The nutritional hyperparathyroidism in horses is a
metabolic disease associated with a deficiency of
dietary calcium and an alteration in the calcium
/ phosphorus ratio. The current management
habits can bring a predispostion to the disease.
The most common clinical manifestation is
the enlargement and deformation of the facial
bones, also including other problems such as
lameness (intense, intermittent and changing),
torn ligaments or tendons and epiphyseal
microfractures. All of these clinical signs occur as
a result of an initial hypocalcemia that leads to
the activation of the parathyroid hormone, which
extracts calcium from the tissue in order to get
a normocalcemia. Early diagnosis and proper
treatment helps patients recover. The aim of this
study was to describe the cases of three “Caballo
criollo colombiano” (CCC) mares with nutritional
secondary hyperparathyroidism, diagnosed by
obtaining fractional excretion of phosphorus >
0.5%, and the clinical symptoms oberved.
