ABSTRACT
It is thought that mares being 20 years old can still give birth to foals,
some individuals are even longer capable to be pregnant. However, each year
mare owners should realize that the older mare the more decreased horse fertility.
An aged mare that has recently had a foal has a greater chance to become
pregnant again than a mare of similar age that has remained barren despite being
bred over multiple oestrous cycles during the previous breeding season. The
fact that an older mare has never been mated previously (maiden mare) does
not indicate whether she will be fertile or not. Older mares may develop clinical
problems that may adversely affect fertility, which leads to consecutive stressful
and troubling interventions of breeders and veterinarians. So, strategies increasing
the probability of pregnancy in horses are essential for breeding management
and for sure will help to maintain animal welfare at high level.
