When is a mare sexually mature?

A mare's sexual maturity usually occurs around 18 months of age, but can vary individually. This timing is often associated with the onset of estrus, the mare's natural reproductive cycle. It is important to note that sexual maturity does not equate to optimal breeding maturity. Many experts recommend waiting to breed until the mare is physically and mentally mature, which usually occurs around three years of age. Individual assessment and veterinary advice are crucial in making the best decisions for the mare's health and well-being.
