When a suckling or grown up pig coughs, he shows signs of lethargy and a painful condition. The structure and functional work of the pig organism is extremely similar to that of humans, therefore animals suffer from diseases that manifest themselves in a similar way. A strong and regular cough can cause various infections, parasites, as well as foreign objects in the respiratory system.
Cold Sore Animals
The causes of coughing in pigs can be completely different and the breeder needs to learn how to identify them in a timely manner in order to protect and treat pigs.
Experienced veterinarians, even by external signs, can determine what provokes the manifestation of cough, recommending to change the conditions of detention and feeding. They are able to offer medications for the treatment of viral infections or the destruction of parasites that have settled in the body of an animal.
The main causes of coughing in piglets are divided into:
Sometimes foreign bodies can get into the respiratory tract of a pig, but in this case, the process of coughing is quite fast.
When keeping piglets in cold and poorly ventilated rooms with a high level of humidity, many animals can catch colds. They cough, behave excessively excited, or, conversely, become apathetic.
The color of the ears changes from pink to gray, which is the first sign of a cold.
Treatment with medications quickly eliminates the causes of coughing, and the pig recovers.
Animals may also have a cough when there is a lack of vitamins and nutrients in the body, which are not eaten with poor quality feeds, or when they are overfed. Therefore, the conditions of the pig should be fully consistent with sanitary and hygienic standards, and feeding of pigs should be carried out in accordance with all the recommendations of specialists.
Cough due to stomach problems
Piglets taken away from sows and transferred to a standard diet can suffer from gastroenteritis. Their ears and piglet become blue, babies suffer from constipation and diarrhea, become lethargic, eat poorly and do not gain weight. Occasional cough appears.
The best way to eliminate gastric diseases of babies is washing the digestive tract with a saline concentration of 0.9%. It is recommended to give a laxative - sodium sulfate, and 1 teaspoon of vegetable oil, which is added to the feed before it is fed to the piglets.
An excellent remedy is a decoction of onions or garlic. The heads are filled with boiling water in the ratio of 1 to 10, the tincture is given to the piglets one tablespoon twice a day.
For the treatment of diarrhea, chloramphenicol is used, and when dehydrating a piglet, it is necessary to inject saline. To strengthen the immune system is required to add glucose, which is introduced in the amount of 15-20 ml twice a day. In some cases, the use of various antibiotics, which are prescribed by a veterinarian. For anesthesia applied 1.5% novocaine solution. Be sure to add vitamins to the feed.
Self-treatment of colds and other diseases can lead to negative consequences, therefore, it is required to use the advice of a veterinarian who will prescribe a course of treatment suitable for each diseased pig.
Infectious pneumonia and tuberculosis
Pigs can get pneumonia. In the presence of this disease, they have difficulty breathing, wheezing and dry cough, conjunctivitis appear, the body temperature rises and crusts appear on the skin. Piglets become lethargic and depressed, move little, eat poorly and consume large amounts of water.
Similar symptoms have infectious tuberculosis of pigs, which is a much more dangerous disease.
When the first signs of animal pathology appear, it is recommended to isolate from the main herd and invite a representative of the veterinary service, who will take a smear of the mucous membrane for laboratory analysis.
After identifying the causative agent of infection, the veterinarian determines what to do to destroy it. Treatment of tuberculosis is considered to be costly and meaningless, so it is recommended to discard sick pigs.
Pneumonia is treated with a combination of drugs that include antibiotics such as Oxytetracycline, Tilan and Spiramycin. For disinfection of the herd, spraying of Norsulfazole and Etazol aerosols is permissible.
Misuse of antibiotics, with the help of which you decide to treat coughing pigs, can lead to negative consequences. The pig's body quickly adapts, and further treatment with them can yield absolutely no results.
Dangerous disease ascariasis
In some cases, the cause of coughing in piglets can be infection with a variety of parasites that affect the gastrointestinal tract, circulatory and respiratory systems, as well as the brain, liver, heart and other organs.
The most dangerous parasites are roundworms that cause the disease, called ascariasis.
For ascaris, the body of the pig is the main host in which the parasite grows, develops and multiplies. The adult form of the helminth lives in the intestines, where it absorbs nutrients and multiplies.
The length of the females is 20-35 cm, and the males - 25 cm.
The female lays up to two hundred thousand eggs per day, which do not have devices for independent movement. They, along with fecal masses leave the body and accumulate in aviaries. Given that in the digestive tract of a diseased pig there are tens or even hundreds of parasites, the number of eggs in the waste can be tens of millions.
Infection of new animals with the larval stage of biohelminth occurs through the entry of ascaris eggs into the mouth, and from it into the stomach and intestines of the pig.
Parasitic lung larvae
In the intestine of the carrier, the parasite's eggs lose their shell, turning into larvae. The latter pierce the intestinal wall, penetrating into the blood vessels and lymphatic fluid. Together with the flow of blood, they are spread throughout the body. The larvae are localized in the liver, heart, pulmonary artery and the lungs themselves.
The development of the larval form of roundworm mainly occurs in the bronchi and alveoli of the lungs. During growth and development, the larva releases toxic substances. They cause poisoning of the body, which uses the capabilities of its immune system to neutralize them.
In the lungs mucus accumulates, which interferes with proper breathing. Piglets periodically cough up mucus containing ascarid larvae. Part of the worms re-enters the pig's mouth, causing it to re-infect the parasite.
Adult roundworms live in the body of a pig for up to 5-7 months, and re-distribution with coughing mucus prolongs the course of the disease, which is very dangerous for pregnant pigs and dairy pigs.
Isolation and Mandatory Antibiotic Treatment
The pulmonary form of helminthiasis in pigs, accompanied by wheezing, coughing, difficulty or accelerated breathing, as well as vomiting and lack of appetite, requires the immediate treatment of piglets.
When symptoms of ascariasis appear, sick animals should be immediately transferred to an isolated room. Their enclosures are required to be cleaned from waste, food and water residues that may be contaminated with helminth eggs.
Disinfection is required, for which a 5% solution of caustic potassium or soda, a 0.15% solution of "Blanidas 300", and a 3% solution of iodine chloride are used.
The veterinarian will promptly determine why the piglets cough, establish the presence in the body of pigs of larvae or adult ascarids. He will prescribe a course of treatment for sick animals and possible carriers of the infection. Most often, these are fenbendazole-based drugs that have no side effects and do not cause allergic and embryotoxic reactions that affect the health of the offspring developing in the body of sows.
This may be "Fenzol", "Fenzol-K", "Brovadazole", "Albendazole", "Brovalsen".
Prevention of helminthiasis and the observance of sanitation
Ascarids are especially dangerous for sows and the offspring they produce. Women in labor are advised to perform obligatory deworming for 1 month before farrowing. This allows you to protect against a new generation of parasites.
If the piglets born into the world are infected with worms, it is often not possible to save their lives.
The first course of prophylactic treatment for helminths is prescribed to pigs for 33-40 days after their birth, and repeated deworming is carried out at the age of 50-55 days. If young pigs show the first signs of coughing, it is acceptable to conduct an additional course of treatment for ascaris and other worms.
Remember that the appearance of cough in piglets can be a sign of serious health problems, which can only be eliminated as a result of drug treatment and the use of antibiotic drugs.
But often enough, the culprits of common colds, coughing and sneezing in pigs are the livestock breeders themselves, who contain their herd in insufficiently heated rooms with a high level of humidity. The reason for the spread of various infections can be non-compliance with sanitary and hygienic standards, as well as the use of feed that does not have the appropriate quality and safety certificates.
