The Equidae family is comprised of horses, donkeys, and zebras with only one existing family, Equus, which is made up of seven living species. The Equidae family most likely originated in North America, however, domestic zebras, horses, and donkeys now exist worldwide while wild horses and zebras exist only in Asia and Africa. All members of the Equidae family are herbivores, most of which graze on low quality vegetation to survive. In the wild Equidae, either live in close-knit herds led by a stallion or in fluid groups where the females float between males who possess resources. While only seven species currently exist, about 60 more species are known from fossils.

What are equines?

Equines are part of the mammal family, Equidae, that includes the modern horse, zebra, and ass. The equine family has 7 living species. Equines are odd-toed ungulates and have long, slender legs, long heads, long necks, manes, and long nails. All species of equines are herbivorous.

When did equines branch into horses and mules?

Mules are the result of breeding a female horse, and a male donkey. They were intentionally bred to bring out the best characteristics of horses and donkeys while eliminating any undesirable characteristics. Mules have been bred since 3,000 BCE.

What is the Coggins Test in equines?

The Coggins Test is a blood test in equines that is used to diagnose Equine Infectious Anemia (EIA). This disease causes equines to have fevers, anemia, edema, weight loss, and muscle wasting. Infected horses carry the disease for life, and there is no vaccine nor treatment for EIA.

Zony (Equus zebra x Equus caballus)
Scale illustration of an average Zony compared to a human

The Zony (Equus zebra x Equus equine) is the cross between a male zebra and the female pony. They are typically not large, but are strong. Zonies have the stripes of a zebra. The stripes do not cover their entire body, but only certain parts, like the neck or legs. When breeding the zony a medium sized pony is often preferred to create a riding zony. They are mostly found in zoos and are seen in the wild in Africa. They are herbivores and eat plant matter. The zony has a lifespan ranging between 15 to 25 years.

Zonies have a shoulder height between 43”–48” (109-122 cm), overall standing height of 46.5”-53.1” (118-135 cm), and body length of 55.1”-66.9” (140-170 cm). The weight of a Zony is between 500-700 lb (227-318 kg). Zonies have a typical lifespan of 15-25 years.
