General information

What are infectious diseases in pigs?


Diseases in piglets, like any other farm animals, can be mild or serious. Some diseases of piglets are considered incurable and often lead to the death of animals. Other diseases of pigs with proper treatment go away in a few days.

In any case, all the diseases of piglets can be classified into two large groups:

The pathologies of both these varieties are capable of causing serious damage to farms.

Contagious diseases

Ailments of this particular group occur in piglets are often very difficult and lead to a reduction in the herd. The most common infectious diseases of pigs are:

A very dangerous infectious disease of such farm animals is, of course, also African swine fever.

Non-contagious diseases

Such illnesses usually do not proceed as hard as infectious. However, due to such diseases, pigs often lose significantly in productivity, and sometimes die. Non-communicable diseases can be diagnosed in animals of absolutely any breed. These diseases affect piglets Landrace, Lithuanian, Duroc, etc.

Most often, pigs are diagnosed with the following pathologies of this group:

Ascariasis: economic damage

This chronic disease is caused in piglets with round worms Ascaris suum, parasitizing in the small intestine. The main reason for the development of such a disease in pigs is the failure of sanitary standards in the barn. Piglets are infected with ascaris mainly through feed and water.

Economic damage to the farm, no matter how little piglets are bred in it - Durok breeds, Estonian bacon, Urzhum and others - ascariasis can cause significant. Piglets die from this disease rarely. But at the same time, consuming a large amount of feed, infected pigs are not gaining weight well. In addition, the meat of patients with ascariasis pigs are forbidden to eat. Infected by such worms, unfortunately, can including people.

Symptoms of Ascariasis

Leakage of this disease in piglets can be both acute and chronic. Symptoms of ascariasis in both these cases are the same. The only thing with the chronic form of signs of infection with Ascaris suum will be less pronounced.

It is possible to suspect ascariasis in pigs on the farm in the presence of such symptoms:

allergic reaction of unknown origin,

increased body temperature

A sign of chronic ascariasis is also a serious loss of weight of the animal.

Preventive measures

Infected ascariasis in the household most often piglets under the age of 6 months. To carry out all sorts of activities to prevent the development of such a disease, of course, necessary for pigs of all ages. However, the young in this case should be given maximum attention.

Measures for the prevention of ascariasis in farms usually take the following:

perform deworming of pigs from other farms,

twice a year they do preventive de-worming of the herd,

deworming uterus for 30 days before farrowing.

When carrying out prophylactic deworming, the treatment of the pigsty with insecticides is also performed at the same time.

Treatment of the disease

Ascariasis that has already developed in pigs in farms is usually fought with the use of modern anti-parasitic drugs. To the piglets of the Duroc, Kalininsky, Breitovsky, Vietnamese breeds, etc., with this disease they usually give

"Piperazin salt". This drug is given to pigs twice a day with food. The course of treatment is 1 day.

"Fenbendazol." This medicine is also added to piglets in feed. A dosage of 10 mg / kg is used. The course of treatment in this case is 1 day.

Such drugs are used for deworming at once of the whole herd. It is absolutely useless to give antiparasitic drugs to only one animal in this case.

Trichinosis: source of infection

This disease also belongs to the group of helminth infections. It is called a special type of nematode - Trichinella spiralis - and is dangerous also for humans. Pigs can become infected with such worms through feed, from sick piglets, etc.

There is an infection of landrace piglets, large white, North Caucasian, etc. trichinosis under the same conditions as ascariasis. This disease can manifest itself in two forms - muscular and intestinal.

What to do?

It is possible to prevent the development of this disease in pigs by observing sanitary standards on the farm, quarantining newly purchased pigs, thermal processing of feed, etc. Trichinosis is a disease from which treatment, unfortunately, has not been developed. But it is still believed that Tiabendazole, Mebendazole, Albendazole can help the piglets from this disease.

Causes of dysentery

This disease is a type of contagious and usually occurs in pigs in a very acute form. In another way, this disease is called piggy typhus, black diarrhea, etc.

The causative agent of dysentery is the bacterium Treponema hyodysenteriae. The main reason for the development of this disease becomes non-compliance with sanitary standards in the pig houses. Also, dysentery infection contributes to poor feeding, which often results in weakening of the immunity of animals.

Symptoms of dysentery

This infectious disease is considered to be one of the most dangerous for pigs. Mortality of suckling and newborn piglets from dysentery, for example, is 100%. The temperature of pigs infected with Treponema hyodysenteriae, as with many other infectious diseases, does not rise. Animals with such ailment and appetite do not lose.

The main sign by which this disease can be identified is loose stools in piglets. Diarrhea in pigs usually occurs 1-3 days after ingestion of the causative agent of dysentery. The feces of sick animals first become watery, and then become brown and fetid.

In addition, the symptoms of dysentery in pigs are:

lack of coordination of movements.

Prevention of dysentery

Measures to prevent the development of this disease, since it causes farms to be truly enormous damage, should, of course, be mandatory. Preventive measures aimed at reducing the risk of dysentery and diarrhea in piglets, usually include the following:

quarantine piglets brought from other farms for 30 days,

preventive disinfection of farms,

treatment of pig skin with an alkaline solution of formaldehyde.

The danger of dysentery is, among other things, the fact that pigs with this disease practically do not develop immunity. Very often this disease in piglets is repeated. Not developed and vaccines for this disease.

African swine fever: causes

This terrible disease can be tolerated (mechanically) by rodents, cats, dogs, birds. Of course, pigs can get infected from sick pigs. They are carriers of this disease and insects - mites, gadflies, fleas, etc.

Ailment is, unfortunately, very dangerous. For example, in the Novgorod region, African swine fever only in the summer of 2018 killed about 37 thousand animals, causing enormous harm to the farms. This virus has spread in Russia since 2007.

Symptoms of African Plague

Very often, this disease, unfortunately, is asymptomatic. The animal just suddenly perishes. Thus manifests fulminant form of the disease. In acute plague in piglets, the following symptoms are noticeable:

sudden rise in temperature

white offensive discharge from the ears, eyes and nose,

paralysis of the hind limbs,

When the disease becomes chronic, pigs have the following symptoms:

slight cough and fever,

sores and sores on the skin

What to do to prevent development

Of course, so that African swine fever in the Novgorod region, Moscow, Novosibirsk, Yekaterinburg and any other throughout Russia does not cause damage to the economy, farms should be taken against it all sorts of preventive measures.

The treatment of this disease today, unfortunately, has not been developed. The farmer can only try to prevent its development in piglets. Prevention measures against African swine fever include:

purchasing animals with only a veterinary certificate,

regular disinfection of pigsties.

How to identify: signs

In the lightning form of this disease, piglets die quickly and without symptoms. The next morning the hosts simply discover the corpse of the animal. But most often the edema in piglets is still acute. In this case, it can be determined by the following symptoms:

a sharp increase in body temperature

inadequate response to loud noises (irritation, seizures).

Ultimately, asphyxia develops in the pig, as a result of which he dies.

In chronic form, edema develops mainly in adult pigs. It manifests itself in this case, lack of appetite, general depression.

Treatment of Edema

For the prevention of the spread of disease all piglets with visible symptoms immediately after their detection are transferred to a separate room. At the same time, infected animals are prescribed a diet for 10-12 hours. At the same time, the pigs are given a laxative.

In order to reduce the intoxication in case of edema, piglets are offered sulfate magnesia. At the same time, they constantly make sure that animals always have enough water in their drinking troughs.

Swine erysipelas

This disease in piglets is caused by the bacterium Erisipelotrix insidiosis. Its main carriers are infected pigs, birds and rodents. Flies that mechanically spread this bacterium can also infect pigs. Usually pigs get sick with erysipelas at the age of 3-12 months. At the same time this disease develops most often in summer, spring or autumn. In winter, pig pigs do not get sick. This ailment does not develop in newborn piglets, who are immunized from their mother with milk.

The causes of infection in this case, as in most others, are non-compliance with sanitary standards, poor animal welfare conditions, an unbalanced diet. Very often, the causes of an outbreak are:

fever in the pigsty,

abrupt change in feeding mode.

Swine erysipelas: symptoms and treatment

The acute form of this disease in pigs is characterized by the following symptoms:

a sudden rise in temperature

rejection of feed.

Pigs with sharp mug refuse to move, burrow into the litter, breathe heavily. In this case, their skin becomes bluish in color. In the next stage, the disease becomes subacute. At the same time on the body of the pig appear initially colorless, and then dark swelling. When transitioning to the chronic form, the piglets develop skin necrosis in the erysipelas.

Measures to save animals from this disease must, of course, immediately after its symptoms are detected. The treatment of swine erysipelas and its prevention involves, above all, the creation of good housing conditions for the pigs. Also against this disease in pig farms are periodically vaccinated. It uses a special serum in combination with penicillin antibiotics.

Inoculations are given to piglets from erysipelas on farms at the age of 2 months. Vaccine is administered to animals twice with an interval of 14 days. Repeat the procedure in the next 6 months.

Sick pigs in farms are treated with antibiotics, as well as give them antipyretic drugs and drugs that promote the removal of toxins from the body.


This disease in pigs is often diagnosed simultaneously with erysipelas. Pasteurellosis is characterized in piglets primarily by infecting the blood with pathogenic microorganisms, as well as inflammation of the intestine and upper respiratory tract. The causative agent of this disease is the stick Pasteurella multicida.

The reasons for the development of this disease are usually high humidity in the pigsty, hypothermia, crowding. Also contribute to the outbreak of the epidemic in the herd may be defective feeding.

What are the symptoms

Pasteurellosis is a fairly dangerous, requiring immediate treatment for the disease of pigs. And the symptoms in any case, of course, every farmer should know. To determine this disease in pigs can be on the following grounds:

a sharp rise in temperature

general depression.

When the disease becomes chronic, the pigs develop the following symptoms:

eczema of the skin.

Sick pigs in the chronic stage, among other things, begin to lose weight rapidly.

Treatment and prevention of pasteurellosis

In order to prevent the development of this disease in pigs, vaccines are periodically carried out on farms. Also regularly perform disinfection of premises. Treatment of pasteurellosis is quite effective when using antibiotics. Pigs on the farm can be given, for example, "Tetracycline", "Levomycetin", "Terramycin", etc.

Gastroenteritis in pigs: causes

In this disease, the piglets inflame the stomach and intestines. At the same time, pathological processes are observed at once in all three layers of the walls of these organs.

This non-communicable disease develops in piglets, usually due to disturbances in nursing technology. From what the piglets are fed Vietnamese, Lithuanian whites, Durokes, etc., their health and developmental characteristics depend directly. Pigs can get gastroenteritis, for example, if they are offered low-quality, moldy, stale food. Also, this disease is often diagnosed in animals due to poisonous herbs and all sorts of irritating drugs. In small piglets, this disease often develops due to the abrupt transition to milk-free feeding.

Sometimes this problem in pigs occurs due to stressful situations. Gastroenteritis in piglets can be diagnosed, for example, after transportation, hypothermia, overheating, etc.

The main symptoms of the disease

A sign of the development of gastroenteritis in piglets is primarily a violation of the gastrointestinal tract and intestinal function. The main symptoms of this disease are:

When diagnosing gastroenteritis in pigs in the first place, of course, the cause of its occurrence should be eliminated. That is, low-quality feed should be removed from pig feeders, excluding the possibility of them eating poisonous grass, etc.

In fact, for the treatment of sick piglets, they are kept on a starvation diet for 12-24 hours. Next, animals are transferred to a special light diet. At the same time give pigs hay flour, meadow grass, talkers of oatmeal, carrots.

Of the drugs in gastroenteritis, the piglets are well helped by saline laxatives, solutions of sodium chloride with glucose and gastric juice. In severe cases, the glucose-saline solution may also be administered intravenously or intraperitoneally to animals.

Peptic ulcer

In this disease in pigs there is a defective defeat of the mucous and underlying tissues of the stomach. The causes of peptic ulcer in piglets can be:

long-term feeding with dry or overly chopped feed,

some types of helminthiasis.

In some cases, the pig ulcer may be perforated.


At the moment, according to statistics, on farms, gastric ulcer develops in 5% of sows and about 60% of piglets in rearing. That is, this disease can be considered very common.

Unfortunately, it is usually very difficult to determine a peptic ulcer in pigs. The symptoms of this affliction are not specific. Usually, if there is such a problem, the piglet has:

Often the sick pig begins to vomit with blood. Blood is also detected in the feces of an unhealthy animal. In case of a perforated ulcer in the pig, inflammation of the peritoneum can also be observed.

How to carry out the treatment

Pigs with peptic ulcer disease, of course, are supposed to be given only the highest quality feed. To alleviate the condition of such an animal by offering him raw eggs, jelly, oat broths, broths. Also give pigs with peptic ulcer:

In addition to everything else, piglets with iron and multivitamins are given weekly to sick piglets.

For the prevention and treatment of peptic ulcer disease, it is of great importance what Vietnamese, Duroc, large whites and any other piglets are fed. Diet for sick pigs is developed in such a way that they get enough protein, fiber and vitamin E in sufficient quantities. Also ensure that the piglet menu does not include too many feeds containing poorly digestible fat. Very suitable for such animals, among other things, a ration based on whey and milk.

Kinds of infectious diseases of pigs

Infectious diseases are caused by various pathogens - viruses, bacteria, pathogenic fungi. They enter the body of the animal through the digestive tract, microdamages on the skin, sexually. The main characteristics of infectious diseases are:

  1. They are able to quickly be transmitted to healthy individuals.
  2. The course of disease usually has several stages - hidden, precursors, acute, stage of recovery.
  3. After recovery, immunity to the pathogen is formed, thanks to antibodies that are produced in the blood of the recovered animal.

Most often pigs are infected with such infectious diseases:

  • Viral gastroenteritis.
  • Erysipelas
  • Circovirus infection.
  • Paratyphoid.
  • Aujeszky's disease.
  • Edema disease of piglets.
  • Dysentery.
  • Parvovirus infection.
  • Leptospirosis in pigs.

To have an idea about the pathogens of these ailments, their manifestations and prognosis, consider each item in detail.

Viral gastroenteritis

Transmissible gastroenteritis causes a coronavirus. Getting into the digestive tract of pigs, it provokes the occurrence of inflammation of the gastric mucosa.

Infection of animals occurs predominantly during watering.

Infection of animals occurs predominantly by the alimentary route at the time of watering, eating the food contaminated with microorganisms. Carriers of the virus - sick pigs, birds, rodents, domestic animals.

Reference. Animals that have had viral gastroenteritis continue to secrete the virus with feces and urine for 2-3 months.

The disease is most dangerous for suckling piglets, they die 3-5 days after infection. Consider the symptoms of viral gastroenteritis:

  1. Loss of appetite.
  2. Depressed. Temperature increase (usually short term).
  3. Vomiting.
  4. Diarrhea (fecal fluid, greenish, their discharge occurs involuntarily).
  5. Dehydration, manifested by sticking of the eyes, dry mucous membranes.
  6. In lactating sows, milk production stops.

Treatment of viral gastroenteritis begins immediately. Sick pigs are immediately separated into an insulator, feeding is stopped for a day. Inside give furatsilin or furazonal - antimicrobial agents. Broad-spectrum antibiotics are administered intramuscularly. Since diseased individuals lose a lot of fluid, it is necessary to restore water and electrolyte balance. Pigs otpaivat salted water. With frequent vomiting, solutions that compensate for the lack of fluid and mineral salts are administered intravenously.

Food is offered only in liquid form. It is advisable to use sorbents to relieve symptoms of intoxication. When animals begin to recover, it is recommended to give them probiotics to normalize microflora.

A bacterium called erisipelotrix insidiosis causes the face. It enters the body through the respiratory system, through the skin or with food. If the disease is acute, it is characterized by the development of septicemia, endocarditis, skin necrosis and polyarthritis.

Outbreaks of erysipelas occur predominantly in the warm season. Sources of infection are sick animals, contaminated feed, water. Most often, piglets are ill in the age of about one year. The course of the disease may be different, it depends on the degree of virulence of the pathogen, the age of the animal, the conditions of its housing, the immune status.

Reference. Fulminant and acute course of the disease almost always ends in the death of pigs.

Symptoms of erysipelas in the acute form of the disease:

  1. The sharp rise in temperature to 40.5-41 degrees.
  2. Refusal to eat.
  3. Oppression.
  4. Chills.
  5. Thirst.
  6. Difficulty breathing.
  7. Cyanosis of the skin in the neck, peritoneum.
  8. The appearance of characteristic pink spots on the sides and back of the animal, which soon darken, become purple.
  9. Necrosis of the skin.
  10. Intestinal atony.

If the erysipelas is subacute, conjunctivitis may develop, a rash on the body. Bulges in the shape of triangles appear in the sides and back of the diseased individual, rhombuses, which eventually merge.

Reference. The appearance of characteristic spots on the body of a pig is a good sign. Usually after this the animal becomes easier. Gradually, the rash passes, and the condition stabilizes.

For the chronic course of the disease is characterized by impaired cardiac activity and the development of arthritis.

The treatment of erysipelas is carried out with anti-whey serum and antibacterial agents. It is administered subcutaneously. The dosage is calculated based on the weight of the animal (approximately 1.5 ml per kilogram of weight). Penicillin antibiotics are administered intramuscularly:

  1. Streptomycin.
  2. Oxytetracycline.
  3. Erythromycin.

To relieve symptoms, medications that stimulate the heart, intestines and nervous system will be used.

Attention! If a healthy specimen is suspected of being infected with erysipelas, they are immediately vaccinated, patients are kept separately, in an isolation ward, premises require disinfection with caustic soda or bleach solution.

Circovirus infection

This infectious disease affects piglets recently weaned. The causative agent is a DNA virus that multiplies in the lymphoid tissue. The source of infection is sick individuals. The spread of infection contributes to the crowded housing of animals, poor ventilation, often the cause is early vaccination of pigs (up to two months of age). The virus is transmitted mainly by airborne droplets, sometimes from sows.

Symptoms of circovirus infection:

  1. Piglets sleep a lot, weakened.
  2. Lagging behind, exhausted.
  3. The sucking reflex is poorly developed.
  4. The skin becomes yellowish.
  5. Ears pale or even bluish.
  6. Diarrhea.
  7. There is a tremor.
  8. Violation of coordination of movements.
  9. On the skin manifestations of dermatitis - a rash, irregular spots.
  10. Sometimes conjunctivitis develops.

An effective treatment for circovirus is still under development. For the purposes of prevention, vaccination of sows and piglets is recommended, however, it should not be performed immediately after weaning from the mother when the babies are under stress.

Circovirus infection of piglets

Salmonella bacteria cause this disease. They enter the body of animals in the alimentary way - with food or water. The causative agent of paratyphoid fever is extremely resistant to external factors, so this disease is very difficult to treat. The disease affects piglets under the age of six months and causes changes in the circulatory and nervous systems and is accompanied by severe intoxication of the body. The paratyphoid proceeds mainly in a chronic form, but in animals with low immunity, including small piglets, the course of the disease is acute.

Symptoms of paratyphoid pigs:

  1. A sharp rise in temperature to 41.5 degrees or more.
  2. Loss of appetite.
  3. The animal is depressed, lies buried in the litter.
  4. The bristles are ruffled.
  5. The skin tone changes from pink to gray.
  6. Diarrhea.
  7. Eczema.
  8. Fecal malodorous, gray-green color.
  9. Closer to the final stage of the disease, the skin on the ears, neck gets a bluish tint.

Reference. With the acute form of paratyphoid, there are practically no chances to survive in piglets. Death occurs within a few days.

In chronic course, the symptoms are smoother, there is diarrhea, which is often replaced by constipation, the animal loses weight.

Antibiotics (chloramphenicol, tetracycline) and nitrofurans are used for the treatment of paratyphoid fever, as well as special serum containing antibodies to the pathogen. Vaccination helps prevent outbreaks. It is carried out to suckling piglets who have reached the age of 20 days, twice with an interval of 8 days.

Aujeszky's disease

This infectious disease is caused by a DNA herpesvirus. Piglets up to the age of two months are most at risk of infection. Infection occurs as a nutritional route, and through the respiratory system, mucous membranes and damage to the skin. The source of the virus is sick animals or virus carriers (recovered individuals that continue to excrete pathogens with urine, feces, mucus for several weeks after recovery). Mortality is quite high - among the piglets only 4-5% of individuals survive. Aujeszky's disease is accompanied by disorders of the nervous system, as the virus penetrates into the brain of animals and multiplies there.

Symptoms of Aujeszky's disease in piglets (acute):

  1. Fever.
  2. Excitement, great anxiety.
  3. Hard breath.
  4. Excessive discharge of frothy saliva.
  5. Sneezing
  6. Pigs take unnatural poses for them, make swimming movements, lying on their side.
  7. Convulsive syndrome.
  8. Paralysis of the limbs, larynx.

In adults, the disease is much easier, animals recover in a few days. Among the symptoms can be identified - loss of appetite, depression, cough (the disease is complicated by pneumonia).

There is no effective treatment regimen. Practice has shown that the use of immunoglobulins does not give the expected result. To prevent the development of pneumonia, sick animals are advised to inject antibiotics and give vitamins. After recovery, the adults are virus carriers.

Edema disease of piglets

The causative agent of edematous disease is E. coli. After entering the pig, it affects the digestive organs and the central nervous system. Toxins secreted by pathogenic bacteria cause vascular dystonia and hemostasis. As a result, the tissues do not receive enough oxygen, and fluid accumulates in them. Edemas are formed not only under the skin, but also in the internal organs and brain. Edema disease affects mainly pigs of weaning age.

E. coli is the causative agent of edematous disease.

  1. Temperature increase to 42 degrees.
  2. Anxiety.
  3. The sensitivity of the skin is increased (when touched, the pigs squeal).
  4. Cramps in the muscles of the limbs, neck.
  5. In the future, there is swelling of the eyelids, frontal part, nose, ears.
  6. Refusal of food.
  7. Diarrhea or vomiting.
  8. Signs of heart failure - the pulse quickens, but the blows are weak.
  9. The skin of the ears, piglet, peritoneum is blue.
  10. Shortness of breath develops.
  11. Shortly before death, seizures and muscle paralysis may begin.

For the treatment of edematous disease using a broad spectrum antibacterial drugs, as well as nitrofurans. Antihistamines are administered intramuscularly. Piglets are given hexamine to reduce vascular permeability. A specific treatment regimen and drugs for edematous disease does not yet exist.


Dysentery is an infectious disease that is caused by spirochaete, an anaerobic bacterium. Outbreaks are most often recorded in winter and spring, when the immune system of pigs is somewhat weakened. Infection enters the body by alimentary. Multiplying in the intestines, it causes disruption of the digestive tract, diarrhea, intoxication of the body. The disease affects swine of any age, but the young are especially at risk of infection. Mortality among monthly piglets reaches 100%.

  1. Severe diarrhea (fecal mass is watery gray-green with blood).
  2. Dehydration (eyes sink, mucous membranes dry).
  3. Thirst.
  4. Weakness, wobbly gait.
  5. Pallor of the skin.
  6. Sometimes vomiting.
  7. Exhaustion.

The treatment is carried out with preparations for which the spirochete is sensitive. For example, Osarsol. Along with this, furazolidone is also used, since other pathogenic microflora predominate in dysentery in the intestine.

Parvovirus infection

This disease is inherent only in pigs, it is caused by a pathogen belonging to the genus Parvovirus. Clinical manifestations of the disease are observed only in females. These include:

  1. Abortion
  2. Infertility.
  3. Stillbirth
  4. Mummification of fruits.

Parvovirus infection occurs through contact with sick animals or virus carriers, as well as through the placenta from sows. Treatment for this disease is not developed. As a prevention, use a vaccine containing inactivated viruses.

Leptospirosis in pigs

This disease is caused by a mobile spirochete Leptospira. Microorganisms are represented by many species. The pathogen enters the body of pigs through the digestive tract, skin and sexually. For some time, spirochetes are in the blood, and after the production of antibodies, they are established in the kidneys of the animal. Leptospirosis leads to the birth of dead fetuses, early abortion abortions or the birth of non-viable piglets.

Clinical signs of infection are similar to the flu:

  1. The animal is depressed.
  2. The temperature is elevated.
  3. No appetite.
  4. Diarrhea or constipation may occur.
  5. Conjunctivitis.
  6. In pregnant pigs, abortions occur within a month after infection.

For the treatment of leptospirosis, streptomycin is used, as well as some derivatives of tetracycline and penicillin. Antibiotics are administered intramuscularly. As a preventive measure, it is recommended to carry out vaccination against leptospirosis, after which the body’s resistance to the pathogen persists for 6–12 months.

Infectious diseases can cause very large losses to the farm. Particularly at risk of young. That is why it is advisable to try to prevent them from spreading on the farm. It is necessary to conduct a routine vaccination of livestock on time. Such a measure will help avoid mass infection with dangerous infections.

The onset of the disease is manifested by fever and the appearance of a rash on the patch and the mucous membrane of the mouth. The stage of the initial vesicles is accompanied by hyperthermia - 42 ° C. Vesicles are opened, exudate expires, yellowish crusts form. Secondary bubbles occur in the interdigital space. See lameness. Panarcium develops, hoofed horn disappears. Record the birth of dead fruits in sows.

Sick piglets are transferred to a semi-liquid diet, antibiotic therapy is used to relieve symptoms. Livestock with clinical signs are slaughtered, the meat is sent for processing for the manufacture of sausages. The room is disinfected.

Arthropod Diseases

The greatest damage to the health of pigs from parasites of this group is delivered by subcutaneous mites. They damage the skin mechanically, as well as cause intoxication with metabolic waste, manifested by an allergic itch. Scabies develop, caused mainly by mites from the genus Sarcoptes. The resulting skin defects are exposed to microflora infection, which is widespread. Alopecia occurs, pigs lose weight. Treatment consists of treatment with external agents with antimicrobial, acaricidal, anti-inflammatory, and analgesic properties. If necessary, use injection drugs that destroy arthropods, and incidentally - parasitic worms.

Alimentary pathologies

Characterized by indigestion - vomiting, diarrhea, constipation, intestinal swelling, dehydration. The treatment is carried out mainly by symptomatic means. Most often, diseases of the alimentary canal cause poisoning due to the following reasons:

  • Spoiled food. The use of fermented food waste, feed, infected pathological fungi.
  • Errors in feeding. Use increased amounts of salt. Feeding the feed, for pigs not intended, salted fish, BVMK.
  • Drug poisoning. Occur in overdose of drugs used for deworming or treating another disease. Additional symptoms - nervous phenomena, signs of heart, liver or kidney failure, anemia. Sometimes the cause of poisoning becomes personal intolerance to the components of the medicine. With excessive clogging, despite the correct dosage, intoxication caused by the death of a large number of parasites is observed.
  • Poisoning poisonous plants. Occur when feeding green mass or grain waste, heavily littered with weed seeds.

Respiratory diseases

The most well-known disease in pigs of non-infectious etiology, affecting the respiratory organs with characteristic symptoms and specific treatment, is considered to be a disease of lung piglets. Pathology is caused by the use of dry food of extremely finely ground or powdered consistency. Small particles are inhaled, enter the pigs lungs, irritate them. Microflora, trapped in the respiratory system with feed, causes inflammation.

Developed bronchopneumonia. Symptomatic treatment, with the use of antimicrobial, expectorant, fortifying agents.

Piglet diseases

Piglet diseases affect them mainly in the first weeks of life. They cause enormous damage to pig breeding due to high lethality. The most common pathologies are listed below:

  • Swine flu.
  • Viral pneumonia.
  • Edema disease.
  • Hypoglycemia.
  • Anemia.
  • Rickets.
  • Dyspepsia.
  • Furunculosis.

Swine flu

Piglets up to 1 month of age mostly get sick. According to the antigenic properties and symptoms of the disease, the swine flu resembles a human one. Pathology has a pronounced seasonality, which is why it occurs in the fall with a sharp cooling. Often the cause of the disease becomes stress after weaning - the sow is removed, and the piglets are left alone. The source of infection are recovered virus carriers. Swine flu is characterized by the following symptoms:

  • Hyperthermia.
  • Depressed.
  • Lack of appetite.
  • Cold symptoms are sneezing, coughing, red eyes.
  • The limbs, tail and ears become bluish.
  • Piglets prefer to lie.

The cunning of the disease consists in complications that arise after a temporary improvement in the condition. Arthritis, sinusitis or meningitis, pneumonia develops. Mortality in complications reaches 60%. Symptomatic treatment. Prevention of the disease consists in observing the zoohygienic standards of piglet keeping. A person can become infected through contact with them.

Viral pneumonia

Заболевание характеризуется перманентным течением. It occurs mainly in suckers and weaners. Manifests dry cough. Appetite is preserved, but weight gains stop. Most often, recovery occurs without treatment. Such pigs must be rejected. They are virus carriers, grow poorly. Treatment of the disease is aimed at suppressing secondary microflora. Tetracyclines are effective, for example, Nitox, which is administered once.

Edema disease

Enterotoxemia occurs as a result of post-release stress and is caused by Escherichia coli, normally present in the alimentary tract of a pig. It takes time for the digestive enzymes to go from lactose milk to carbohydrate starch. In pursuit of weight gain, pig breeders feed the piglets with a protein-rich feed mixture that is not fully digested. Excess nitrogen serves as food for pathogens.

The little pig does not eat anything, it lies, its eyelids swell, its muzzle, inflammation spreads to the brain. Observe staggering gait, convulsions, paralysis, death.

Prevention of the disease consists of bringing the prefabricated dietary feed intended for weaned piglets into compliance with the norms of the housing system.


The disease develops in the first 1.5–2 days of life of the pigs. They are lethargic, poorly suck, there is hypothermia, pallor and dry skin, blue eyes. The lack of measures leads to the death of piglets. The cause of the disease is colostrum deficiency in sows. How to treat hypoglycemia?
