Portuguese Horse Breeds Turn White

The Lusitano, a Portuguese horse breed known for its elegance and athleticism, has a unique genetic trait that causes them to turn white as they age. This phenomenon, known as "gray out," is a result of a recessive gene that affects the production of melanin, the pigment responsible for hair color.

History and Prevalence

The Lusitano breed originated in Portugal over 10,000 years ago, descended from the now-extinct Sorraia horse. Graying out has been a characteristic of the breed since its inception, with an estimated 90% of Lusitanos eventually turning white.

Age and Rate of Graying

Lusitanos typically begin to gray out between the ages of 5 and 10. The rate at which they turn white can vary greatly, with some horses becoming completely white within a few years, while others may take decades.

Causes and Genetics

The gene responsible for graying out in Lusitanos is known as the KITLG gene. It encodes a protein that plays a crucial role in the production and migration of melanocytes, the cells that produce melanin. A mutation in this gene causes a gradual loss of melanocytes, resulting in the horse's coat turning white.

Characteristics and Benefits

White Lusitanos are highly prized for their distinctive appearance and exceptional athleticism. They are particularly well-suited for equestrian sports such as dressage and show jumping due to their intelligence, trainability, and natural athleticism.
