Why Are Horses Seasonal Breeders?

The horse is a seasonal breeder meaning that natural mating occurs during certain times of the year to ensure that the timing of birth is optimal for survival with regard to ambient temperature, food and water availability, and even changes in the predation behaviors of other species.

Do horses have a breeding season?

A mare’s reproductive system is affected by the seasons. Daylight is the controlling factor that causes a mare to come into heat in early spring. Breeding season kicks off in mid-February and runs through early June in the Northern hemisphere.

Why do animals breed seasonally?

Seasonal breeders are animal species that successfully mate only during certain times of the year. These times of year allow for the optimization of survival of young due to factors such as ambient temperature, food and water availability, and changes in the predation behaviors of other species.

Why are horses seasonally Polyestrous?

Mares are “seasonally polyestrous” because they have multiple estrous cycles throughout the spring and summer. Light is the controlling factor in mares coming into heat in early spring, although some mares may cycle during the winter months.

What makes a mare come into season?

There are two primary methods for inducing heat (ovulation) in the mare; these are manipulation of the photoperiod (light cycle) and chemical manipulation of the mare’s estrous cycle.

How long is horse breeding season?

During the breeding season, mares ovulate regularly every 3 weeks, but they are in heat and receptive to a stallion for only 2 to 8 days. Heat is generally longer early in the season (spring) and only 2 to 3 days in late June.

Are stallions seasonal breeders?

Stallions are seasonal breeders, therefore longer daylight and warmer temperatures will begin the process of readying the stallion for breeding season. Stallions should enter the breeding season in optimal health and body condition.

Why do horses fall after mating?

The most likely reason that mares lie down after mating is because they are overwhelmed and need to rest to bring their heart rate back down to normal levels. Stallions can be aggressive and hyperactive when courting and mating, and horses are socially sensitive creatures.

Can you stop a horse from coming into season?

Ways of regulating your mare’s heat cycle include: Oral altrenogest. Giving her this synthetic progesterone orally every day will reliably keep her from coming into heat. Once you stop giving it, heat cycles return.

How long do mares seasons last?

between 21-23 days
A mare’s cycle (oestrous cycle) lasts between 21-23 days. During this time she will have 3-8 days of standing heat where she would be receptive to a stallion for breeding.

Do mares get pain when in season?

Many mares become very sensitive when they’re in season but if she’s showing you she’s in pain when you ride her, it may be time to get her some help. When mares come into season, they’ll have significant hormonal changes that can result in discomfort and mood swings.

Can you ride a mare in season?

During the week when your mare is in heat, lower your training, riding and performance expectations. To continue to push your horse to perform during this time is quite stressful for her. During the week when your mare is in heat, you can work on things such as groundwork or simply give your mare a break.

What is a silent heat in horses?

Silent Heat Mares that exhibit no behavioral signs of estrus are called “silent heat” or “covert” mares. Usually, these mares have normal ovarian cyclic activity, but they lack the behavioral signs of being in estrus.

How many times a year can you breed a horse?

Breeding is all about timing. A healthy mare can go into estrus one to two times per month, and these are the times when she can be bred.

What months Can you breed horses?

The natural breeding season typically begins around mid-April. Beginning in late summer and early fall, the mare again will go into a transitional time similar to that seen in the spring. The periods of estrus and ovulations become more erratic and irregular.

What is the breeding season of mare?

Mares are highly seasonal when it comes to breeding, with their most fertile period, being from the end of winter (August) to start of autumn (March). For this reason, mares are termed “long day breeders” as the breeding season occurs during summer when daylight hours are longest.

How many times a year do horses go into heat?

For horses the natural breeding season occurs in the spring and summer. During this time, mares ovulate every 21 days and are in estrus for five to seven days. In the winter months they experience a period of sexual inactivity (anestrus).
