1. This disease is a kind of acute contact infectious disease caused by swine fever virus. Among them, the incidence of piglets and small shelf pigs is high, and the mortality rate is high. The pig died suddenly and his body temperature was above 41°C. Sustained heat retention, like drilling, grass, conjunctival flushing, eyelid, limping, initial constipation, post-diarrhea, feces with blood. Red spots on the skin, finger pressure does not fade. Prevention: 1 to strengthen the feeding tube, regular use of caustic soda water or kill the disinfection of pens, strictly immune prevention. 2 Intramuscular injections of 5 to 6 doses of swine fever vaccine to the affected pigs resulted in a cure rate of 90%-100%. 3 gypsum, Shichangpu, Patrinia 150 grams each, 100 grams of pine needles, honeysuckle rattan, Digupi each 80 grams, Shuijianbi, a daily dose, once every 3-5 days. 2. Porcine pulmonary epidemic (commonly known as laryngeal wind or porcine hemorrhagic septicemia) Pigs eat normally at night and die in the pens in the morning, and do not see symptoms. The temperature of chronic swine pneumonia increased to 41-42°C. Breathing difficulties, canine sitting posture, red spots in ear and abdomen, rapid swelling of neck throat, thermal pain in palpation, white foam in mouth and nose, and weight loss in diarrhea. Prevention: 1 strengthen feeding and management, feed should be appropriate. Each year, the pigs' aluminum hydroxide formaldehyde formaldehyde vaccine was injected 1-2 times, 5 ml each time. 2 pigs can be used penicillin per kilogram body weight 40,000 units, aminopyrine 15 ml intramuscular injection, 2 times a day. 3 intramuscular or intravenous injection of 20% sulfadiazine sodium 10-40 ml. 4 Sinfanfolium (9 14) Injection, 0.6 g for 5 month old pigs, 0.7-1 g for 6-12 months old pigs, 1-1.5 g for pigs 12 months old, and 5% solution with normal saline Intravenous injection, the effect is quite significant. 5 Daqingye, gypsum, mountain bean root, rhubarb, Houttuynia, Astragalus, Phellodendron each 25 grams, Shuijianbi, used in conjunction with 2-3 agents. 3, swine erysipelas caused by brontoalosis bronchial 3-12 months old pigs prone. Body temperature rises above 42°C, continues to retreat, and features erythematous red patches of varying sizes on the limbs. Prevention: 1 regular injection of bacterin, commonly used 10% -20% lime milk disinfection barn, pigs should be isolated feeding. 2 Penicillin was 4-5 million units per kilogram of body weight, and 10 to 20 ml of amniotic fluid was intramuscularly injected. 350 kg of the following pigs with special effects 5 ml first, 50 g more than 1,000 with 10 ml, intramuscular injection, 4 times a day. 4 Daqingye 100 grams, raw gypsum, Fritillaria, Banlangen each 50 grams, crushed as the end, boiling water conditioning temperature irrigation service. 4. The body temperature of swine pneumonia patients rises to 41°C, the cough is runny, and the breathing is difficult. Prevention and control: 1 Strengthen feeding and management, keep the pig house dry and warm, and feed easily digestible feed. 2 Use penicillin at a rate of 40,000 units per kilogram of body weight, 20,000 units of streptomycin, 20 ml of 50% glucose saline, and 0.5 g of vitamin C, mixed intravenously, twice daily for 2 days. 3 oxytetracycline daily 25-50 mg per kilogram of body weight, use 5-7 days. 4Kanamycin was intramuscularly administered at 2 to 4 million units per kilogram of body weight once daily for 5 days. 5 Astragalus membranaceus, pollen, melon barley, winter flowers, gypsum each 50 grams, honeysuckle 30 grams, Daqingye, rhubarb 50 grams, 25 grams of licorice Shuijianbi. 5, sudden onset of swine flu, body temperature up to 40 °C, loss of appetite, cough, runny nose, conjunctival flushing, easy repeated. Prevention: 1 Strengthen feeding management, keep the house clean and dry, and regularly disinfect with 20% caustic soda water. 2 Analgin or aminopyrine 10-20 ml intramuscularly, 2 times a day for 3-5 days. 3 viral spirit 10-20 ml, gentamicin 5-10 ml intramuscularly, 2 times a day. 4 penicillin 2-3 million per kilogram of body weight, 10 ml of procaine solution dissolved intramuscularly, once daily.
