Bone Demineralization

What is it?

Bone demineralization is the decrease, loss of, or removal of the mineral constituents of the skeleton. Temporary loss of bone mineral content in horses is generally associated with extended immobilization or a significant decrease in mobilization. This occurs when a horse enters a training program, often leaving a grazing situation and living primarily in a stall with short periods of work. Demineralization also occurs in horses that are restricted to stall confinement because of an injury.

Bone engages in a continuous cycle of remodeling that is influenced by many factors including age, season, nutrition, and exercise. The skeleton is made up of more than just calcium. Other minerals such as magnesium, sodium, and potassium are essential in bone-building processes. Aside from minerals, another major component of bone is the protein collagen.

Bone density is built and maintained when force or impact is applied. Several studies have shown the positive effect training has on increasing bone density in young horse. For instance, two-year-old Thoroughbreds that entered training with restricted free-choice exercise exhibited a drop in bone density, which later increased with the onset of exercise. However, heavy exercise was introduced after a period of demineralization when bone may have been at its most vulnerable, increasing the risk of bone-related injury.

To offset demineralization, horses in confinement should be supplemented with minerals necessary for proper bone maintenance.

DuraPlex™ is a proprietary blend of specific proteins, minerals, and vitamins scientifically proven to increase bone mineral density and bone area in both performance and growing horses.
