As the saying goes, the disease comes from the mouth, and so does the pig. Pathogens often infect the pig's nose and mouth first, then enter the digestive system through the nose and mouth, and then reproduce in the colon, which hinders the digestion and absorption of nutrients in the pig's gastrointestinal tract. Nutrients and water that can't be absorbed by the small intestine are eliminated from the body, and the effluent contains a variety of pathogenic viruses, which can be repeatedly infected or quickly spread to all pig farms. It is a digestive system disease, which is very harmful to pigs.
After pigs are infected with diarrhea virus, the specific manifestations are watery diarrhea, nausea and vomiting in sick pigs, depression in fat pigs, and watery diarrhea in severe cases. At first, the excrement is gray, and the discharged excrement gradually turns into cold water. Pigs are more resistant. After about a week, the minor symptoms will be slowly repaired.
If the symptoms are biased and the prevention is not timely, the pigs may be eliminated, and the piglets will not be so lucky. If piglets born within a week are infected with diarrhea, they will feel depressed and have symptoms such as nausea, vomiting and diarrhea. Diarrhea is mostly water quality sampling, and piglets die due to severe dehydration, with a mortality rate of more than half or even a large number of deaths. The damage to pig farms is very great, and fattening pigs grow slowly and are poorly managed. Even if they are not dead, they will become a kind of pig.
1 isolate and disinfect pigs in time. After the outbreak of epidemic diarrhea, in addition to actively giving medicine to pigs. If the pathogen is selected correctly and the spread of the pathogen is cut off, it will be more conducive to the treatment of diseases. The sick pigs were first isolated and gathered together. For pigs in a healthy pigsty, build a fence outside and spray quicklime water and live edible alkali for disinfection. Workers need to be disinfected even if they enter or leave danger signs and normal areas, and they should not jump up and down casually to prevent human factors from bringing pathogenic bacteria to healthy pigs.
Pigs can be disinfected directly with quicklime water. After the pigsty of the old sow is disinfected with quicklime, the excrement under the sow's delivery bed is removed, and the road surface needs to be covered with lime powder or caustic soda. After cleaning the pigsty, formalin solution and potassium permanganate solution can be used for disinfection and sterilization.
Once the vaccinated pigs have epidemic diarrhea, they should be vaccinated with the whole pig vaccine of inactivated epidemic diarrhea vaccine as soon as possible while being isolated, and be immunized again two weeks after vaccination and two weeks before delivery of pregnant sows. The old sow who is pregnant for 70~75 days has another injection. This kind of pig should adopt fetal immunity to develop immunity. Generally, vaccination should be carried out on time until there are no diarrhea piglets in all pig farms for about 60~65 days, and vaccination can be terminated.
3 after controlling the amount of food, people like feed very much and often don't know if they are full. At this stage, attention should be paid to controlling the amount of feed, so that piglets can only eat 80% full and can slowly relax and eat freely after reaching 50~60 kg, especially after epidemic diarrhea occurs in the pig farm. The amount of feed for healthy piglets in this pig farm must be strictly controlled.
4 Comprehensive prevention and control treatment Add Astragalus polysaccharide oral liquid+concentrated probiotic oral liquid+multi-dimensional oral liquid to the drinking water of pigs to prevent mixed infection of other diseases in pigs. At the same time, traditional Chinese medicine preparations such as intestinal peptide were mixed into the feed. Before and after weaning, adding 200 grams of intestinal peptide to every 50 kilograms of feed and adding 15-25 kilograms of suckling piglets to every 50 kilograms of feed has certain control effect for 3-5 days. There is no specific medicine for swine epidemic diarrhea. In addition to active vaccination, symptomatic treatment can also be used to supplement body fluids to prevent dehydration, and antiviral drugs can also be used to alleviate the condition.
