I. Respiratory diseases
Diseases that mainly manifest respiratory syndrome are the focus of winter pig industry. The main features of these diseases are: cough, wheezing, difficulty breathing, and increased nasal fluid. Prevention focuses on reducing cold stimulation. Treatment focuses on treating the disease rather than on asthma.
1, cold
Cold attacks can easily cause a cold, manifested as cough, stuffy nose, runny nose, sneezing, tears. The cold itself is not very harmful, but it is easy to cause other diseases. If the treatment is not timely, it can lead to bronchitis and pneumonia.
Prevention should focus on improving the microclimate of pig houses. The main work is to strengthen the measures for keeping warm and prevent the thieves from invading.
Treatment, can be intramuscular injection of Analgein 5 ~ 10 ml or compound aminopyrine 10 ~ 20 ml, Chinese medicine can be used "Jing anti seizures powder": Nepeta 20 grams, 20 grams of wind, not live 15 grams, 25 grams of Bupleurum, 15 grams of Qianhu, 15 grams of Citrus aurantium, 20 grams of Campanulaceae, 30 grams of Chinese wolfberry, 10 grams of Chuanxiong, and 10 grams of hay.
2. Flu
Influenza is caused by the flu virus and is similar to the common flu but it has serious symptoms. It has a strong epidemic. It often has a large area. The body temperature rises to 40°C to 42°C. Breathing is rapid. Abdominal breathing, cough, eyes and nose are present. Outflow of mucus secretions.
For prevention, 15 grams of Jianshui can be used orally for each of Guanzhong, loquat leaves, honeysuckle, Banlangen, and Daqingye.
The treatment can use Ammonium Chloride, with metamizole, aminopyrine, twice daily injection of penicillin, streptomycin. People and swine flu infect each other and must take care of their own protection.
3, asthma
The pathogen of porcine asthma is mycoplasma pneumoniae. The clinical manifestations are dry cough with low head, gasping mouth, wheezing, and respiratory rate of up to 100 per minute. To prevent the use of attenuated porcine asthma bacterins, 3 days after inoculation can produce good protection, immune protection period of up to 8 months. The treatment can be intramuscular injection of oxytetracycline or kanamycin for 5 to 7 days. The oxytetracycline dose is 25 to 50 mg/kg body weight and the kanamycin dosage is 40,000 units/kg body weight. Tylosin, lincomycin, spectinomycin, doxycycline and other drugs can also be used.
4, lung disease
Pneumoconiosis caused by Pasteurella pneumoniae, although it is an old disease for many years, but there are sporadic winter every year. The main performance is high breathing difficulty, showing mouth breathing, outflow of foam-like fluid in the nose and mouth, standing on the forelegs, butting on the ground like a dog, sometimes dry and short sputum cough, and chronic type of persistent cough. Because the main symptoms have many similarities with swine fever, swine anthrax, swine asthma, infectious pleuropneumonia and other diseases, clinically careful differences should be made. The key point of differentiation is whether or not to express dog sitting posture.
Prevention, subcutaneous or intramuscular injection of inactivated aluminium hydroxide seedlings in pigs, 5 ml per head, 14 days after injection, immunity, and 6 months of immune protection.
Treatment can use penicillin, gentamycin, tetracycline, sulfonamides, or quinolones, with good results.
Second, digestive diseases
Diseases that mainly represent digestive system syndromes are very common in winter. The main manifestations of these diseases are diarrhea, diversified colors, and more miscellaneous items, and severe weight loss. Treatment of common diarrhea should address both the symptoms and the symptoms, and infectious diarrhea should be prevention-based.
1, enteritis
The occurrence of enteritis has both primary factors such as sudden changes in climate, improper feeding and management, and poor feed quality, as well as secondary factors such as bacterial infections and drug stimulation, and it is a very common clinical disease. The main performance is vomiting, diarrhea, vomit mixed with blood or bile, excrement odor, feces contain blood, mucus, mucosal tissue, sometimes mixed with pus, late bowel movement incontinence, anal relaxation. If treatment is not done in time, it will be fatal due to dehydration, salt loss, and acidosis.
Comprehensive treatment measures are: 1 clean up the intestinal tract, eliminate toxins, protect the intestinal mucosa. First, pour the paraffin oil or vegetable oil and other laxatives 500 ml, after the oral administration of 0.1% potassium permanganate solution 1000 ml, while adding medicinal carbon 100 grams; 2 making yeast anti-inflammatory. Filled with 20 grams of ichthyol, with the use of 15 to 20 grams of sulfonamides; 3 rehydration cardiac, relieve acidosis. Intravenous injection of 500 to 1000 ml of saline, 250 ml of 5% sodium bicarbonate was added. (to be continued)
2, bacterial diarrhea
Winter is an important season for rearing piglets, but piglets often die of bacterial dysentery. Bacterial dysentery includes dysentery, E. coli disease, Clostridium enteritis, piglet paratyphoid and many other diseases. Daily management should be based on comprehensive identification of epidemiological and clinical symptoms of prevention and treatment, the first preventive measure is to control the temperature, strengthen management, pay attention to prevent all kinds of stress response.
After 1 to 3 days of age, piglets developed diarrhoea, mostly erythrasma, which is the case of cholera enteritis. The pathogen of red snapper is Clostridium perfringens type C. The disease is characterized by blood excretion and mixed with small bubbles. For prevention, piglets can be used to produce aluminium hydroxide bacterin, and sows are injected with 5 to 10 ml of muscle intramuscularly 1 month before and 2 weeks before delivery.
About 1 week after birth, piglets developed diarrhea, mostly jaundice. After 10 to 30 days of age, piglets develop diarrhea, mostly white. Jaundice and white peony are all E. coli disease. The main performance of Astragalus is to pull yellow or yellow-white paste-like dilute feces, and white bastard is to pull milk white, grayish white or light yellow-green paste-like dilute feces. The damage of Astragalus membranaceus and Angelica dahurica is severe, and prevention must be done well in advance. K88-LTB dual-gene engineering vaccines can be used to inject the sows 1 to 5 days before and 15 to 20 days before delivery. Ml. Drug use is mainly used for breast health. It is possible to take 1 tablet (0.5 g) orally every morning and evening after the piglet is born. Use it once every 2 weeks and once every other week for 6 weeks. It is also possible to use biological agents such as bacteriophage, dystoxin, etc. for prevention and treatment. According to experiments, white piglets occur in suckling piglets, and aspirin can be fed to sows, once or twice a day, 8 to 10 tablets (0.5 grams each). Generally, they are fed for 2 days.
Diarrhea occurs in 7-12 weeks old piglets after birth, and Treponema dysentery can be suspected. Treponema dysentery is a disease caused by the interaction between Treponema pallidum and specific anaerobic bacteria in the intestine. Usually, yellow or gray soft stools are discharged first, followed by drainage-like feces, and feces contains blood, mucus, and mucous membranes. So far there are no bacterins that can be inoculated, but antibiotics can be used for prevention, such as adding 50ppm of schizophyllan or wolfberry in the feed, the results are good. Treatment can be used nettle mold, lincomycin, tylosin.
Diarrhea occurs in piglets aged 2 to 4 months after birth and paratyphoid in piglets can be suspected. Piglet paratyphoid caused by Salmonella, often mixed with swine fever and swine gasp disease, acute type constipation, post diarrhea, row odor faeces; chronic type is the most common, early constipation, followed by persistent or intermittent diarrhea, pale yellow Or yellowish-green stink and loose, mixed with blood, necrotic tissue or cellulose debris. Prevention, subcutaneous or intramuscular injection of piglet paratyphoid attenuated freeze-dried seedlings, 1 ml per head each time, after weaning injection can produce a stronger immune protection. For treatment, oxytetracycline, neomycin, sulfamethoxazole, sulfadiazine, furazolidone, etc. may be used.
3, viral diarrhea
In the winter season, if diarrhea develops in pigs of all ages, but the symptoms of pigs become lighter and the incidence of piglets is severe, it should be suspected that viral diarrhea has occurred. Common rotavirus disease, epidemic diarrhea, and infectious stomach enteritis. All of the above three viral diseases are mainly characterized by vomiting, dilute feces or watery stools of various colors, and the harm is serious, but there is no specific drug treatment.
To prevent porcine epidemic diarrhea, vaccinated porcine epidemic diarrhoea attenuated vaccine or inactivated vaccine should be pre-inoculated; To prevent transmissible gastroenteritis, intramuscular and intranasal vaccination against porcine infectious gastrointestinal tract should be conducted 45 days and 15 days before sow giving birth. Inflammatory attenuated vaccine 1 ml; Rotavirus disease without vaccine, after the detection of sick pigs, should be isolated as soon as possible, intravenous injection of 5% to 10% glucose saline, add 3% to 5% of sodium bicarbonate, piglets should stop breastfeeding, glucose glycine preparation The solution was used to drink piglets. The formula was: 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 of water.
