes with alterations in serum concentrations of magnesium and phosphate. As in other species, the definitive treatment of equine hypercalcemia is treating or removing the underlying cause. If the amount of phosphorus exceeds that of calcium, the excess phosphorus will interfere with the absorption of the calcium, resulting in serious effects on the skeleton. The Merck Veterinary Manual was first published in 1955 as a service to the community. Intoxication with ergocalciferol or cholecalciferol has been reported in horses. What’s more, inordinate dietary calcium can expand the danger of renal calculi (kidney stones) in more established horses or enteroliths (intestinal stones) in horses of all ages.

Signs of an imbalance depend on which mineral is deficient. Diets too high in calcium may result in magnesium deficiency by creating an imbalance in the magnesium to calcium ratio. The horse must receive adequate quantities of calcium and phosphorus and in the correct ratio. Calcium has been fed as high as five times the horse’s requirement without any ill effects, provided that the P intake is adequate. About 99% of the calcium and over 80% of the phosphorus in the body are in the bones and teeth. This can make it a useful dietary addition to the feed for metabolic horses if they can tolerate it. In fact, mature equines require a one-to-one ratio, while growing horses need a two-to-one ratio of calcium to phosphorus. This can support healthy bones and overall well-being in your horse. It occurs after prolonged physical exertion or transport (transport tetany) … From developing new therapies that treat and prevent disease to helping people in need, we are committed to improving health and well-being around the world.

Ingestion of plants containing 1,25-dihydroxyvitamin D–like compounds (Solanum malacoxylon, S sodomaeum, Cestrum diurnum, Trisetum flavescens) causes typical clinical signs of vitamin D intoxication, including hypercalcemia. Not only is lucerne high in protein, it is high in potassium which can cause severe health and behavioural issues and it also contains large amounts of calcium without balancing magnesium, phosphorus or sodium.

If you take really high doses of vitamin A or D, you may absorb too much calcium. There are treatment methods that will help with reducing the calcium concentrations in the meantime. If the horse is eating 10 kg of high oxalate pasture containing 1.4% oxalates and only 0.3% calcium, the diet is also providing 140 … Horses with chronic renal disease frequently have high total calcium with a normal albumin, so presumably free ionized calcium is also high (free ionized calcium is not frequently measured in horses). The outcome will also be influenced by how advanced the condition is particularly with kidney degeneration or cancers. Keep an Eye on Calcium Balance.
