What Month Do Horses Breed?

Mares are seasonal breeders and tend to only cycle from August/September to March/April each year. Gestation (pregnancy) lasts for an average of 340 days. Most mares are put in foal between September to January, with most foals being born in August to December.

What is the best season to breed a horse?

Horses are seasonally polyoestrous and cycle when the daylight is long – spring and summer. A mare’s cycle is approximately three weeks in duration, and for two to eight days your mare is in oestrus (commonly referred to as ‘in season’ or ‘in heat’).

What is the best time to breed a mare?

Optimal breeding is every other day while she is in estrus and before she ovulates. A mare will normally ovulate about 24 to 48 hours before the end of estrus.

How many times should a stallion cover a mare?

Q: How many times should a stallion cover a mare? Breeders recommend covering a mare every 48 hours while in heat, so two to three times per cycle. Some mares may need two or even three cycles to become pregnant.

How many mares can a stallion cover in a day?

It is carried out with military precision three times each day — at 6am, 11am, and 4pm — with both stallions covering three mares a day.

Can horses get pregnant in the winter?

In wild or feral horses, foals are rarely born in winter. Most mares show regular oestrous cycles only for a limited time period in spring and summer. With a pregnancy of 11 months, most foals are born at a time when temperature and nutrient supply would favour their survival in the wild.

Can a horse get pregnant in January?

In the northern hemisphere, mares show a lack of estrus from roughly November through to March. Even if they do show signs of estrus, they may not be ovulating and if they are bred they will not conceive.

What months are mares in heat?

The typical timing for a mare’s heat cycle is between April and early September. Between these months, your mare’s ovaries are either getting ready for the warmer seasons or slowing down for the colder winter months. Reproductive demeanors are noticed during the fertile period between April and September.

What is the 20% rule with horses?

The researchers found that an average adult light riding horse could comfortably carry about 20 percent of their ideal bodyweight. This result agrees with the value recommended by the Certified Horsemanship Association and the U.S. Cavalry Manuals of Horse Management published in 1920.

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 leave a stallion with mares?

Stallions can be kept with mares if the latter are in foal to the same stallion, are to be covered by the latter, or are not in estrus. They must always be separated at the onset of estrus [16]. However, one must be aware that there is still a residual risk of unwanted pregnancies.

Why do mares kick stallions?

A mare may kick at a stallion if it is not receptive to being bred. This defensive instinct may explain why some horses kick when they become alarmed—such as when a person, dog, or another animal ‘pops into view’ behind the horse.

What age does a colt become a stallion?

Colt: A male horse under the age of four. Filly: A female horse under the age of four. Mare: A female horse four years old and older. Stallion: A non-castrated male horse four years old and older.

Do mares carry colts longer?

Most mares will gestate longer than 11 months; however, this allows for fewer “surprise” foalings in undesirable conditions. Various traits can influence a mare’s pregnancy length. Studies have shown colts tend to gestate 2 to 7 days longer than fillies. The nutritional plane of a mare also influences gestation length.

Can you breed a horse in November?

In the northern hemisphere, mares show a lack of estrus from roughly November through to March. Even if they do show signs of estrus, they may not be ovulating and if they are bred they will not conceive.

Can a horse get pregnant in December?

Mares are seasonal breeders and tend to only cycle from August/September to March/April each year. Gestation (pregnancy) lasts for an average of 340 days. Most mares are put in foal between September to January, with most foals being born in August to December.

How long do horses stay fertile?

Peak fertility in horses occurs at approximately 6 to 7 years of age. Fertility begins to decline at around 15 years of age as mares become more difficult to get in foal and the rate of pregnancy loss increases.

Why is my mare in season in December?

During the winter when the ovaries are inactive, circulating levels of the hormone progesterone are very low. This lack of progesterone may lead to the mare appearing in season throughout the winter.

How many times a year do mares 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).

How many times can a horse get pregnant in a year?

Like cats, mare cycle during periods of long daylight length. This is thought to be an evolutionary development to ensure that the mare will give birth at the most hospitable time, this being in Spring. Given these factors, a mare can only have one pregnancy a year and will usually only have one foal in a given year.

Can a horse tell if a woman is on her period?

Women who have worked extensively with many different stallions on a regular basis tend to agree that, from their own experience, there’s no difference in how stallions behave towards them when they are on or off their period.
