What causes hyperlipidemia in ponies?

Horses with insulin resistance, ponies, miniature horses and donkeys are at risk of hyperlipidemia (elevation of lipids in blood). Any event that causes a negative energy balance elicits excessive mobilization of peripheral fat to cause its levels to elevate in the blood.

How is hyperlipidemia treated in horses?

Treatment: supportive therapy, including fluid therapy, parenteral glucose administration (with or without insulin), partial parenteral nutrition, treatment of concurrent disease.

Can horses get Hyperlipaemia?

Hyperlipaemia occurs most commonly in fat ponies in late pregnancy and is rarely seen in larger horses. The syndrome has similarities with conditions in other species but the definitive aetiologies are not yet known. The condition in ponies is undoubtedly related to stress.

What causes high triglycerides in horses?

In horses, hypertriglyceridemia is usually due to metabolic syndrome, pituitary pars intermedia dysfunction (PPID, used to be called equine Cushing’s disease), and excess negative energy balance (ponies, donkeys).

Why are miniature horses at risk for hyperlipidemia?

Horses with insulin resistance, ponies, miniature horses and donkeys are at risk of hyperlipidemia (elevation of lipids in blood). Any event that causes a negative energy balance elicits excessive mobilization of peripheral fat to cause its levels to elevate in the blood.

How to know if your pony has hyperlipidemia?

Signs of Hyperlipidemia include: Complete refusal of all food. It is important to seek veterinary attention immediately if you suspect that your pony is suffering from Hyperlipidemia. One of the main symptoms of this condition is that the pony will refuse all food. Even if an owners tries to feed tempting food, he will show no interest.

How to treat hyperlipemia and hepatic lipidosis in large animals?

Blood glucose concentration should be monitored at least twice daily to ensure that euglycemia is maintained and that substantial hyperglycemia (≥180 mg/dL) is avoided. In camelids, partial parenteral nutrition with enteral supplementation can be used to maintain adequate energy intake and minimize further fat mobilization.

How can you tell if a horse has hepatic lipidosis?

Microscopically, there is variable fat deposition within the hepatocytes and epithelium of the bile ducts. The hepatic sinusoids may appear compressed and anemic with severe fatty infiltration. Gross and microscopic lesions of the primary disease process in ponies and horses may predominate.
