What to Do When Pig Diseases Are Rampant in Winter? Experts Explain the Prevention and Treatment of Common Pig Diseases

Once winter arrives, all breeders must pay attention: if pig farm management is not done well, it can easily lead to a high incidence of pig diseases! So what should be done when pig diseases are rampant in winter? What are the common ones? How to prevent and treat them? The following content is something pig farmers should read carefully!

So to avoid pig diseases in winter, what must be done?

Li Hongguang, a technician at the Animal Husbandry Station of Gaolou Town, Ruian, Zhejiang Province, reminds that winter temperatures are relatively low and the rearing environment is relatively harsh, so disinfection work on pig farms must not be ignored. Daily disinfection of pig farms is the most important epidemic prevention measure. The specific methods are as follows:

1. Environmental disinfection. This mainly refers to disinfection of the main traffic routes, large and small paths, and the areas in front of and behind the pens within the farm. A 2% caustic soda solution or 0.2%-0.3% peracetic acid can be used for high-pressure spray disinfection. Under normal circumstances, disinfect twice a month. For the disinfection pools, all types of disinfection pools on the pig farm should uniformly use 2%-3% caustic soda water, replaced once every 3-4 days, but an appropriate amount of disinfectant must always be kept in the pool. In addition, to prevent hoof disease in breeding pigs, a 1:80 disinfectant solution can be used in the disinfection pool, or the two can be used alternately. Personnel entering and leaving the pig barn must disinfect the soles of their shoes through the disinfection pool.

2. Disinfection for veterinarians and epidemic prevention personnel entering and leaving pig barns. 1. When veterinary and epidemic prevention personnel enter a pig barn, they must disinfect the soles of their shoes in the disinfection pool and wash and disinfect their hands in the disinfection basin.

2. When leaving the barn, they must wash and disinfect their hands in the disinfection basin.

3. After veterinary and epidemic prevention personnel finish work in one pig barn, they must wipe around the syringes and medicine boxes with gauze soaked in disinfectant, and only after disinfecting the soles of their shoes and their hands may they enter another pig barn.

3. All-in, all-out empty barn disinfection. 1. First, thoroughly remove all manure, urine, sewage and debris from the pens.

2. Use a high-pressure water gun to thoroughly rinse the ceiling, walls and pen frames from top to bottom.

3. After the water dries, thoroughly rinse with peracetic acid or formaldehyde, or with 2%-3% caustic soda water. After 10-12 hours, thoroughly rinse the pen floor with clean water again. After it dries, spray disinfect with 0.2%-0.3% peracetic acid or 1:800 Xiaodowei.

4. Disinfection. 1. Breeding pig and replacement pig barns should be disinfected once a week; farrowing houses once or twice a week; nursery barns once or twice a week; finishing barns once a week. If an epidemic occurs, the frequency of disinfection may be appropriately increased.

2. Surgical knives, surgical scissors, suture needles and sutures can be disinfected by boiling, or with 70%-75% alcohol. Syringes and needles must be disinfected by boiling.

So what are the common pig diseases with high incidence in winter? How should they be prevented and treated?

1. Swine influenza. This disease mainly occurs in early winter and in late winter and early spring. It often occurs because of uneven cold and warm weather, large temperature differences, weakened resistance of the pig body, and pathogenic microorganisms taking the opportunity to invade.

Prevention and treatment methods: 1. Garlic (or scallion white) 100 grams, crushed and mixed with water, fed once.

2. Egg white 20 milliliters, injected intramuscularly once, once a day, for three consecutive days.

3. Rock sugar 200 grams, millet 250 grams, scallion 50 grams, boiled in water and fed once, once a day, for three consecutive days.

4. Perilla 50 grams, apricot kernels 25 grams, thatch root 75 grams, mint 50 grams, decocted in water and administered once, once a day, for three consecutive days.

5. 30% Analgin 20 milliliters, penicillin 800,000 units, injected intramuscularly once, twice a day, for three consecutive days.

2. Swine enzootic pneumonia. Swine enzootic pneumonia is a chronic infectious disease caused by a filtrable virus. It occurs more often in piglets. In the early stage of the disease, they sneeze. Later they cough and have a runny nose, and the colder the weather, the more severe the coughing.

Prevention and treatment methods: 1. Do not buy diseased pigs, and do a good job of cold protection and warmth preservation for pigs.

2. Oxytetracycline (per kilogram of body weight) 20 milligrams, injected intramuscularly once, twice daily, used continuously.

3. Orostachys 250 grams, honey 100 grams, mulberry bark 100 grams, apricot kernels 50 grams, alum 50 grams, decocted in water and administered once, once a day, for three consecutive days.

4. White sugar 300 grams (melted in warm water), earthworms 10, administered once.

3. Piglet edema disease. This disease is also called intestinal toxemia, gastrointestinal edema, and piglet staggering disease. It is mainly characterized by the appearance of edema and neurological symptoms. Weaned piglets, especially obese piglets, are more susceptible to infection.

Prevention and treatment methods: 1. In late autumn and early winter, strengthen the feeding and management of weaned piglets, especially doing a good job of cold protection and warmth preservation.

2. 10% sulfathiazole 40 milliliters, injected intramuscularly once, twice a day, for three consecutive days.

3. 50% glucose 40 milliliters, 5% ascorbic acid solution 10 milliliters, chloramphenicol injection 750,000 units, mixed and injected intravenously once, once a day, for three consecutive days.

4. Streptomycin 1,000,000 units, penicillin 1,000,000 units, dissolved and injected intramuscularly once, once a day, for three consecutive days.

4. Piglet white scours. Piglet white scours is caused by Escherichia coli. The main symptom is loose feces, which are milky white or grayish white, with a very strong fishy odor.

Prevention and treatment methods: 1. Do a good job of cold protection and warmth preservation, and prevent piglets from eating dirty things.

2. Garlic 250 grams, cooked, mashed and mixed with rice straw ash, fed to the sow and piglets.

3. Goat blood 3 milligrams, injected intramuscularly once.

4. Pulsatilla root 500 grams, gentian 250 grams, charcoal powder 200 grams, decocted into a medicinal soup, fed 15 grams each time, twice a day, given continuously.

If pig diseases are relatively serious, it is still necessary to ask a veterinarian for professional treatment, and carelessness must be avoided. If there are pigs with more severe illness, they should be separated from healthy pigs to avoid a large-scale outbreak of pig diseases.
