How many days will it take for a pig to get the flu? What kind of medicine do you use?

1. The incidence of swine flu is high, the incubation period is 2-7 days, and the course of disease is about 1 week. In the early stage of the disease, the sick pig suddenly has a fever, lethargy, loss of appetite or abstinence, often lying together, unwilling to move, dyspnea, intense cough and mucus from the eyes and nose. If the disease is not treated in time, it is easy to be complicated with bronchitis, pneumonia and pleurisy, which increases the fatality rate of pigs.

two。 The incubation period is very short, from a few hours to a few days, with an average of 4 days at the time of natural onset. At the initial stage of the disease, the body temperature of diseased pigs suddenly rose to 40.3 to 41.5 ℃, anorexia or loss of appetite, extreme weakness and even collapse, often lying on the ground. Shortness of breath, abdominal breathing, paroxysmal cough. Mucus flows from the eyes and nose, and nasal secretions are sometimes bloody. Sick pigs lie together, difficult to move, touch muscle stiffness, pain, diaphragm spasm, respiratory setbacks, commonly known as hiccups. If there is a secondary infection, the disease is aggravated, resulting in fibrinous hemorrhagic pneumonia or enteritis. Sows are infected during pregnancy, and piglets are seriously ill 2-5 days after delivery, and some die during lactation and before and after weaning.

How to prevent and cure swine flu?

Influenza (also known as swine influenza) is an acute and infectious respiratory disease caused by influenza A virus. It is characterized by sudden onset, cough, dyspnea, fever and rapid recovery. It usually breaks out among pigs and is highly contagious and can cause death. It has a high incidence in autumn and winter, but it can spread throughout the year.

1. Epidemic characteristics: pigs of all ages, genders and breeds are susceptible to this virus. The epidemic of the disease has obvious seasonality, and the weather is changeable in late autumn, early spring and cold winter. The disease spreads rapidly and is often endemic or pandemic. The incidence of the disease is high, and the mortality rate is (4%-10%). Sick pigs and infected pigs were the source of infection of swine influenza, and pigs were infected for 6 to 8 weeks after recovery from the disease.

two。 Clinical symptoms: the incubation period of the disease is very short, from a few hours to a few days, with an average of 4 days at the time of natural onset. At the initial stage of the disease, the body temperature of diseased pigs suddenly rose to 40.3 ℃ ~ 41.5 ℃, anorexia or loss of appetite, extreme weakness and even collapse, often lying on the ground. Shortness of breath, abdominal breathing, paroxysmal cough. Mucus flows from the eyes and nose, and nasal secretions are sometimes bloody. Sick pigs lie together, difficult to move, touch muscle stiffness, pain, diaphragm spasm, respiratory setbacks, commonly known as hiccups. If there is a secondary infection, the disease is aggravated, resulting in fibrinous hemorrhagic pneumonia or enteritis. Sows are infected during pregnancy, and piglets are seriously ill 2-5 days after delivery, and some die during lactation and before and after weaning.

3. Prevention and treatment measures: there is no effective vaccine and special treatment for the disease. it is important to take good care of the pig house and keep it clean, dry, warm and free from thieves. Provide an adequate supply of clean drinking water and limit the supply of feed in the first few days of recovery. Timely detection and isolation of diseased pigs, strengthen disinfection. At first, the diseased pigs should be mixed with amoxicillin + amantadine + Qingwen Baidu powder. If the symptoms are mainly in the respiratory tract, florfenicol + azithromycin + amantadine + multidimensional mixture can be used. Some pigs do not eat food, can be intramuscular injection of drugs to help it open, another antipyretic drug analgin can be used. If the body temperature is too high and persists, dexamethasone sodium phosphate 5mg / 12mg or compound aminopyrine 5~10mL intramuscular injection can be used. Recommended formula of traditional Chinese medicine: honeysuckle, forsythia, Radix Astragali, Bupleurum, Fructus Arctii, tangerine peel and licorice each with 10 to 16 grams of water, once a day for 3 days. Or use 6 grams of Bupleurum, 18 grams of Fangfeng, tangerine peel, peppermint, 12 grams of Penny Ben, Poria peel, Fructus Aurantii, 15 grams of chrysanthemum, 16 grams of perilla, ginger for water diversion.
