What vaccine should be given for pig cough? What s going on with the pig cough

It may or may not be able to fight.

Autumn and autumn are high and cool, the climate is dry, and the temperature difference between day and night is large, which is easy to cause pig coughing and wheezing. Once the pig farm is infected with this disease, it is difficult to completely eliminate, and it can also make the infected pigs stunted, reduce the feed conversion rate, and cause serious economic losses. So, what measures should we take to prevent the occurrence of pig cough and asthma?

1. Improve air quality. Pig coughing and asthma can only spray out the secretions containing pathogens through coughing, panting, and sneezing, forming droplets, and being infected through the respiratory tract. Ventilation should be increased to ensure air circulation, reduce the concentration of pathogens in the pig house, reduce the concentration of ammonia in the pig house, dust and a large number of pathogenic microorganisms, and control the spread of diseases.

2. Immunization and vaccination. Vaccination is an important measure to control the spread of the disease. For pig farms that often have pig cough and asthma, vaccine immunization should be carried out, and piglets should be immunized once at the age of 7-15 days using attenuated freeze-dried vaccine for pig asthma; Gilts are vaccinated once before breeding; Or use Ma Xing Shi Gan San + Timicosin premix for seven days.

3. Strengthen feeding management. Reducing the density of stocking, as an increase in stocking density means that the probability of infectious diseases is also increasing, so it is necessary to reduce the stocking density. Do a good job of disinfection, and investigate the epidemic limit on the pig house 1-2 times; Dirty water and feces with pathogenic microorganisms need to be treated harmlessly; Reasonable diet, feeding nutritionally balanced feed, so as to give less to the diligent addition, to keep the pig house dry.

1. Porcine tracheitis:The main symptoms are cough, runny nose, and tracheal sensitivity. Cough, which starts as a dry cough and then becomes wet, often occurs in the morning.

Runny nasal discharge, initially serous, later becomes mucous or even purulent. The trachea is palpated, and its sensitivity is increased.

2. Ascariasis:This is a common parasitic disease caused by Ascaris suis parasitic in the small intestine of pigs. When infected with a small number of eggs, the eggs multiply into larvae, and migrate in the body can occur Ascariasis pneumonia, causing cough symptoms, when roundworms parasitize a large number of intestinal blockages, abdominal pain in sick pigs, and even intestinal rupture and death.

3. Swine asthma:This is a contact, chronic respiratory infectious disease of pigs caused by Mycoplasma pneumoniae, also known as endemic pneumonia or mycoplasma pneumonia, the main symptoms are cough, wheezing and dyspnea, and local breed pigs are the most susceptible, with a higher incidence and lower mortality rate.

Precautions for pig raising.

Pig breeding needs to pay attention to the feeding of feed, the cleaning of the pigsty, etc. It is also important to prevent viruses. When raising pigs in ordinary times, you can feed some rough feed to promote gastrointestinal peristalsis and nutrient absorption.

When there are pregnant pigs in the pen, it is necessary to improve the feeding appropriately, choose a feed that is easier to digest, and add some organic matter to it. In the swine fever period, it is necessary to do a good job of cleaning the feces, strengthen ventilation, reduce the reproduction of germs, and disinfect in advance.

Pig cough is closely related to the air quality of the pig house, so to solve the problem of pig cough, we must start from the source, ventilation and disinfection, and keep the air clean. For sick pigs with severe cough, it is necessary to use drugs such as asthma according to the situation**.

If the pig cough problem occurs, the following methods can be used:

1. Improve the air environment: strengthen ventilation, keep the pig house dry, sprinkle water frequently, and reduce dust.

2. Reduce feeding density: Reducing density can effectively control the spread of cough.

3. Mixing feeding: Chinese herbal medicine and antibiotics (Banqing granules + immunity housekeeper) can be used for mixing feeding.

The physiological structure of pigs has many similarities with humans, and some of them can be cultivated in medicine for transplantation of pig organs for later use in humans**.

After pigs are infected by the respiratory tract, they will also have a bacterial discharge reaction, and coughing is an important manifestation of bacterial discharge.

If the pig has a cough, it may be an infection such as pneumonia or tracheitis, which needs to be carried out with anti-inflammatory drugs and cough and phlegm drugs**.

If you are not active, excessive respiratory infections will cause infection and death, which will indirectly affect economic benefits, so I hope you will actively give pigs ** to avoid infection and death.

Bless you with wealth and wealth.

The first thing to consider is what is causing the cough. General cough is now more caused by mycoplasma, and the effect is better with mycoplasma (Tai Miao). If it is caused by infectious pleuropneumonia, parahemophilia, nasal atrophy, etc., the effect of florfenicol + doxycycline is better.

There are also some pig farms that have used ciprofloxacin, enrofloxacin and other quinolones with good results. Roxithromycin is effective in the initial use, but it is prone to drug resistance. Azithromycin and roxithromycin are the same kind of drugs, and they are also new drugs, and the effect is better, but ** is too high.

Another important consideration is the presence of parasites, such as lung filaria, which can also cause coughing, in which case the precursor worm is called. There are many causes of cough and diarrhea in pigs, and it is necessary to look at other symptoms to draw conclusions, otherwise it will be misdiagnosed. Porcine Lung Disease Porcine lung disease is an acute infectious disease caused by the bacterium Pasteurella multocida.

It is also called swine pasteurosis. The main clinical characteristics and symptoms are acute hemorrhagic sepsis, pharyngitis and pneumonia, commonly known as "throat lock madness" or "swollen neck plague" Clinical characteristics acute type: some did not see any symptoms of sick pigs, ate normally at night, and found dead in the pen the next morning, which is the most acute.

Common acute type of pigs show body temperature rise as high as 41-42, loss of appetite, bedridden or irritable, dyspnea, elongated head and neck breathing, throat redness, fever, hardness, some extended back to the chest, as a dog sitting wheezing sound, mouth and nose foam. Visible mucosal cyanosis with erythema on the ventral, auricular bases, and medial extremities**. Some also present with acute pleurisy symptoms such as cough and pain on chest palpation; Some have constipation at the beginning, diarrhea later, often due to suffocation, the course of the disease varies from a few days, and the immortal becomes chronic.

The chronic type is mainly manifested by symptoms of chronic pneumonia and chronic gastroenteritis, and if not timely**, it will mostly die of failure after 2 weeks.

Prevention and control methods: preventive injections are carried out according to the immunization program.

Isolate sick pigs after the onset of the disease, and use antibiotics and sulfonamides in a timely manner**. In the epidemic area, the use of ragomycin 44 premix, in addition to the prevention and treatment of bacterial diseases such as pig lung disease and porcine dysentery, has the effect of promoting growth, increasing weight gain, and improving feed meat exchange rate for healthy pigs.

In non-epidemic areas, do a good job in pig farm hygiene, disinfection, and feeding management, which can avoid the disease caused by multocidal pasteur infection. Answer: It's simple, swine flu!

Pigs will not die if they cough and get the swine fever vaccine. If infected with the swine fever virus, the swine fever antibody in the pig will kill the swine fever virus, in short, the swine fever vaccine is also a swine fever virus, but it is a weakened swine fever virus. If you have swine fever, you already have the swine fever virus in your body.

Swine fever vaccine note:

The vaccine mostly uses swine fever rabbit attenuated vaccines, with cell seedlings and tissue seedlings, and produces immunity 3 to 5 days after vaccination. Usually breeding boars are vaccinated twice a year, with 4 servings per pig each time; In order to exclude the interference of maternal antibodies, suckling piglets were injected with 4 copies at the age of 21 and 24 days, and the same dose was given at the age of 55 and 60 days.

Pig cough and swine fever vaccine, improper epidemic prevention, may lead to death.

First of all, the cough should be cured, and then the vaccine epidemic prevention, the swine fever vaccine must be in good health of the pig, and the cough and sick pig vaccine will be more serious.

The new generation of quinolones is the best drug for this disease. The freeze-dried seedlings of segregated asthma disease produced in China can be used for healthy piglets at the age of 20-25 days, and the immunization rate can reach more than 80%. Pig farms must breed their own breeding herds to strictly prevent the invasion of pathogens from this disease.

The disease does not vary in species, age or sex, and can occur throughout the year, but is more common in cold, rainy, humid or sudden changes in climate. Poor feed quality, crowded, damp and poorly ventilated barns are the main causes. The mortality rate is not high when infected alone, but once the herd is introduced, it is difficult to completely eliminate it without strict measures.

Veterinary medication, 10% florfenicol powder.

Compound sulfahexamethazine sodium powder mixed with feed, or mixed with water for drinking, for three to five days ---

The landlord said that the pig cough may refer to the mixed infection of the respiratory system, which has always been the first problem of the pig farm, first of all, to improve the small environment of the pig house, pay attention to the heat preservation in winter while strengthening ventilation, to prevent over-cold or over-hot stress, and secondly, in the winter and spring pay attention to the addition of medicine to the medicine health care, if you prepare long-term mixing, it is recommended to use traditional Chinese medicine preparations (licorice, andrographis, banlan root and other compound preparations), if you are ready for a short time for health care, it is recommended to use Western medicine, Macrolide antibiotics (such as tylosin, tilmicosin, azithromycin, etc.), lincomycin + spectinomycin, tetracyclines can be added to chloramphenicol, such as doxycycline + florfenicol, and quinolones can also be added, such as ciprofloxacin, enrofloxacin, etc. General medication 5-7 days. Caution incense can also be added to the feed to prevent respiratory diseases.

(i) Overview.

Pig cough is pig asthma, also known as pig asthma, pig mycoplasma pneumonia or mycoplasma porcine pneumonia, and is called endemic pneumonia abroad.

The pathogen is Mycoplasma swine pneumoniae, which was once translated as Mycoplasma. The pathogen is mainly found in the respiratory tract, lungs, and hilar lymph nodes of pigs.

Porcine asthma is a chronic respiratory infectious disease, characterized by cough and wheezing, high morbidity, low mortality, affecting the growth and development of pigs, and at the same time prone to secondary infection with many diseases, bringing significant losses to pig production.

The incidence of disease was not age, breed, gender, seasonality, and the morbidity and mortality of suckling piglets and young pigs were higher, followed by late pregnancy and lactating sows.

Cold, wet, rainy, improper feeding management, poor hygienic conditions, etc. can induce the disease or aggravate the disease. Sick pigs have a long time to carry the bacteria, some for about 1 year.

2) Clinical symptoms.

intermittent cough and wheezing, runny nose, visible mucosal cyanosis; There was no significant change in appetite, growth was stunted.

The body temperature is generally normal, but if a secondary infection occurs, the body temperature rises, and the condition is complicated.

iii) Pathology.

Significant lung lesions, enlarged, hydropulmonary and pneumopulmonary tracts; The anterior inferior edge of each lobe of the lung has confluent bronchopneumonia lesions with obvious boundaries.

From "pork-like changes" to "pancreatic changes" or "shrimp meat-like changes" (reddish-gray lesions can be seen in the early stage, and the cut surface is fine and honey-like like pork, commonly known as the flesh changes of the lungs, and in the later stage, it is light purple, dark red, gray-yellow, and the toughness increases, commonly known as "pancreatic changes").

Pericarditis, pleurisy, pulmonary and pleural adhesions may be seen after secondary infection.

4) Prevention and control.

Chinese lung spirit is also called ceftiofur sodium for injection; Calculated as ceftiofur, intramuscular injection: one dose, per 1kg body weight, 3-5mg in cattle and pigs, once a day, for three days.

Immunization: inactivated piglets with asthma, piglets 1 5 days old, head; Seed retention is exempted from 3 to 4 months of age; Breeding males and sows 2 times a year, 5ml times.

1. Piglet cough is related to the decline of sow antigen.

Piglets are not very resistant to the outside world after birth, and to a large extent, they resist the infection of respiratory diseases by inhaling antibodies to sow colostrum, so immunizing sows is an effective way to effectively prevent cough in piglets. For example, asthmo can be vaccinated 2-4 weeks before farrowing.

2. Use antibiotics in advance to prevent cough in piglets.

The use of antimicrobials prevents concurrent and secondary bacterial infections after viral infections. It is best to use antibiotics to identify bacteria and do antimicrobial susceptibility testing, and generally amoxicillin, lincomycin and other piglets have a certain effect on bacterial cough.

3. Pay attention to feeding management and improve the feeding environment.

Especially in autumn, the temperature difference between day and night is large, so it is necessary to ensure the insulation of piglets, the cleanliness of the pig house, the prevention and control of thief wind invasion, and the good ventilation in the pig house (ventilation can be carried out when the temperature is high at noon) These measures can reduce the chance of coughing piglets.

4. Observe whether cough occurs in the first parity of sows.

If the sow has a cough in the first litter, many of them may be due to the low maternal antibodies of the sow, and it may cause long-term cough in the case of low antibody levels, so in this case, all in and all out or isolation, weaning as soon as possible and other methods can be taken to ensure the health of the piglets.

For pigs with the first onset of disease, florfenicol powder + doxycycline hydrochloride + ephedra houttuynia powder can be used**.

The general cold can also cause pigs to cough, fever, eat less runny nose and other characteristics.

If it is a cold, in addition to strengthening the feeding management, it can be cured with some antipyretic and analgesic drugs, and the commonly used drugs are.

5-10 ml of compound aminopyrine, or 3-5 ml of 30% analgin, plus 5-10 ml of Bupleurum injection, 80-2.4 million units of penicillin intramuscularly, twice a day, for 2 days.

In addition, pigs suffering from wheezing disease can also cough, wheezing, and difficulty breathing, which is a chronic infectious disease caused by mycoplasma.

**Method: 1Mix oxytetracycline raw powder into the feed every day for 2 months; 2.Mycoplasma, take 9 grams of this product dissolved in 50 kg of water for 10 days of continuous drinking, or add 25 grams of this product per 10 kg of feed, and 2-3 grams of it will be effective after use.

With the arrival of winter and spring, the temperature changes greatly, and the occurrence of pig respiratory diseases will occur at this time, causing different degrees of economic losses to the national pig industry. To this end, we combine years of clinical experience to launch the active symptoms of porcine respiratory diseases in winter and spring to control the secondary infection of pathogenic microorganisms. The top priority to save pigs is to reduce fever, promote food, improve body circulation, alleviate acidosis, and use drugs with a wide antibacterial spectrum and strong antibacterial properties to control secondary infections and reduce complications.
