Oestrogen in mares is a crucial hormone for reproductive health. It regulates the estrous cycle and is responsible for the development of secondary sexual characteristics. Oestrogen prepares the mare's reproductive tract for ovulation and helps maintain pregnancy. It also influences behavior, making mares more receptive to mating. Understanding oestrogen's role can help in managing breeding programs and ensuring the mare's overall health.
