What causes hypocalcemia in horses?
Causes of Hypocalcemic Disorders in Horses 1 Diet - Either a lack of calcium in the diet or an overabundance of phosphorus can decrease levels of calcium in the blood; certain natural toxins, such as plants containing oxalates and black beetles, may also be inadvertently ingested, leading to hypocalcemia 2 Exercise-induced (transport tetany) - Hypocalcemia can be the result of electrolyte and acid abnormalities caused by the loss of calcium and other minerals through sweat after heavy exercise 3 Lactation (lactation tetany) - Creating milk requires large stores of calcium, and if sufficient amounts of calcium are not given at that time then the amount of calcium in the mother’s blood may be decreased 4 Primary hypoparathyroidism - Along with the hypocalcemia caused by a decreased functionality of the parathyroid, decreased levels of phosphate and magnesium may also be present 5 Renal failure - The kidneys are particularly important for the excretion of calcium for horses; kidneys that are functioning poorly may not be excreting enough calcium, causing it to build up in the blood 6 Sepsis - The connection between sepsis and lowered concentrations of calcium, known as hypocalcemia, is well documented in humans; the role of sepsis in lowering the concentration of calcium is imperfectly understood in animals but is a common cause of hypocalcemia in horses with acute gastrointestinal diseases
What causes calcium to be inaccurate?
Hypocalcemic disorders , caused by an overabundance of calcium contained in the bloodstream, also known as hypocalcemia, is usually diagnosed during comprehensive blood testing including a biochemical profile and complete blood count. Many factors can cause an inaccurate calcium test, however, and these should be taken into account when reading the results. Certain anticoagulants that contain citrate, EDTA, fluoride chelate calcium, or oxalate, for instance, can cause calcium levels appear to drop. Other disorders and diseases can cause erroneous results as well; abnormalities in either the albumin or protein concentrations can have an effect on the amount of calcium, erroneously increasing or decreasing the amount of calcium registered in the circulatory system, although there is less correlation in horses than in most other species. High levels of fat in the blood or the rupture of red blood cells may also falsely raise total calcium levels. Acidosis is another condition known to interfere with blood tests that involving calcium; although overall levels of calcium will be accurate, the ionized calcium is increased due to a decrease in the amount of calcium that is bound to protein.
Does phosphorus decrease calcium levels?
Diet - Either a lack of calcium in the diet or an overabundance of phosphorus can decrease levels of calcium in the blood; certain natural toxins, such as plants containing oxalates and black beetles, may also be inadvertently ingested, leading to hypocalcemia

Why do horses have big heads?
Interestingly, many horsemen report increased incidence of calcium deficiency and cases of big head within a few weeks of rainfall. It may be that rainfall triggers new growth that the horses find more palatable, or that the increased moisture increases the oxalate content of tropical grasses.
How does oxalic acid bind to calcium?
Oxalic acid binds calcium by forming crystals of calcium oxalate in the grass stem and leaf in much the same way as phosphorus (phytic acid) forms phytates and prevents calcium absorption. Oxalic acid forms compounds with many elements to produce oxalates, some soluble and some insoluble. Levels of oxalates vary between plants, ...

Is hypoparathyroidism a rare disease in horses?
Primary hypoparathyroidism is a rare but well documented disorder in horses. Affected horses have clinical signs consistent with hypocalcemia (ataxia, seizures, hyperexcitability, synchronous diaphragmatic flutter, tachycardia, tachypnea, muscle fasciculation, and ileus). As in other species, the diagnosis is based on the finding of low serum concentrations of calcium and PTH with high levels of phosphorus. As described above, treatment with intravenous and subsequently oral calcium combined with large doses of vitamin D should result in the remission of clinical signs associated with hypoparathyroidism.
What are the most common deficiencies in horses?
