Horse Breeding
Breeding horses is the root of the horse industry, be it racing, show jumping, or just for the purpose of seeing the miracle of birth from the mare[s] that you own. Knowing how to breed horses and foal out mares, among other things that are involved in the topic of horse reproduction is important and can be asked and answered here.

A horse's penis can vary in length, but on average it ranges from around 18 to 24 inches in length when fully erect.
How long is a horses first cycle?
a horse is born as a foal, and that's when the cycle begins. a foal is weaned from its mommy when it is usually six months old. then its called a weanling. so the first part of it's life is six months long
Explain how a horse breeder might use selective breeding to produce horses that have golden coats?
There are two main golden coat producing genes, Cr (cream) and Ch (Champagne).
Both are dominant dilution genes.
Heterozygous Cream horses (Crcree) that are palomino colored will produce a palomino 50% of the time when bred to chestnut mares...bred to a palomino
mare the breeding will produce 25% cremellos 50% palominos and 25% chestnuts.
The use of a Homozygous for Cream stallion (CrCr)/a cremello will produce
100% palomino foals from breedings with chestnut mares.
The disadvantages of using the cream gene to produce gold foals is that the
homozygous individuals are not gold colored. This means that the color cannot
be designed to breed true in subsequent generations.
The advantage is that homozygous individuals are identifiable without genetic testing.
-----
A gold champagne stallion who is heterozygous for champagne Chchee will produce 50% gold champagne foals when bred to chestnut mares.
A homozygous gold champagne stallion will produce 100% gold champagne foals from chestnut mares.
The advantage to champagne is that a homozygous gold stallion or mare is gold colored with hazel eyes as the presence of two champagne alleles does not increase the level of dilution. This means that, over time, a breed could be
developed that is consistently gold colored 100% of the time.
There is a genetic test for champagne homozygousity,
If the only goal is to produce gold colored horses consistently the champagne
allele could be true breeding in as few as 2 generations using 2 homozygous
gold champagne stallions and as many gold champagne mares as could be
found to cross on them. Using this breeding format 50% of the foals produced would be homozygous gold champagne...culling the heterozygotes from the breeding program and back crossing them on the stallion who is not their sire would produce an F2 generation that was 100% true breeding gold champagne.
A search for additional homozygous gold champagne horses that could be
added to the breeding program to add genetic diversity could occur over time.
All this being said...breeding exclusively for color without regard for temperament, conformation or athletic ability is an error in judgement,
A horse with a roan coat color has a mixture of white and colored hairs from birth that remain the same as it ages. Roan horses can have blue roan (dark coat with white hairs) or red roan (chestnut coat with white hairs) variations.
Can a buckskin mare bred to a chestnut produce a gray baby?
This sounds unlikely to me.
A chestnut horse does not have any dilution genes in its coat. A chestnut with one dilution gene is a palomino, and with two dilution genes is a cremello.
A bay horse (non dilute) with one dilution gene produces a buckskin, and a second dilution gene produces a perlino.
If you breed together a non-dilute horse and a double dilute, you will always get the horse with one dilution gene. So if you breed a cremello to a chestnut you will always get a palomino, and if you breed a bay to a perlino you will always get a buckskin. As far as I know, if you breed a chestnut to a perlino or a bay to a cremello you will have a 50/50 chance of palomino or buckskin.
When you breed a chestnut and a buckskin one dilution gene is in play, from the mother who has it. The baby may inherit it or not. If the foal inherits the dilute gene it will be a buckskin or a palomino. If it does not inherit the dilution gene it will be chestnut or bay. In the diagram below, D is a non-dilute gene, while the lowercase d is a dilute.
MOTHER - buckskin Dd
FATHER - chestnut DD
FOAL: Possible combinations
DD (First gene from each parent), DD (First gene from mother, second gene from father), Dd (Second gene from mother, first gene from father), Dd (Second gene from each parent)
So this combination has a 50/50 chance of producing a dilute or a non-dilute.
The foal has a 25% chance of being each of these colours: Chestnut, bay, palomino, buckskin.
You must account for the variation in the shade of the coat also. If you get a very pale palomino, this can be similar in appearance to a very light grey horse. However, its genetics tell the real story. A grey horse is a single dilution gene on a black horse, with a double dilute of black being a colour known as 'smokey cream' which is indistinguishable from cremello and perlino. Many people think smokey cream, cremello and perlino horses are albino, but the true albino gene is fatal, with the foal aborting, being stillborn or dying a few days after birth.
If you bred your buckskin mare to a black stallion, you may get a grey baby, but there would only be a 25% chance once again, the foal could be bay, buckskin, black or grey. If you bred to a grey stallion, two dilution genes come into play and the foal would have a 50% chance of being either grey or buckskin, 25% of being black or bay, and 25% of being smokey cream or perlino. (Replace coat colours for breeding a buckskin to a palomino).
Answer 2:Grey is a dominant gene so one parent would have to be grey...no grey no possibility of a grey foal.
Keep in mind that the grey color is independent of the base coat colors...a grey foal generally has anywhere from a few to many white hairs in it's coat at birth
if it has the grey gene, barring that they show up around the eyes and or base of the ears when the foal begins to shed it's foal coat.
Why is the horse's penis size so big?
The horse penis is the size that is is, because it's a big animal, and just imagine if a stallion tried to breed with a mare, and his penis was as big as your finger. It would be hard to thrust his penis in, and it may result in injury to his penis.
What signs will a mare give when its about to give birth?
From the book Storey's Guide to Raising Horses by Heather Smith Thomas (Part III, Chapter 2, p. 377-78):
"About a month before the mare is to foal her udder begins to look fuller and larger, especially at night when she is at rest. Initially, this enlargement may recede during the daytime. About 2 weeks before foaling the udder will remain larger, filled with milk, and look shiny. A few days before foaling the muscles on each side of the tail around the pelvic bones become relaxed and droop away from the root of the tail. The mare's vulva may appear relaxed and swollen. There may also be a secretion from the teats.
"Secretion from the teats is one of the most common signals that foaling is imminent. The "wax" is formed by the congealing of secretions forced out of the end of the teat. Most mares wax within 24 to 36 hours of labor, but there are always exceptions. Some don't wax at all. Others wax for as long as 10 days before foaling. Still others may make up a large udder and leak streams of milk before they foal, with the milk dripping down their hind legs. The mare may leak milk foe just a few hours before foaling or for several days. A few mares foal without waxing of making much udder at all. Some have no milk when they foal; they come to their milk within a few hours after delivery. A mare may bag up, wax up, then stop waxing. The most predictable thing about mares is that they are unpredictable. If you're worried about a mare that is not 'going by the book,' have your veterinarian check her."
She will become restless, spins circles or lay down, breathe heavily and grunt
Every mare is different but a good resource is your vet . This website is also a good resource http://www.extension.org/pages/Horse_Behavior_at_Foaling_Time
Can you tell if a foal is a girl or boy before birth?
Not without a very careful and costly ultrasound examination.
What age do American Eskimo pups go into heat?
Puppies can go into heat anywhere between 6 and 14 months of age, my American Eskimo is 7 months old and is having her first cycle. if they have not had their first cycle by 14 months she should be taken to a veterinarian...
What is the average number of horse babies?
Usually horse only have one baby. Twins are rare and one is usually rejected by the mother.
What are the early signs of pregnancy in horses?
Mares frequently show no outward signs of pregnancy, other than missing an expected heat cycle. Some mares can even be racing fit well into pregnancy, up to seven to nine months. Most of the development of the foals occurs in the final three months of of the pregnancy. Some mares show significant weight gain, and some do not.
Mares can be examined with ultrasound as soon as 18 days after fertilization to confirm pregnancy. Blood tests can be used at about 120 days, and rectal palpitation can be used from approximately three months.
Are bay horses smarter than sorrel horses?
A horses personality trait is the way they act. The instuction that their brain is feeding their body. There appearance has nothing to do with the way they act of think. It is like a human with black hair being smarter than a human with brown hair. If your relating this question to the myth that blondes are dumb, or less smart than people of other hair colours, than neither of these two theories are true! Frankly, I'm 13 and have an 89% average thank you very much! ;)
-Quinnifer101
No of course not any horse can be as smart as any horse any color.
What is the speed of a quarter dropped at 6 feet?
It would be 9.8m/s. Try this experiment: drop a quarter and a pen at the same time from the same height. You will see that they both land at the same time even though their masses are a little different. That's because all objects fall at the same speed 9.8m/s no matter how high up they are when they're dropped or how much their mass is.
A2:A coin has abysmal aerodynamics but, after falling for only 6 feet, it will not have come anywhere close to achieving its terminal velocity and can, for all practical purposes be considered to be in freefall (assuming that the coin was, in fact dropped, and not thrown downward).Freefall is a condition where the falling object is not affected by aerodynamic drag. The acceleration due to earth's gravity (g) is 32.15 feet/second2
Re-arranging v = 1/2*g*t2, (basically, taking time out of the equation) you get:
v = (2*g*d)^0.5 (This is one way of writing "Square root of 2*g*d")
The velocity of an object in freefall for 6 feet at the earth's surface would be 19.6 feet per second.
What does a horses penis look like?
It's long with a rough-looking ball-like head (called the glans penis) at the end, kinda like a man's penis (only the man's glans is much smoother). A stallion's penis can measure up to 3 feet in length and is around 6 inches in diameter.
Referring to organisms for which sexual reproduction produces offspring with inherited traits identical to those of the parents. The organisms are homozygous for the characteristics under consideration.
Which is carried longer colts or fillies?
Colts and fillies have the same gestation period, so one won't be carried longer than the other.
How long do horses stay in heat?
Most mares will come into heat every 21 days. Usually 21 days after the day the mare first comes into heat, she will start into heat again, but some mares vary anywhere from 18 to 31 days in their heat cycles. Heat periods are generally longer earlier in the breeding season and many older mares have longer than average heat cycles.
The period of time when the mare is fertile and can conceive a foal generally only occurs 24 to 48 hours before the mare goes out of heat.
Why do mares squirt when in heat?
Mares may squirt urine when in heat as a response to increased sensitivity and swelling in the reproductive tract. This can be due to hormonal changes and increased blood flow to the area. It is a natural behavior and not a cause for concern.
Are carrots toxic to pregnant mares?
Horses love carrots. Just about all horses love carrots. They love them all the time. Save some sicko poisoning them, or feeding horses mouldy or rotten carrots, they are never bad for horses. They are very nutritious and if you feed a horse way too many carrots it will become fat. That's about the most danger they can have. I've never personally heard of a horse having a severe allergic reaction to carrots. I suppose it might be possible, but in this case it would affect the horse in question all the time, whether or not she was in gestation. Your pregnant mare will probably LOVE the extra attention if you spoil her rotten - carrots certainly won't hurt her.
How many times do horses have to be ridden a day?
Depending on the horse (breed, size, physical condition) and the reason why the person riding wants to ride (ie. pleasure, competition, dressage...) you can ride your horse for several hours a day. Remember that your horse needs breaks sometimes, just like you, so 5-10 min. rest every hour or so is probably a good idea. Always cool your horse down before turning it back out or returning it to its stall.
Ideally, you should only work a horse once a day, for a maximum of two hours (depending on what you are doing) and a minimum that depends on the horse (and what you are doing). Horses should not be worked every day, maybe about 5 or 6 days a week.
What animals are used to produce Premarin cream?
Premarin is a contraction for Pregnant Mare's Urine. It is used to treat menopausal symptoms in women, and is manufactured by Wyeth Pharmaceuticals (part of Pfizer since January 2009).
Harvested for their urine, the horses suffer terribly for the production of this drug. They are kept continually pregnant in stalls too small for them to even turn around in order for their urine to be collected by dirty, bulky tubing attached to their bodies. When they can no longer reproduce quickly they are sent to the slaughterhouse. Their meat is then sold for human consumption or dog food.
They have sex and the sperm goes into the egg of a female in it makes babies! ---- to have sex, or mate it can be assisted or just done by them selves! With assited horse mating there is a mare, or female horse, and a stallion, or breeding male horse. They hold on tight to the mare, and the stallion gets on the mares back and does his job! Someonespecial613 says: Well, my answer is a bit similar to their answers. You can take your mare to a stud or just use one of your own stallions (you definitely can't use a gelding!) If you use your own stallion then just wait until your mare is definitely ready for mating (see "how can I tell when my mare is ready to have a baby") and just leave them alone. Before you know it a new foal will be born to your herd! Someonespecial613 says:
The male horse will show great interest in the mare and vice versa. They mate and the sperm reaches the egg and penetrates it and a foal is conceived! Yeh, The male will put his front legs over the females back and they will have sex, the male's sperm will reach the female's egg and they will fuse together, and then it will grow and form a foal, and then the mother will push the foal out when it is ready to be born.
