How to prevent and control pig diseases? Prevention and Control Technology of Pig Diseases

Many farmers who have just begun to expand the scale of farming have encountered such a problem, that is, how to prevent and control diseases? The more large-scale breeding, the more important the disease prevention and control technology of pigs. So today we are going to talk about pig disease prevention and control technology.

Types of common diseases in pigs

1. Classical swine fever

Commonly known as "intestinal rotting fever", it is one of the main infectious diseases that threaten the pig industry, characterized by acute, septic changes, intra-organ bleeding, necrosis or infarction, chronic fibrotic necrotizing enteritis, and secondary paratyphoid and pasteurellosis in the later stage.

two。 Swine erysipelas

Porcine erysipelas is erysipelas, which is characterized by persistent high fever, acute septicemia and skin rash. It is a gram-positive bacteria with an obvious tendency to form filaments. It is a straight or slightly curved microbacillus with a size of about 0.2-0.4 microns. This kind of bacteria is extremely resistant to natural environments such as fire fumigation, dryness, decay, and sunlight. The bacteria can still survive in the liver and spleen of pigs after death.

II. Measures for prevention and control of pig diseases

1. Control measures of Classical Swine Fever

When pigs are initially infected with classical swine fever, they like to drill into the pigsty, lose their appetite, and their body temperature rises gradually, accompanied by diarrhea, stool and other symptoms. Once the symptoms of classical swine fever occur, sick pigs tend to die gradually within a week, and the mortality rate is as high as 90%. Therefore, in view of classical swine fever, Luodian County, Guizhou Province Agricultural Technology Integrated Service Center reminded the majority of farmers that there are two most effective prevention and control measures for classical swine fever.

(1) it is necessary to vaccinate all the pigs in the breeding plant in the early stage of breeding to avoid a full outbreak of the disease.

(2) if it is found that any pig is unfortunately infected with swine fever, the breeding personnel should immediately carry out isolated breeding, take corresponding disinfection, and inject "Shuanglian Classic + Anning", according to the amount at 1:1, once every three days, to ensure that the fever is reduced and the infection is prevented, the diseased pigs should also be fed with drugs such as plague virus Kuaike, and treatment measures should be taken to provide comprehensive protection to the diseased pigs. If the swine plague infected by pigs is serious, measures such as incineration, deep burial and culling should be taken immediately to prevent the virus from spreading to other pigs, which not only ensures the personal safety of breeders, but also prevents black-hearted merchants from sending diseased pork to the market through treatment.

two。 Prevention and control measures of swine erysipelas

In view of swine erysipelas disease, effective prevention and control measures should be taken to avoid the high mortality of pigs and ensure the overall economic benefits. Taking the Agricultural Technology Comprehensive Service Center of Luodian County, Guizhou Province as an example, they have two measures for the prevention and control of porcine erysipelas.

(1) the most effective prevention and control measure is to inoculate pigs in breeding places with antibodies against porcine erysipelas. When vaccinating swine erysipelas, attenuated or inactivated vaccines are usually selected to prevent the breeding of virus infection.

(2) if it is found that the virus has been produced in pigs, the most effective treatment is to inject penicillin and add porcine erysipelas-specific serum to diseased pigs, and the diseased pigs should be isolated immediately and fed separately to prevent the virus from spreading through shared water sources, food troughs, food, etc. The above two methods can effectively inhibit the growth and reproduction of the virus and its spread in a large area, and ensure the health and safety of pigs.

Although pig prices have been in the doldrums recently, in the long run, due to the improvement of economic and living standards, the meat intake of urban and rural residents has increased steadily, and the pig farming industry still has a lot of profit space. I hope that with the protection of disease prevention and control technology, we can have better benefits.
