Goats undergo a strict breeding cycle that starts in adolescence and continues when the does, or female goats, come into heat, mate with the bucks, or male goats, and give birth. The result of the breeding cycle is a kid or baby goat.
Cycles of goat reproduction adhere to a regular, exact schedule. Goats are ovulating, polyestrous animals, with their breeding season peaking in the fall as the days get shorter. For the buck, breeding needs a short amount of time.
For the doe, however, it entails a brief mating period followed by several months of pregnancy, childbirth, nursing, and child care.
The sort of sturdy, attractive form you desire to see developing throughout your whole goat herd is what you need to ensure the buck you are mating your doe with possesses. Another guideline in this regard is always to breed to improve your herd. However, how often do goats come in heat?
What Is a Goat’s Heat Cycle?
For a goat to become pregnant, goats must be in heat, and this period is what we generally know as their estrus season. During the breeding season, goats cycle on average every 21 days.
Usually, this heat cycle only lasts one to three days, and they can breed at the midpoint. Furthermore, the window of opportunity for conception in females is also known as estrus.
You must breed your goats and care for them when they are pregnant if you wish to have babies. So, if you intend to breed your does, you must know every aspect of their cycles. And these include the goat heat indicators that will enable you to spot them when they are in heat.
In this manner, you may ensure a fruitful breeding season and avoid missing your window of opportunity. This knowledge is paramount, regardless of whether you raise a dairy goat or another breed.
Since goats can only reproduce while in heat, understanding the goat heat cycle is essential to getting good breeding. Once you know what to look for, identifying goat heat indicators is simple.

How Often Do Goats Come In Heat?
When it comes to breeding, there are two different varieties of goats. The ones that come in the heat all year round and those whose heat period is seasonal, consisting of dairy goats, breed only.
Among the first important things you need to know about goat breeding is what kind of goat you have. Most goat “Alpine” breeds only procreate during their designated breeding season. This breeding process occurs between August and December.
This heat period is certain, majorly for your large dairy goat breeds. These goat breeds include LaMancha, Saanen, Alpine, Oberhasli, and Nubians. Nubians may get coerced into continuous breeding, although their heat period might be very unpredictable.
However, your meat breeds, such as Boer, and smaller breeds, like Pygmy and Nigerian Dwarf, will breed all year long.
Do Goats Stay In Heat for a Long Time?
They are often only in heat for 48 to 72 hours, and to be willing to stand for the buck to mate, they must get it done at the appropriate moment during the cycle. We refer to this concept as the standing heat of the animal’s heat period.
During this time, the doe will exhibit only a few specific indications. But as the cycle progresses, they will exhibit fewer indicators as they enter standing heat and agree to mate by the buck.
How to Recognize a Heat Cycle in a Goat
Recognizing significant behavioral variations in your goat helps you determine if your goat is in heat. Except for Nigerian Dwarfs, does in all goat breeds start to go into heat in the fall and winter.
However, there isn’t even a set month or day, and although every female is unique, you can count on seeing them go into heat throughout the fall and winter. When a doe enters her estrous cycle, it is much easier to predict than when a doeling does.
During this time, they are louder than usual, and this trait shows as one of the typical behavioral patterns for them. The female is signaling her readiness for mating with a mating call.
She may also be aloof or affectionate, sometimes the reverse of how they behave. They tend to be loving, and their tails will start to wag. They are flaunting their smell, sometimes for their mate, and even discharge from the vulva may be visible.
Indicators of Heat in Doe
Some females exhibit minimal or no estrus, a condition known as silent heat. It is a reality that most goats exhibit some symptoms, but every goat exhibits a unique set of symptoms or a unique combination.
It’s best to note each doe’s behavioral pattern and the duration of her estrous cycle, so you will know what to watch out for later. Here are some indicators that a goat is in the heat:
Doe Becomes Chatty
In contrast to the majority of goats, does in heat may vocalize more than usual. Nubians can scream more often in heat since they are noisier than most other breeds.
Furthermore, a doe may make the same groaning and blubbering noises to notify the buck in a rut when she goes into heat.
Doe’s Character Evolves
A doe’s personality can change as a result of rage hormones. While aggressive, does may let other goats in the herd order them around without bucking. Submissive does may turn aggressive toward other does.
Urinates More

A doe in heat urinates more than usual, which is an interesting fact about goats. Pheromones are chemicals in a doe’s urine that alert a buck to the fact that she is ready for reproduction. A buck will shove his nose into the pee stream, elevate his head, and curve his upper lip to get a good whiff if one is there.
Vaginal Discharge
Under the doe’s tail may develop into a gel-like vaginal discharge, swelling, redness, and wetness. The hair at the sides of the tail should look moist or clump together to be the best indicator of vaginal discharge.
Bucks May Act Silly
You will be confident that a doe is in heat when she spends most of her time with a buck or if a buck is constantly nearby. The buck will act in other ways, including wagging his tongue and slapping his front hoof against the ground. Furthermore, when the buck senses the doe’s scent, he will start acting silly if he can’t see the doe.
What Does a Goat’s Gestation Period Entail?
After conception, the female goat goes through a gestation period. The gestation period lasts between 145 and 155 days, so keep that in mind when you plan your breeding. The average gestation period is 150 days or roughly five months for your standard-sized breeds.
The corpus luteum, a tissue on the goat’s ovary, produces the hormone progesterone in the doe. This hormone helps to maintain the pregnancy. However, the corpus luteum can get affected by stress, which can cause a pregnancy to end in miscarriage.
Furthermore, dog harassment and inadequate nutrition are common stressors for does. Others include being close to unusual animals.
In addition, it’s best that they avoid milk fever after delivery as the doe should consume more crude protein during the last month of pregnancy and less calcium. Don’t breed your doe in August if you live in a region with severe winters because you won’t want the kids born in a chilly, snowy month like January!
How Old and Large Should a Goat Be to Breed?
Size is more important when it comes to breeding than age. Before breeding, most of your standard-sized dairy goats need to reach a weight of about 80 lbs. A healthy, well-fed doe should reach this weight by roughly eight months.
However, some people like to wait until the goats are around 1 1/2 years old before breeding, but it is not essential if the goat weighs over 80 lbs. This fact holds water, particularly for the Nubians, who are peculiar for having slower growth rates than other races.
Doe breeding begins once the animal is closer to 1 1/2 years old because many of the does don’t gain weight in their first year. To ensure that your goats are healthy before breeding, ensure you have a dependable technique to weigh them.
How Long Will a Doe Continue to Bear Young?
A doe will remain in heat and breed for the rest of her life. Unlike humans, there is no menopause stage to pass through. If introduced to a buck, she will continue to reproduce and give birth to young until she passes away, as the “typical” life span is 11 to 12 years.
But, the cause of death for much older does can be related to kidding or pregnancy. So if you want to lengthen her life, you might choose to retire her from kidding at some point.
Conclusion
In goats, the estrous cycle lasts 18 and 24 days, or 21 days on average. Now that you know this, it’s best to set a suitable pattern for yourself, and your does to get the best out of the heat periods.
