Winter: frequent occurrence of pig disease and prevention and control measures

-and answer questions from readers in Shijiazhuang and Hengshui. Recently, readers in Shijiazhuang, Hengshui and other places reported that the temperature gradually dropped after winter, and pig diseases began to increase, seriously affecting the efficiency of farming. Therefore, combined with the occurrence characteristics of pig diseases in winter, we suggest that we should do a good job in the prevention and treatment of pig respiratory diseases and pig digestive system diseases. -Editor 1. Respiratory diseases, which mainly represent respiratory syndrome, are the focus of the pig industry in winter. The main features of these diseases are cough, asthma, dyspnea and increased nasal juice. Prevention focuses on reducing cold stimulation, and treatment focuses on getting to the root of the problem rather than relieving asthma. 1. Cold is easy to cause cold, such as coughing, stuffy nose, runny nose, sneezing and tears. Cold itself is not very harmful, but it is easy to cause other diseases. If it is not treated in time, it can lead to bronchitis and pneumonia. Prevention should be based on improving the microclimate of pig houses, and the main work is to strengthen warm measures to prevent the attack of thieves. Treatment, but intramuscular injection of analgesin nearly 5g 10ml or compound aminopyrine 10ml 20ml, traditional Chinese medicine can use "Jingfangbaidu Powder": 20 grams of Jing Fangfeng, 15 grams of Notopterygium, 25 grams of Bupleurum, 15 grams of Bupleurum, 15 grams of Fructus Aurantii, 20 grams of Platycodon grandiflorum, 30 grams of Poria cocos, 10 grams of Ligusticum chuanxiong, 10 grams of hay. 2. Influenza influenza is caused by influenza virus, which is similar to common cold symptoms, but it is serious, epidemic, and often occurs in a large area, with body temperature rising up to 40 ℃ ~ 42 ℃, shortness of breath, abdominal breathing, cough and mucous secretions from the eyes and nose. Prevention, can be used Guanzhong, eucalyptus, honeysuckle, Radix Isatidis, Folium Isatidis 15 grams of decoction for internal use. For treatment, valium can be used, combined with analgin and aminopyrine, penicillin and streptomycin are injected twice a day. Human and swine flu are infected with each other, we must pay attention to self-protection. 3. The pathogen of asthma in pigs is Mycoplasma pneumoniae. The clinical manifestations are dry cough, open mouth and severe wheezing, and the number of breaths can reach 100 per minute. Attenuated porcine asthma vaccine for prevention can produce good protective effect 3 days after inoculation, and the immune protection period can reach 8 months. Oxytetracycline or kanamycin can be injected intramuscularly for 5 days. The dosage of oxytetracycline is 25 mg / kg body weight and the dosage of kanamycin is 40,000 units / kg body weight. Tylosin, lincomycin, spectinomycin, doxycycline and other drugs can also be used for treatment. 4. Lung disease pig lung disease is caused by Pasteurella multocida. Although it is an old disease for many years, it is still sporadic every winter. The main manifestations are high difficulty in breathing, open mouth breathing, foam-like fluid flowing from the mouth and nose, standing of the forelimbs and landing on the buttocks like the sitting position of the dog, sometimes dry and short spastic cough, and chronic type mainly shows persistent cough. Because the main symptoms and classical swine fever, porcine anthrax, porcine asthma, infectious pleuropneumonia and other diseases have many similarities, clinical should be carefully distinguished, the focus of identification is to see whether the dog sitting posture. Prevention, can be subcutaneously or intramuscularly injected with inactivated aluminum hydroxide vaccine of porcine lung disease, each time 5 ml, 14 days after injection to produce immunity, the immune protection period is 6 months. For treatment, penicillin, gentamicin, tetracycline, sulfonamides or quinolones can be used with ideal results. Second, digestive system diseases mainly show digestive system syndrome diseases, which are very common in winter. The main manifestation of this kind of disease is dysentery, various colors, more sundries, and serious weight loss. When treating common diarrhea, we should cure both the symptoms and root causes, and infectious diarrhea should give priority to prevention. The main results are as follows: 1. The occurrence of enteritis is caused by not only primary factors such as sudden climate change, improper feeding and management, poor feed quality, but also secondary factors such as bacterial infection and drug stimulation. The main manifestations are vomiting, diarrhea, vomit mixed with blood or bile, fecal stench, feces containing blood, mucus, mucous membrane, sometimes mixed with pus, late fecal incontinence, anal relaxation. If it is not treated in time, it will die from dehydration, salt loss and acidosis. The comprehensive treatment measures are as follows: ① cleans the intestines, removes toxins and protects the intestinal mucosa. First take 500ml of laxatives such as paraffin oil or vegetable oil, then 1000 ml of 0.1% potassium permanganate solution, and add 100g of medicinal carbon at the same time; ② fermentation to reduce inflammation. Take 20 grams of fish stone fat, combined with 15 grams of sulfonamidine, ③ fluid infusion to strengthen the heart and relieve acidosis. Intravenous injection of 500-1000 ml of sugar saline and 250 ml of 5% sodium bicarbonate. (to be continued) 2. Bacterial diarrhea is an important season for raising piglets in winter, but piglets often die of bacillary dysentery. Bacillary dysentery includes dysentery, colibacillosis, clostridium enteritis, piglet paratyphoid and other diseases. In daily management, comprehensive identification and prevention should be made according to epidemiology and clinical symptoms. The first preventive measure is to control temperature, strengthen management and pay attention to prevent all kinds of stress reactions. 1-3-day-old piglets developed diarrhea, mostly red dysentery, that is, piglet clostridium enteritis. The pathogen of red dysentery is Clostridium welchii type C. the disease is characterized by bloody stool mixed with small bubbles. To prevent, aluminum hydroxide vaccine of piglet red dysentery can be used. Sows were injected with 5 × 10 ml intramuscularly one month and half a month before delivery. Piglets about 1 week old after birth developed diarrhea, mostly yellow dysentery. Piglets at the age of 10 to 30 days after birth developed diarrhea, mostly white dysentery. Yellow dysentery and white dysentery are colibacillosis. The main manifestation of yellow dysentery is yellow or yellow-white paste dung, white dysentery is milky white, gray-white or yellowish green paste thin feces. The harm of yellow dysentery and white dysentery is relatively serious, and prevention must be done in advance. K88-LTB bivalent genetic engineering vaccine can be used to inject 5 milliliters of sows at 30-45 days and 15-20 days before delivery. Rukangsheng is mainly used for drug prophylaxis. One tablet (0.5 g) can be taken every morning and evening after birth for 2 days, and then every other week for 6 weeks. Biological agents such as promoting bacterial growth and regulating dysentery can also be used for prevention and treatment. According to the experiment, suckling piglets with white dysentery can be given aspirin once in the morning and evening, each time 8-10 tablets (0.5 grams per tablet), generally fed for 2 days. Diarrhea occurred in 7-12-week-old pigs, which is suspected to be Treponema pallidum dysentery. Treponema pallidum dysentery is a disease caused by the interaction between Treponema pallidum and specific anaerobes in the intestinal tract. Generally, yellow or gray soft stools are discharged first, followed by watery feces, which are mixed with blood, mucus and mucous membrane. So far, there is no vaccine that can be vaccinated, but antimicrobials can be used for prevention, such as adding 50ppm to the feed. Dysentery Jing, lincomycin and tylosin can be used for treatment. Piglets at the age of 2 ~ 4 months after birth have diarrhea, but they are suspected to have paratyphoid fever. Paratyphoid fever of piglets is caused by salmonella and is often mixed with classical swine fever and porcine asthma. The acute type begins with constipation, followed by dysentery and foul-smelling feces; the chronic type is the most common, with initial constipation followed by persistent or intermittent diarrhea, yellowish or yellowish green stench and thin stools mixed with blood, necrotic tissue or cellulose fragments. Prevention, can be subcutaneously or intramuscularly injected with attenuated paratyphoid virus freeze-dried vaccine of piglets, each time 1 ml, after weaning injection can produce strong immune protection. Treatment, you can choose oxytetracycline, neomycin, trimethoprim, sulfadiazine, furazolidone and so on. 3. Viral diarrhea in the cold winter season, if dysentery occurs in pigs of all ages, but the symptoms of adult pigs are mild and the disease of young pigs is serious, it should be suspected that they have viral diarrhea, such as rotavirus disease, epidemic diarrhea and transmissible gastroenteritis. The above three kinds of virus diseases are mainly characterized by vomiting, defecation of various colors or watery stool, and the harm is serious, but there is no specific drug treatment. To prevent porcine epidemic diarrhea, attenuated or inactivated vaccine against porcine epidemic diarrhea should be vaccinated in advance, and 1 ml of attenuated porcine transmissible gastroenteritis vaccine should be injected intramuscularly and intranasally 45 and 15 days before delivery in sows. There is no vaccine for rotavirus disease. after diseased pigs are found, they should be isolated as soon as possible. 5%-10% glucose saline is injected intravenously and 3%-5% sodium bicarbonate is added. Piglets should stop breastfeeding and prepare glucose glycine solution for piglets to drink. The formula is: glucose 43.2 g, sodium chloride 9.2 g, glycine 6.6 g, citric acid 0.52 g, sodium citrate 0.13 g, anhydrous sodium phosphate 4.35 g, dissolved in 2 kg water. -- good article, support-- reply "zhmdchinaren Thank you for your support."
