Why do animals have low phosphorus?
The most common cause of chronic phosphorus deficiency is inadequate feed intake or inadequate phosphorus content in the diet over an extended time. This can be seen in sick animals that are anorectic for prolonged periods but also in grazing animals in arid regions with low phosphorus content in soil. Phosphorus depletion can also result from chronic renal tubular disease due to impaired renal reabsorption of phosphorus (eg, Fanconi syndrome) or primary or secondary hyperparathyroidism causing increased renal phosphorus excretion. Hypophosphatemia is a common finding in horses with chronic renal failure.
How to prevent hypophosphatemia in horses?
Currently, no effective approach to prevent hypophosphatemia and phosphorus depletion at the onset of lactation is known. Feeding higher amounts of dietary phosphorus during the last weeks of gestation is contraindicated, because it decreases the intestinal absorption rate of phosphorus and increases the risk of periparturient hypocalcemia. The dietary Ca:P ratio that appears to be essential in horses and other species to prevent secondary hypo- or hyperparathyroidism is not important in ruminants. Cattle tolerate Ca:P ratios between 1:1 and 8:1, provided the ration meets minimal requirements for both minerals. This peculiarity in ruminants can be explained by the high salivary phosphorus concentration (5- to 10-fold the concentration in serum) and the large amounts of saliva produced that alter the Ca:P ratio of the rumen content considerably.
Why do cows have hypophosphatemia?
The primary cause of this hypophosphatemia at the onset of lactation is often attributed to disturbance of the phosphorus balance, because large amounts of phosphorus are suddenly lost through the mammary gland.

This is typically achieved by switching to feed ingredients with higher phosphorus content or by using mineral supplements enriched with phosphorus.
What is the phosphorus content of dairy cows?
Research consistently confirms that a phosphorus concentration of 0.42% in dry matter is adequate for high-yielding dairy cows. Currently, no effective approach to prevent hypophosphatemia and phosphorus depletion at the onset of lactation is known.
How to diagnose hypophosphatemia?
Hypophosphatemia is easily diagnosed through blood biochemical analysis ; the blood phosphorus concentration, however, is a poor surrogate parameter to diagnose phosphorus deficiency. Due to the lack of a reliable parameter to assess the phosphorus status of an individual animal, indirect approaches, such as estimating daily phosphorus intake while taking into account phosphorus losses through the kidney, gut, and mammary gland, should be considered.
What is the role of phosphate in the cell membrane?
Phosphate is a major intracellular anion. It has a structural role in cell membranes, hydroxyapatite of bone, nucleic acids and phosphoproteins including adenosine triphosphate (ATP). Important in oxygen transports (2,3-diphosphoglycerate), second messenger systems (cyclic adenosine monophosphate), coenzyme systems (nicotinamide adenine dinucleotide phosphate). Important in the regulation of protein, fat and carbohydrate metabolism. Involved in the activation of vitamin D and calcium homeostasis.

Can a dog be hospitalized for hypophosphatemia?
If your dog is suffering from severe hypophosphatemia, your veterinarian will need to hospitalize the dog for immediate treatment. If the condition is caused by insulin therapy or intravenous nutrients and vitamins, these treatments will be suspended until supplemental phosphate has been administered for a few hours. If a condition of anemia is present, fresh whole blood transfusions may be required. Conversely, if your dog is only suffering a moderate case of hypophosphatemia, it may be treated on an outpatient basis as long as its condition is stable.
What happens to a dog with hypoparathyroidism?
In hypoparathyroidism, either lower than normal amounts of parathyroid hormone are secreted or the hormone secreted is unable to function normally. This, in turn, affects the levels of calcium and phosphorus. Smaller breeds such as Miniature Schnauzers are particularly susceptible, but other breeds may be affected.
What causes rickets in dogs?
Rickets is a rare disease of young, growing animals that causes soft and deformed bones. It is commonly caused by insufficient phosphorus or vitamin D in the diet. More rarely, calcium deficiency is to blame. An excess of calcium has caused rickets-like signs in some dogs.
What does hyperparathyroidism show in blood tests?
Tests on animals with primary hyperparathyroidism will show an abnormally high level of calcium in the blood. Other tests can be performed to determine phosphorus and parathyroid hormone levels. Because abnormally high levels of calcium in the blood may be associated with many other diseases, an animal must be thoroughly examined before confirming a diagnosis of primary hyperparathyroidism.
What is the cause of bone loss?

Phosphate levels in the blood can also drop suddenly if too much is redistributed into the cells through osmosis. This can happen after an insulin or glucose injection, or in refeeding syndrome when starving animals eat large amounts of food too quickly.
How to treat severe hypophosphatemia in dogs?
Severe hypophosphatemia is treated with intravenous fluids and phosphate ions. If your dog is very ill, this treatment can save his life, so it’s important to get to the veterinarian as soon as possible. Once the condition is stabilized, treatment will focus on the underlying cause.
How to determine electrolytes in a dog?
Electrolyte levels will be determined with a blood test. This will show the degree of hypophosphatemia, as well as abnormal levels of other electrolytes, especially calcium. The veterinarian will try to identify the underlying cause of the imbalance by testing for other conditions like diabetes and high parathyroid hormone levels. Concurrent symptoms, like vomiting or diarrhea, may help to determine the source of the problem. Other tests could focus on potential infections, autoimmune responses, kidney dysfunction or Cushing’s disease. X-rays or ultrasound could be necessary if a cancerous tumor is causing hormone imbalance, or to identify weak bones or fracture.
