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.
At what age can you breed a horse?
Generally, assuming a filly is healthy and on a good plan of nutrition, she can be bred as early as two years of age, although many breeders suggest waiting until three years of age. Mares can continue to produce foals well into their late teens or early to mid 20’s.
How early can a filly get pregnant?
Fillies mature sexually as early as the yearling year, but it can depend on the season. Those born early in the year might cycle and be fertile as early as 14-15 months of age (May-June of the yearling year).
What is the best age for a horse to have a foal?
It does go down, but not considerably. It goes down considerably about 15 -16 and then again, that depends on the mare. I think the “optimum” age for a mare to have her 1st foal would probably be anytime between 4 and 12.
When can a mare have her first foal?
Perhaps the ideal age to breed a mare for the first time is when she is 3 to foal at 4, or 4 to foal at 5. However, there are many factors that can change that ideal age. Mares that are starting a show career may be in training at that time and should not be asked to carry a foal, grow and train.
Is 17 too old to breed a horse?
Generally, mares are past their reproductive prime when they reach 15 to 16 years old. There are mares that can carry and deliver healthy foals into their 20s, but the majority of them have had multiple successful pregnancies before.
Can you breed a 25 year old mare?
Older mares can become pregnant and carry a foal to term well into their twenties.
What time of day do horses give birth?
Mares typically foal very late at night through the very early hours of the morning. The Cooperative Horse Extension found 80% of foals were born between midnight and 6:00 am.
How do I know if my horse is pregnant?
A transrectal ultrasound of your mares uterus will give you the most information earliest in the pregnancy regarding if she is pregnant, how many days approximately is she in foal, and if there are any problems with the pregnancy. A blood test performed by your veterinarian can also determine if your mare is pregnant.
Can you use a human pregnancy test on a horse?
Human pregnancy tests -do not- work in equines. Human pregnancy tests tend to measure levels of Human Chorionic Gonadotrophin (hCG). Equines do not produce hCG. They produce Equine Chorionic Gonadotrophin (eCG, previously known as PMSG – Pregnant Mare Serum Gonadotrophin).
At what age do mares stop going into heat?
When does a mare stop having heat cycles? Again, this will depend. Some may stop at the age of eighteen, and a few may be younger. Some may also be older, even up to about twenty-two years old.
Can a filly get pregnant?
As the animals get older, there is great variability in the frequency of this behavior. Puberty for fillies will occur between 10 and 24 months of age, with the average being about 18 months. Under open-range conditions, it is rare for yearling fillies, or even for 2-year-olds, to become pregnant.
How many times should you serve a mare?
I personally prefer to follicle test, and serve once. Others don’t follicle test, and serve once daily for at least two days, then a day off then once more if the mare accepts. Alternatively, one breeder serves TWICE daily for three days (poor mare!!!)
Is 20 too old to breed a horse?
From ages 4 to 15, mares are in their reproductive prime. But from 15 to 20, their fertility declines, says McCue. Reproductive problems only continue to intensify in mares older than 20.
