If pig farmers want to get a good profit in the whole year, they must ensure that their pigs are less ill, very healthy and healthy. The healthier the higher the yield, the better the sale and the more income, so today's Huinong.com Xiaobian prepared the most common preventive measures for the five major diseases in the process of raising pigs! E.coli Escherichia coli is mainly caused by carrying pathogenic Escherichia coli, such as piglet chalk disease and piglet edema disease. In the case of piglet chalk disease, in the prevention and treatment of the disease, the sow must be fed a live vaccine before the birth of the sow, and the sow is re-immunized after half a month of production. In the treatment of piglet edema disease, sows need to be injected with active vaccine to improve the immunity of the sow. At the same time, improve the quality of the management work of the sows and piglets, clean the pig houses regularly, and ensure the ventilation in the pig houses. Under normal circumstances, the sows are injected with E. coli vaccine one and a half months after the production, and the piglet feeding work is prepared in advance. Once piglets are infected with E. coli, they must be anti-inflammatory and antibacterial to piglets, combined with treatments such as heart and rehydration to ensure that piglets have sufficient vitamins. Piglet paratyphoid Piglet paratyphoid fever is mainly caused by infectious diseases caused by Salmonella, most of which occur in piglets less than 4 months old, rarely in pigs of more than 6 months, and the infection time does not have very obvious seasonal characteristics. Piglets will have constipation and red skin in the early stage of paratyphoid fever. In the later stage, the skin has a blue-purple problem and the body temperature is relatively high. In the prevention and treatment of piglet paratyphoid, piglets must be vaccinated with a paratyphoid attenuated lyophilized vaccine after weaning. The piglets are first immunized within 30 days and re-immunized after one week. In the treatment of piglet paratyphoid, the effect of oxytetracycline and erythromycin is not ideal, and it is more suitable for gentamicin treatment. Swine fever Hog is a common swine disease in spring, with high mortality and contagiousness, mainly due to acute infectious diseases caused by swine fever virus. Hog Cholera is a common disease that can occur in any pig and is susceptible to swine fever. Relatively speaking, piglets are less likely to contract swine fever within a month. The main reason is that due to the high infection performance of swine fever, once the swine is infected with swine fever, it is very prone to large-scale infection and accompanied by higher mortality. Under normal circumstances, piglets are mainly found in the spring, and they need to be highly concerned by farmers, and then take targeted measures. In the prevention and control of swine fever, the sows need to be immunologically treated before and after breeding. The piglets can be immunized for the first time in one month, and the piglets are then immunized again after two and a half months. In addition, the spring temperature has not been stabilized. Before the spring, the breeding needs to be done in advance to prevent the moisture in the pig house. Improve the hygiene management level of pig houses, disinfect the pig houses regularly, and disinfect them with soda water and grass gray water. Improve the level of pig feed management, increase the amount of succulent feed culture, and thus improve pig immunity. Swine flu Swine flu is a kind of respiratory disease that is often built in the spring, mainly caused by swine flu virus. The main clinical symptoms of swine flu are fever and difficulty breathing. Swine flu is recovering quickly, mainly through the respiratory tract. The characteristics of the disease are relatively short. Once the swine flu problem occurs, the swine flu problem will occur in the entire pig house, which is 100%. In the comprehensive prevention and control of swine flu diseases, farmers need to improve the management level of swine flu, and prevent other diseases such as pneumonia and pleurisy in pigs, which will increase the mortality rate of pigs. At present, the swine flu vaccine is not effective in treating swine flu, and it is necessary to vaccinate the swine flu multiple times, thereby effectively improving the immunity of the pig. In the spring prevention and control of swine flu, due to the low temperature stability in spring, it is necessary to improve the ventilation performance of the pig house and improve the moisture level. It is strictly forbidden to change the temperature of the pig house to ensure that the pig can grow in a relatively stable temperature environment. At the same time, farmers need to sterilize the houses on a regular basis. Special attention should be paid to the fact that pigs are not allowed to introduce new pigs during this period. If new pigs must be introduced, they should be kept in isolation and observe for a period of time. Feeding. The pig feed is equipped, and the farmer can apply the additive in the feed according to the local conditions of the pig breeding, thereby improving the immunity of the pig. Pig farmers know that spring is the main period of pig disease outbreak. If improper management and disease outbreak, it will not only cause serious negative impact on pigs, but also cause large-scale death of pigs, which will seriously affect the economic benefits of farmers. Therefore, the prevention measures for pig farmers are best done from the beginning of the year, with prevention as the core concept to ensure that the pigs they raise can grow healthily during the year.
