How long can you keep a stallion to breed mares?

In fact, some owners will keep their stallion to breed mares until he is 20-30 years old, especially ones that earn them hefty fees. It all depends on the horse, his sperm production, how well his offspring are doing, and other aspects of life that might be affecting him.

When do horses stop breeding?

In general, female horses can breed until they are 25 years old, and male horses can breed up to 30 years old. But some horses may stop breeding either much younger or older depending on their health, fertility, and history.

And you don’t have to stick to a gentle walk/trot session. Up to about eight months of pregnancy you can continue a normal workout and even jump and compete, says Aurich. Some Thoroughbred mares continue racing until very late term, adds Johnson.

How long can a stallion keep a mare in heat?

Stallions can bring a mare in heat within a few hours if it is the right season. I usually leave my stallion with my mare for about 3 or 4 days. That usually works, but do it twice within a few weeks, just to be sure, and if she doesn’t come back in heat then he probably got her bred.

Can a stallion breed a mare when he’s a year old?

A stallion can successfully breed a mare when he’s a year old. However, this should never happen. A stallion should be the best of the best, and have won recognition as a superior specimen (either through racing or another discipline), have outstanding conformation, and have a Kind and willing temperament.

If you don’t already have a place for your mare to foal, she’ll need a large stall, at least 12 by 12 feet, that is deeply bedded and safe for the foal.

How does season affect the reproductive performance of the stallion?

As in the mare, reproductive performance of the stallion is affected by season, regulated by the influence of daylight hours on hormones. During the breeding season, April through August, stallions are more productive than in the fall and winter months in several ways:

What determines the fertility of a stallion?

The fertility of a stallion depends on several factors: Total sperm production. Percentage of motile normal sperm. A large daily sperm production will be ineffective if the sperm are not motile.

What controls the temperature of a stallions testes?

A stallions testes are housed in the protective covering of the scrotum which regulates the temperature of the testes. Since stallions need approximately 57 days to produce mature spermatozoa, injuries and infections that cause abnormal rises in temperature can have long-term effects on the stallion’s breeding season.

What is stallion fertility and why is it important?

Stallion fertility is important because it means foals on the ground, a successful and profitable breeding operation, and the continuation of a particular stallion’s genetics.

What factors affect breeding stallions’ sperm quality?

Breeding stallions are sensitive guys. Anything from ambient temperature to body weight can affect their semen quality. In this article, we’ll describe those factors and 12 more that can impact fertility. Three veterinarians well-versed in stud health will help: Edward Squires, PhD, Dipl.

How do you know if a horse is infertile?

If a stallion spikes a fever just before or during breeding season or when being collected, he might be infertile until new sperm completes its production cycle. “It takes about 60 days for sperm development, so the stallion should be checked about 60 days after the fever incident to see if he is producing normal sperm again,” says Sheerin.

How can we improve the fertility of affected stallions?

Additionally, there is some evidence to suggest that sperm processing techniques can be used to improve the fertility of affected stallions. For example special gradients can be used to separate ‘good quality’ sperm from ‘poor quality’ sperm thus allowing us to breed each mare with semen that is enriched in sperm that are likely to be more fertile.

Does stress affect semen quality in horses?

“It often depends on the duration of the stress, so we need a good historical perspective when a stallion comes in for an examination and has reduced semen quality,” says Varner.

What happens if a stallion is stressed during breeding?

If a stallion becomes stressed or ill, causing sperm production to cease or resulting in deformed, infertile sperm, the effect on fertility will not be seen until 60 days later. Handling and care. Mistreatment during breeding will affect the stallion’s behavior and thus desire to mate.

How important is the health of the stallion in the breeding shed?

However, the concern in the breeding shed involves more than just the mare and her reproductive health. The health of the stallion, especially as it relates to fertility, figures strongly into the equation.

How many mares can a stallion breed to get pregnant?

An evaluation should estimate the stallion’s fertility when compared with other stallions with known fertility. Stallions should be expected to achieve at least a 75% pregnancy rate when bred naturally to 40 mares or 90% pregnancy rate when bred artificially to 120 mares.

What to do if your horse is not producing normal sperm?

This technique can be quite expensive, but can result in pregnancies from stallions that are producing very low numbers of normal sperm. Another excellent management tip is to freeze sperm from fertile stallions while they are younger and before this problem begins.

What are the most common behavior problems in stallions?

Loss of sexual interest and arousal is the most common behavior problem in stallions. Rough handling, a painful or traumatic breeding experience, excessive punishment or severe discipline can discourage a stallion from expressing natural sexual urges. Also, breeding fatigue may occur if the schedule is to strenuous for a prolonged time period.

What happens if a mare has a bad stallion?

Having one mare who is a poor reproductive performer is unfortunate, but one poorly managed stallion can have a disastrous effect on a breeding program. Because of the impact that the stallions can have on the productivity of a farm, they are judged more critically and culled more extensively than the brood mares. 1

Why is it important to keep a stallion fit?

The goal is to keep a stallion fit for the breeding shed, not the racetrack, so that he has a good attitude toward his daily duty of covering mares. The personnel responsible for exercising stallions must be good horsemen or horsewomen so that overwork and injuries can be avoided.

What happens if a horse stallion has poor body condition?

If a stallion has poor body condition, that may indicate inadequate nutrition or improper management. Because poor body condition of stallions may have detrimental effects on semen quality, do not evaluate such stallions for breeding soundness until the condition has been corrected and at least 60 days have passed.
