Signs of heat and features of the mating process of pigs

“Hunting” in pigs (the desire to mate) is the time of ovulation, when the sow needs to be brought together with a boar for sexual intercourse. You can also use the method of artificial insemination in order to further produce piglets. Let's consider when this period begins in animals, and how many days a pig usually walks.

Characteristic signs of the heat period in pigs

The onset of the female's attraction to the male occurs at intervals of exactly three weeks and lasts up to three days. In certain representatives of livestock, heat begins to manifest itself during the period of gestation, which makes it possible to carry out their re-fertilization.

The initial ovulation phase can occur in pigs that are 5 months old. But mating with different species of individuals is prohibited, because many pigs at this time have not gained weight for a successful pregnancy and development of offspring.

Planning the initial mating is permissible when the pig approaches 10-12 months of age. The sow selected for insemination must closely match the characteristics of her breed and must be free of any significant defects or signs of disease. To make sure that the pet does not have dangerous diseases, it must be examined by an experienced veterinarian before fertilization.

When does puberty occur in pigs?

Sexual maturity and biological readiness for mating occurs in animals at the age of about 6 months. However, despite the ability to fertilize, their body is still underdeveloped and offspring may be weak and few in number. In addition, early birth leads to weakening of females and a delay in their development.

Depending on the breed of pig, the first mating usually occurs between 9 and 10 months of age. Here it is important not to overexpose the pig, since after the age of 14 months there may be reduced fertilization and low milk production of the uterus.

Important! If you press your hand on the back of a pig during the hunt, it will remain motionless and will resist attempts to move it from its place.

The cyclical occurrence of hunting

In pigs that have grown to the point of puberty, heat comes systematically at intervals of 18-24 days. If there is no insemination during hunting, this process can be duplicated only after 21 days. Deviations occur in cases where the pig does not have enough weight for the positive course of pregnancy and its successful completion, or hunting is observed at different periods without regularity.

The farmer should not mate pigs with these problems. If an animal has these problems, the breeder needs to focus on a nutritious diet. Perhaps the females are malnourished. To rectify the situation, you can make feed yourself.

In a number of females, sexual desire may make itself felt at the time of bearing piglets. Then the transfer to a healthy and young male is allowed to be done again. After this, the farmer can expect two or three pig births at close intervals.

Estrus in pigs and its features

The readiness of females to mate occurs in two phases: excitation and inhibition. The first stage is characterized by estrus and sexual arousal, while the second stage is characterized by attenuation.

The duration of estrus can vary, approximately it lasts from 3 to 10 days and includes four periods: proestrus, estrus, metestrus and diestrus. Proestrus, which is the first of these, marks the beginning of estrus. At this moment, the female demonstrates aggressive behavior, she loses her appetite, she constantly squeals and rushes at other pigs.

In young pigs, pronounced swelling and redness of the genital organs is observed; in sows that have given birth, this symptom is not so pronounced.

The period of heat itself, or estrus, is characterized by the fact that the female often freezes in place, begins to freeze when pressure is applied to her back and raises her ears. Redness of the genital organs and their swelling subside. This stage is one of the peak stages in estrus; it lasts only one day, maximum two. It is at this moment that mating should take place.

At the metestrus stage, the female calms down and demonstrates calmer behavior. Her genitals decrease in size and turn pale. The final phase is diestrus, a period in which the pig completely calms down and the estrus ends. It lasts about two weeks, after which the cycle repeats again.

Signs of the hunt

You can see how hunting resumes in females by certain manifestations:

• an increase in the size of the genital loop and milk nipples;
• frequent emptying of the bladder;
• aggressiveness of the animal;
• the presence of abundant viscous contents from the genital organs;
• lack of desire to eat food, not associated with diseases of the digestive system.

To determine the first moments of heat in a sow, it is enough to apply light pressure on her posterior gluteal region. If the female reacts to such a movement in any way, we should assume that the hunt has not begun. When the female behaves calmly and resists the moment of a forced attempt to move her, this indicates that it is time to place her with the boar.

How to provide the pig with the necessary conditions

The period of sexual desire is counted from the first day of hunting. Pre-hunt lasts for 2 or 3 days. Prolonged hunting exhausts the female, and she becomes too lethargic. Pro-estrus does not last more than 200 hours. Over the years, the hunting period for adult females decreases. The older the sow, the faster her heat ends.

Experienced pig breeders can recognize a pig that is ready to hunt even by the characteristic sounds it makes. In most cases, the genitals of mumps swell. It is extremely rare that the female continues to behave without changes. Before mating, a discharge must appear from the pig's genitals, otherwise mating with the boar will not occur. In no case should an animal be allowed to become injured, so you should not allow a male to approach a sow without primary signs.

If you introduce a male pig to a fertilized pig, she will not react to him at all. If other sows start to heat and try to jump on the expectant mother of piglets, she resists and shows aggression.

The genitals and mucous membranes change color. The external genitalia wrinkle a little and turn pale. Post-hunting takes only a few days, during which the pig calms down. It is important for both experienced farmers and beginners not to scare the animal or take decisive action without signs that the pig is ready to reproduce. Careful preparation and further care will help the sow bear healthy and full-fledged offspring.

The final stage in pork production is the slaughter of pigs, which needs to be carried out correctly. To do this, it is important to prepare for this process in advance, and the preparation should be theoretical in nature. However, pigs can be slaughtered with the help of a specially trained person with extensive experience.

Matching

The success of mating and the birth of healthy piglets depends on the correct choice of pigs for fertilization. Moreover, experts have certain requirements for animals of both sexes. When choosing a sow suitable for mating, you need to focus on the following significant points:

• the selected female must correspond to her breed in terms of external data and existing characteristics;
• the animal must be healthy and free of any defects;
• The sow must be at least 9 months old.

In the case when a female gives birth not for the first time, her state of health should be taken into account, as well as the number of piglets surviving after birth.

The choice of boar is carried out in more detail. In this case, the farmer must take into account important points:

• the breed of boar and sow must be the same;
• absence of animal diseases;
• age limit - boars no more than 3 years old are allowed to mate;
• The appropriate weight of the boar should be selected based on the body weight of the female.

Important! It is recommended that the sow be mated with boars kept on other farms. When mating pigs living on the same farm, there is a high risk of giving birth to piglets with certain defects or diseases.

First of all, you need to take into account how productive the boar is before replacement. In the best case, it is necessary to submit the boar's sperm for testing. However, such a procedure is difficult for an ordinary breeder who does not have a large farm.

As an alternative, piglets previously sired by this male should be examined. To obtain the necessary information, you can ask the farmer questions about the special characteristics of the animal.

How to choose the right pair?

This aspect deserves special attention. You already know how many days a pig walks and by what signs you can determine the beginning of the period of sexual desire. But the success of breeding domestic animals and the health of the young livestock depend on how well the sow was selected. During the selection process, the following nuances must be taken into account:

• compliance of the animal with all the characteristics of a particular breed;
• good health and absence of any pathologies and diseases;
• optimal body weight and degree of fatness;
• age.

It is also worth considering the number of previously produced offspring and the quality of the offspring. If the piglets were weak and sickly, then it is better not to use such a female for breeding pigs. In order for a gilt to mate during heat to be successful, the boar must also meet certain criteria. Among the most important nuances are the following:

• similar breed as the sow;
• good physical development;
• age no more than 3 years;
• ideal size to weight ratio.

Experts in the field of animal husbandry say that it is better to choose a male and a female from different farms. If they are blood relatives, then there is a high probability of having weak and defective offspring.

Methods for determining and duration of farrowing

After the initial symptoms of heat appear, the pigs begin estrus, which lasts 2-3 days. At this time, animals should be inseminated artificially or naturally. If insemination is successfully completed, the pig will not go into heat next month. The female's pregnancy lasts from 114 to 117 days. If signs of heat appear after three weeks after natural insemination, the female must be mated with the boar again.

Not every female is able to bear offspring. Before introducing animal sperm into the female genital tract using an artificial method, the veterinarian must carefully examine the pig and, if necessary, conduct mandatory research. A pig that does not conceive after 3-4 inseminations also requires examination by a veterinarian. If it is confirmed that the female is unable to give birth, she is slaughtered.

How to stop sexual estrus in a pig

If the breeder does not plan to mate the pig when the heat comes, you can use traditional methods to reduce this condition. Among them:

• Laying a copper plate on the bottom of a wooden trough with water. Allows you to reduce the female's attraction and calm her down.
• Adding Swinsychron to the feed . It must be used within 18-20 days. The drug should be added to food when the first signs of heat appear.
• Adding mash to pig feed . In this case, the animal will sleep more. This method must be used before the end of the hunting period.

The presented methods are safe for pigs; they only have a temporary effect on the female’s body. In order to have a successful mating during the next hunt, the breeder only needs to eliminate the influence of these factors on the animal’s body.

You should not use (inject) heat suppressants for pregnant pigs. In this case, the breeder just needs to wait 2-3 days until the hunt goes away on its own.

Hunting dates

It is important to know how many days a pig walks. Features that influence the duration of the hunting period may vary. However, the main one is the age of the pig.

Young females are in heat for about 1.5 to 2 days, but sometimes this time lasts up to a whole week. As a sow ages, the activity of the reproductive system decreases, and with it the duration of sexual heat. The end of the mating period is indicated by the habits of the animal itself. The pig behaves calmly and does not pay attention to the boars.

Symptoms of hunting in animals will allow us to determine the beginning and end of the gestation period. According to experts with experience in livestock farming, the breeding season often lasts no more than 2 days. After their expiration, the individuals begin to live as before. But it is also worth considering many factors that play an important role. In order for a pig to be prepared for mating, it is necessary to evaluate the overall picture of its condition, and not focus on individual factors.

Basic indicators of puberty

Let's look at this in more detail. Before finding out how many days a pig walks, let's first understand the signs that will help determine puberty in animals. According to experts, representatives of this group of artiodactyls are ready for mating as early as 6 months. At this age, pigs are already fully formed and ready to bear offspring. The beginning of the period of sexual desire can be judged by some behavioral changes.

In sows these are:

• deterioration or complete loss of appetite;
• increased excitability;
• periodic change of location;
• increase in size and change in color of the genital organs (becomes more saturated);
• constant squealing.

Among the main characteristics in males are the following:

• increased urge to urinate;
• constant grunting that does not stop for several days;
• the boar constantly rubs against surrounding objects;
• increased aggressiveness.

But how many days does a pig walk? The signs of heat listed above will allow you to determine the beginning of the breeding season. As for its duration, it all depends on many factors. This will be discussed in more detail below.

How to control deadlines

One individual can experience the period of ovulation and its stages of development in completely different ways. Large peasant farms developing in the field of livestock farming pay close attention to signs indicating the initial symptoms of the hunting period in females. If all conditions are met, the farmer will be able to increase the herd through successful breeding. Moreover, it is important to take measures to prevent the pig from wandering around and breeding without control.

Carrying out artificial fertilization allows you to control the process of sexual hunting. Farmers who raise livestock for commercial purposes often deviate from mating naturally. Semen is collected from existing boars on the farm, and it is also purchased abroad. The reason is to improve the quality and taste of meat products.

Experienced breeders believe that when a pig does not have the opportunity to estrus, this is primarily reflected in the offspring. However, this opinion is incorrect, since the quality of meat products largely depends on the use of growth stimulants.

Important! Improper nutritional diet of the female leads to weight gain. As a result, there is a delay in estrus.

If there are boars in the pen, sows reach puberty faster, and hormonal levels change. The activity of the genital organs also changes, a repeated course of processes and the formation of cycles are observed.

It is not difficult to calculate the cycle time: it will be from the first days of one heat cycle until the next one. The duration of estrus in mature sows ranges from 3-10 days.

The cycle consists of the following phases:

• excitement (proestrus);
• hunting (estrus);
• calm (postestrus);
• tranquility (diestrus).

Many people are interested in whether it is allowed to slaughter an animal during the period when sexual heat is observed. In fact, slaughtering pigs during this period is not recommended, since due to excessive production of hormones in a living body, the quality and taste of meat products will decrease. In its structure it will be hard, with an unpleasant odor. 7-10 days after the end of the ovulation period, the pig is allowed to be slaughtered. This time is enough to remove hormones from the animal’s body that lead to a deterioration in the taste of meat products.

It is necessary to keep under control all periods of hunting. This is necessary for a clear understanding of when it is permissible to slaughter an animal. Lack of appetite and aggressive behavior will significantly complicate overall preparation. It will be difficult to keep the pig in one place. Some breeders prefer to inseminate females while they are actively attracted to males. As a result of the acceleration of metabolic processes in the body, the pig gains weight. At the end of the month the animal is slaughtered.

Preparing for mating

At what age does a pig start to walk? An important stage in preparation for the moment when the sow is ready to breed is the selection and separation of young animals. Not every female is selected to nurse future offspring. If the farmer manages to choose the right female, at the right age she will be able to give full-fledged and healthy offspring. After birth, the young quickly gain weight. At this stage, it is important to choose the right diet for the pigs (fed artificially) and provide them with proper care.

The future sow should have a calm disposition. An overly active pig can trample the brood and harm the pig. In aggressive individuals, the maternal instinct is the least developed.

The sow is kept separately from other individuals, both pigs and wild boars. A separate balanced diet is organized for the expectant mother. The pig should gain weight moderately, without excessive growth of the sebaceous layer. The sow's enclosure is cleaned at least twice a week.

Mating is a natural process in the life of every animal, but the result will depend only on the farmer. After and before mating, the sow should be provided with proper and proper care, otherwise the piglets will be weak. A pig with the following parameters is suitable for a sow: moderately well-fed, calm and with all functional nipples. If the farmer managed to select a suitable female, then the piglets will be the strongest of the entire litter.

Signs that a pig is walking or ready to breed are hard to miss. Such a sow behaves very actively and playfully. If the farmer has not previously had to deal with changes in the behavior of the pig, then the main sign that the sow wants to walk is rapid weight gain and excessive activity. Piglets from a healthy female are born without complications. Just one sow can give birth to up to 12 piglets at a time. After selecting a female, you need to pay attention to the qualities of the boar, which will produce healthy offspring. When is the right time to breed pigs?

Synchronization Methods

In females, oestrus synchronization is carried out differently. The following methods provide the effect:

1. After the sows are weaned, Follimag is administered to her in the amount specified by the veterinarian. The medication is to be administered intramuscularly. If the pig begins to show initial symptoms of ovulation, about an hour before mating, the veterinarian administers a drug called Surfagon. The technique can be used as in a situation with breeding with a boar, or before performing insemination using an unnatural method.
2. Injections of Follimag and Suffragon are allowed for females whose hunting has not resumed two weeks after the removal of their piglets. This technique is allowed to be used if the majority of the livestock has entered the hunting stage at a suitable time after the removal of the offspring.

Practicing both methods in practice is allowed only after the recommendation of a veterinarian. It is prohibited to use hunting synchronization techniques on your own, because sometimes they can be harmful to the animal’s body condition.

conclusions

1. Hunting in pigs can begin (come) already at the age of 5 months. However, for mating it is necessary to take animals over 10 months old that correspond to the species characteristics.
2. Hunting occurs every three weeks. It lasts (frequency) on average 2-3 days.
3. You can determine (distinguish, know) the onset of heat by the swelling of the pig's nipples and genital loop, the appearance of abundant mucous secretions, the pig's restlessness, as well as the animal's refusal of its usual food.
4. Synchronization of hunting can be carried out by introducing Follimag and Suffragon to the animals.
5. If the animal has not started to heat, it is recommended to introduce young boars into the pigsty (cover the pig), improve the feeding of the animals, and also use pathogen sprays. The latter are most effective if artificial insemination of a pig is planned.
6. You can discourage an animal from going for walks by adding mash or special preparations to the food. This can only be done on the recommendation of a veterinarian, so as not to harm the animal.

What to do if the boar does not cover the female

In a situation where a mature animal has no interest in mating, it must be taken to a veterinarian for examination. When certain diseases are detected in a pig, it must be treated with certain drugs according to a treatment regimen. If the veterinarian does not detect disease in the animal, young boars should be moved to a room with females. This will give an impetus to the start of heat in sows. Another way to induce heat is to use Oxytocin.

At the same time, it is necessary to provide the animals with daily walks in fresh air. Pigs with greater weight lose sexual activity, so they need to exercise more. Frequent visits to outdoor pens will help reduce their increased body weight.

Heat can be stimulated using certain stimulants made from the urine of a stud boar. The products are sprayed on the territory where the female is constantly located, and her period of heat has not begun. This method is considered to be the most effective. It is often used in large farms involved in livestock breeding.

Why don't pigs go for walks?

Main reasons and solutions

If you already understand how to find out when a pig is walking (the signs are described above), but hunting does not occur, you need to immediately find out the reasons. A long absence of the sexual cycle negatively affects the reproductive system of sows.

The reasons for the lack of repeated heat and slow puberty are the same:

• there is not enough free space in the pen;
• no communication with a young boar;
• the pig got sick;
• nutrition is not adequate;
• there is less than 16 hours of light per day in the pigsty;
• recent move to a new paddock.

Eliminate all irritating factors, review your diet and add vitamin and mineral supplements to your food.

Obese uteruses lose sexual activity. Take your pigs out for a walk every day (weather permitting) and bring a lively boar into the sty. If the measures taken do not cause heat, you will have to call the veterinarian. The female will begin to get excited and will only allow the boar to approach her if she is completely healthy.

Some farmers advise placing the pig in a separate pen with the lights on all the time and leaving the animal without food for two days. There must be a bowl of water. But this method can cause severe stress in the sow.

Other factors

In order not to face the problem of the absence of estrus, it is necessary to provide the female with the opportunity to communicate with males from childhood. Otherwise, she will develop abnormal sexual behavior.

The same goes for wild boars. Sometimes they will not approach sows if they have not been in contact with them during puberty. Such boars can cage pigs of the same sex.

Problems with going into heat are inherited. A sow is culled if she has difficulties with the sexual cycle several times in a row. In this case, there is no point in using hormones, because the offspring can still inherit this defect.

A pig does not start walking after weaning its piglets if it has lost a lot of weight. Do not limit the queen's food intake and allow her to eat as much as she can. Even if she doesn't eat the standard portion. To stimulate females after lactation, it is better to use 2-3 boars at a time.

Mating methods

In the livestock industry, there are many different ways of mating pigs. First of all, they are divided into purebred and interbreed. The first of them is carried out with the participation of two heads of the same breed. The goal of this process is to preserve and improve the characteristics of a specific breed of pig. This mating technique allows you to maintain and at the same time increase the volume of meat products.

Pig mating methods:

1. Interbreeding. It is used in cases where the farmer wants to improve the characteristics and qualities of future livestock. This is achieved by applying the following methods in practice.
2. Absorbent mating. This type of mating involves pairing a low-productive breed with a more productive one. As a result, the breeder receives a larger number of heads, and meat productivity subsequently increases.
3. Reproductive mating. With this method, the mating process involves individuals of different breeds born in different generations. This type of mating is carried out in order to obtain a new breed that will have some desired characteristics.
4. Introductory crossing. It is carried out with one goal - to preserve and improve the general parameters of a particular type of pig.
5. Manual mating. This method of mating pigs is carried out in a large pigsty. The sow and the male are placed in a specially designated place, where the farmer sprinkles sawdust on the floor surface. Animals should be left alone so that outside noise does not distract them. After a certain period of time, the male adapts to the female and mating occurs.
6. Double cage. This technique is used more often than others. Its essence lies in the repeated mating of selected individuals, which takes place 12 hours after the initial mating. This increases the likelihood of favorable fertilization of the sow. Moreover, for this they take the same boar that participated in the first mating.
7. Artificial insemination. This technique is often used on large livestock farms. In such places, due to the large population, natural insemination is almost impossible to carry out, or it can cause certain problems. The artificial insemination process is carried out in the presence of a veterinarian. The female is implanted with semen, which before this procedure was in a special laboratory. Since biological material is subject to pre-processing and tests on it, the possibility of successful insemination is reduced to a 100% positive result. It has been proven that such a brood will have excellent health and favorable characteristics.

How to determine pregnancy

There are two ways to determine pregnancy in pigs: using special tests or by the behavior and external characteristics of the animal. The first method is the most reliable and accurate, but will cost the farmer more.

After mating with a boar, the pig is placed in a separate compartment, where good living conditions are provided. Experienced pig breeders know that a pregnant pig changes: it becomes contented, relaxed, rests a lot and eats. You can definitely be sure of pregnancy by testing or observing the female.

Behavioral features

You can determine if a pig is pregnant at home by the following signs:

• The animal is brought to the boar a couple of days after mating. If the female shows aggression, then pregnancy has occurred.
• A couple of days after mating, a pregnant pig develops a white vaginal discharge.
• During pregnancy, rapid weight gain occurs, the nipples turn purple, and the back sag.
• A pregnant sow is characterized by increased laziness and goodwill: she eats and rests a lot, grunts affectionately.
• Before farrowing, the female prepares the nest in a secluded place, chewing hay and straw.

Pregnancy can be accurately detected a month before farrowing using the following steps:

• The pig is placed on its left side.
• Massaging the abdomen, gently feel the area of ​​the abdomen between the hind legs.
• Palpate the area between the nipples, feeling for the babies.

Carrying out tests

At pig farms, the pregnancy of sows is determined using special examinations carried out by veterinarians:

• Analysis of material from the vagina. Samples of vaginal discharge are taken using medical instruments. The method is considered expensive, so it is rarely used.
• Ultrasound examination - performed with a scanner that helps establish pregnancy.
• Pregnancy test - carried out 22 days after mating. Blood is taken from the ear for a test that will confirm whether the pig is pregnant or not.

Sometimes the sow becomes covered only after mating again. If the animal becomes pregnant and is safely delivered, then mating can be repeated after six months.

When does the re-hunt begin?

It is important to know how long it takes for a pig to start walking again after the end of the previous mating. The farmer must monitor the timing of ovulation and signs of pregnancy of the animal. Sexual heat in pigs can occur cyclically. Animals feel the need to mate every 21-22 days. If for some reason the sow has not had contact with the boar, then after 2-3 weeks she will develop new symptoms of sexual desire. But even in this case, everything will depend on a certain list of factors. Some of them are the age criterion, breed and conditions in which the animal lives.

Sometimes the sow starts to estrus again even after a favorable insemination. This phenomenon is considered normal, since pigs, compared to other types of animals, have the ability to bear piglets of different ages. Therefore, during one mating, a certain number of inseminations can occur with short intervals between them. At the same time, the female feels calm; this does not appear outwardly.

By understanding how long a pig lasts, as well as knowing how to mate, it is possible to greatly improve efficiency in the livestock industry. The farmer must rely not only on the numerical values, but also on the special characteristics of each pig. In this matter, an individual approach to each animal must be observed.

At the same time, the breeder is obliged to control the level of livestock maintenance and proper nutrition. A pig suffering from certain diseases cannot participate in the fertilization process due to general malaise and impaired body functions. If you follow these mating tips, you will be able to produce healthy, large offspring every year.

Detecting a walking pig

Without boar

Signs of heat in pigs include behavioral changes and external factors. The female eats less or completely stops approaching the feeder. She constantly nervously walks around the pigsty or walking area, can turn over bowls with her hoof and squeals loudly.

The daily routine changes. In the evening the pig does not sleep for a long time, and gets up early in the morning. The genitals increase in size and turn red. Mucus flows out of them.

There is a reliable way that helps you figure out how to find out that a pig has gone on a spree. Approach the pig and press on her buttock. The sow in heat first freezes motionless, and then begins to arch and fall on her side. This behavior is called the immobility reflex.

With a boar

Signs of a pig in heat become more obvious if there is a boar in the pigsty. In its absence, it is possible to reliably determine the arousal of females only in half of the cases.

The male releases pheromones that attract the sow. Therefore, experienced pig breeders understand how to determine heat in a pig using a boar.

A boar is driven into a pigsty and taken between pens with females. A sow ready for mating freezes at the sight of a male and does not react to touching the buttock. Such a female is driven into a separate room and a boar is introduced to her. He will begin to sniff the pig, poke his nose into its side and try to approach from behind.

If the sow begins to squeal, does not allow mounting and runs away, it is too early to mate. The animal is taken to a common pen and checked again the next day.

Immobile sows are ready for mating. They are marked and taken to an individual pen for mating.

But a boar is able to stimulate heat in a female for about 20 minutes. Therefore, bring him only to prepared pigs: well-fed and rested after eating.

It is easier to determine readiness for mating if all the pigs are walking in the pigsty at the same time. The presence of pregnant queens can complicate heat detection.

Veterinary stores sell a boar-scented spray with a synthetic pheromone. It helps to detect heat in pigs. The drug is sprayed in front of the animal’s face for several minutes. If the queen stands still and does not react, she is ready to mount.

How many days does it take for the pig to walk again?

The pig's readiness for mating appears cyclically at regular intervals. If after mating the animal does not become pregnant, then over the next 21-22 days signs of heat will again appear. But it is worth noting that this time period is also inaccurate 100% of the time. Depending on the age, breed, constitution and characteristics of keeping pigs, this period lasts 14-24 days.

In some cases, the female, even after successful insemination, will again go into heat. This is explained by the fact that pigs, by their nature, are capable of bearing piglets of different ages. As a result, after the first insemination, a second one may occur, and the interval between farrowings in this situation is minimal.

The interval between farrowings can be minimal

When the pig starts to walk

If a well-fed pig is born for the first time, its birth may be unpredictable and with complications. For stable offspring, it is necessary to select pigs that have already given the farmer healthy offspring. How to understand that the selected boar is suitable for breeding? A correctly chosen piglet will allow you to understand whether the pig is ready to go for a walk or not. The sow's hunt does not last long, and during this time it is necessary to have time to do it with a suitable male. It is best to have representatives of one breed: it is very easy to spoil the genetics of the offspring, but then treating diseases in pigs is a costly and unpleasant matter for the farmer.
