Autumn pig farm infectious disease is high, pig three infectious diseases prevention and control!

Classical swine fever, swine erysipelas and swine plague are the three major infectious diseases in pigs. In China, the total mortality rate of pigs is about 80% of the total, and the mortality rate of pigs is 5%. Therefore, we should raise the level of prevention and control of pig diseases. If we can reduce the total mortality rate by one percentage point a year, that is to say, it is equivalent to increasing the slaughter of 5 million pigs. What a great fortune it is!

According to the relevant data, the cause of death in pigs is about 80% of deaths, while infectious diseases account for 70% to 80% of all diseases in pigs. Among them, CSFV, swine erysipelas and swine plague accounted for 70% of infectious diseases in pigs. Therefore, in the prevention and control of swine diseases, the prevention and control of these three diseases is the top priority.

Because the swine fever virus vaccine developed in China is one of the most advanced vaccines in the world, the epidemic prevention effect of CSF Dan vaccine, hog cholera swine erysipelas vaccine, swine fever erysipelas and swine plague triple vaccine produced by various designated pharmaceutical factories in China is relatively reliable. All three diseases can be effectively controlled in accordance with the scientific immunization procedures and the areas where scientific vaccination is maintained. However, some grass-roots veterinarian epidemic prevention teams in some areas are unstable, and the epidemic prevention density of pigs is not guaranteed. In some areas, the immunization procedure did not keep up with the changes in the pig raising situation, and there was a phenomenon of vaccination after vaccination. In some areas, there was atypical swine fever. In some areas, two vaccines were used for a long time, which caused the occurrence of pig lung disease and caused undue losses to the local pig industry.

Prevention and treatment of piglet stage blight

The mortality rate of piglets born from 1 weeks to 2 weeks after birth is 65% of that of the whole piglets, while the mortality of piglets is 70% of the lifetime mortality.

1. the onset is related to feeding management. Improper cold and warm keeping of newborn piglets can easily cause cold, diarrhea and even death of piglets. Improper calcium supplementation and dilute hydrochloric acid can cause piglets anemia and indigestion.

2. most of the piglets are red dysentery, yellow dysentery, white dysentery, paratyphoid fever and edema disease.

Maternal antibody titers were low or no maternal antibodies.

Sow is in poor health.

The hygienic condition of piggery is poor.

The piglets were not vaccinated or prevented by the relevant vaccination procedures.

3. the growth and development speed of piglets, especially the survival rate at weaning and the weight of weaning nest, are important indicators to evaluate the efficiency of a pig farm. In the piglet stage, once the piglets are attacked, even if they are healed by treatment, the growth of the piglets will still have a great impact on the fattening stage, and some of them will form stiff pigs.

Prevention and control of epidemic diseases should be divided into priorities and priorities.

1., priority should be given to the prevention of epidemics. Infectious diseases such as piglets colibacillosis, swine fever, swine erysipelas, swine plague, piglets paratyphoid, Streptococcosis, asthma and so on are mostly vaccinated. They should be vaccinated according to their immunization procedures to avoid the time of cross inoculation.

2., we should prioritize the treatment of diseases. When infectious diseases and common diseases occur at the same time, infectious diseases should be the most important. When two kinds of infectious diseases occur at the same time, heavy infectious diseases and zoonosis should be emphasized.
