Foals are usually born in the spring. The estrous cycle of a mare occurs roughly every 19–22 days and occurs from early spring into autumn. Most mares enter an anestrus period during the winter and thus do not cycle in this period. [54] Foals are generally weaned from their mothers between four and six months of age. [55]
Free-roaming mustangs (Utah, 2005). Horse behavior is best understood from the view that horses are prey animals with a well-developed fight-or-flight response.Their first reaction to a threat is often to flee, although sometimes they stand their ground and defend themselves or their offspring in cases where flight is untenable, such as when a foal would be threatened.
A mare is an adult female horse or other equine. [1] In most cases, a mare is a female horse over the age of three, and a filly is a female horse three and younger. In Thoroughbred horse racing, a mare is defined as a female horse more than four years old.
A mare may be in heat for 4 to 10 days, followed by approximately 14 days in diestrus. Thus, a cycle may be short, totaling approximately 3 weeks. [21] Horses mate in spring and summer; autumn is a transition time, and anestrus occurs during winter.
For comparison, the researchers also sequenced the genomes of a 43,000-year-old Pleistocene horse, a Przewalski's horse, five modern horse breeds, and a donkey. [41] Analysis of differences between these genomes indicated that the last common ancestor of modern horses, donkeys, and zebras existed 4 to 4.5 million years ago. [40]
The possible causes of the extinction of horses in the Americas (about 12,000 years ago) have been a matter of debate. Hypotheses include climatic change and overexploitation by newly arrived humans. [22] [23] Horses only returned to the American mainland with the arrival of the conquistadores in 1519. [24]

Mares are dewormed a few weeks prior to foaling, as the mare is the primary source of parasites for the foal. [16] Mares can be used for riding or driving during most of their pregnancy. Exercise is healthy, though should be moderated when a mare is heavily in foal. [17]
