Autumn is a high-risk stage of swine lung disease. Do you have pig farmers ready for defense? The pig suddenly died under unforeseen circumstances. Many pig farmers have no way to deal with this situation, the most serious of which is the most serious. That's the pig lung disease we want to talk about today!
Introduction to swine lung disease:
Swine plague is an acute infectious disease caused by Pasteurella multocida (Pulmonary bacillus), commonly known as "lock throat" and "swollen neck". It is pathogenic to a variety of animals and humans, and is most susceptible to pigs. The death of the pig lung disease is an instant death, the fastest death. It was normal before death, and it was dead in the blink of an eye. There is no incubation period and any pathological changes.
Causes of the incidence of swine lung disease:
Porcine pneumonia is an infectious disease caused by Pasteurella. The bacteria are often found in the respiratory tract of healthy pigs. When the climate is abrupt, overcrowded, long-distance transportation, poor management, etc., the disease is caused by the decreased resistance of pigs. Diseased, dead pigs have a large number of Pasteurella, which is the main source of infection. Healthy pigs are exposed to contaminated feed, utensils, etc.
Clinical symptoms of swine plague:
The body temperature suddenly rises to about 41 ° C, do not eat, breathing difficulties, throat swelling, hard and hot. Sick pigs sometimes sit in a dog position. There are erythema on the skin of the ear, ventral side and limbs. Sick pigs die in one day, and some die in 2-3 days.
How to prevent and treat pig lung disease:
1. The best antibiotics are chloramphenicol and gentamicin, followed by tetracycline and ampicillin, but Pasteurella can produce drug resistance. If there is no obvious effect after applying certain antibiotics, it should be replaced immediately.
Dosage: chloramphenicol 10-30 mg per kilogram body weight, gentamicin 1-2 mg per kilogram body weight, ampicillin 4-11 mg per kilogram body weight, 4-15 mg per kilogram body weight of tetracycline, twice daily Intramuscular injection until the body temperature drops and the appetite is restored. Qing Zeng'an injection is 0.1 ml per kilogram of body weight, intramuscularly, twice a day, with good results.
2, commonly used sulfa drugs are sulfadiazine 10% sulfadiazine sodium solution, 20 ml of piglets, 40 ml of large pigs, intramuscular injection once a day, or 0.07 grams per kilogram of weight, twice daily intramuscular injection. 10% sulfamethazine sodium was injected at 0.07 g per kg of body weight and intramuscularly twice daily.
