How to prevent and cure swine intestinal plague

Classical swine fever, commonly known as intestinal plague, is one of the infectious diseases that seriously endanger pig industry. Classical swine fever virus (CSFV) is RNA virus belonging to pestivirus genus Flaviviridae. Classical swine fever is an acute, febrile and highly pathogenic infectious disease caused by RNA virus, which is widely distributed and harmful. Classical swine fever spreads rapidly, with high morbidity and mortality. Swine is the only host of CSFV. The main infectious source of CSFV is infected pigs and infected animals. Direct contact between susceptible pigs and infected pigs is the main way of virus transmission. Often with the disease pig manure urine, mouth, nose, eye secretions will carry the virus out of the body, pollution pen, feed, drinking water and utensils.

When CSFV first infects susceptible pigs, acute outbreak occurs. Subacute and a few chronic cases followed slowly. In the later stages of swine fever, secondary infections with Salmonella cholerae and Pasteurella suis were common, accompanied by paratyphoid fever and swine pneumonia.

Sick pigs have elevated body temperature, shortness of breath and listlessness. Eye view can be seen: ear root, thigh lateral, abdominal, hip skin has a large number of flaky bleeding points, purple.

There is no specific medicine for classical swine fever. Emergency inoculation of anti-classical swine fever serum to pigs without disease can protect pigs. Swine that has been infected should be isolated and culled.

Prevention of swine fever:

(1) Isolation of sick pigs: sick pigs, sick pigs and pigs without clinical symptoms shall be raised separately to reduce the transmission of pathogens.

(2) Strengthen disinfection: pigsty needs to be completely and thoroughly disinfected, and it is best to use different disinfectants alternately.

(3) Strengthen feeding management: give pigs nutritious and digestible feed, and do a good job in health care.

(4) Adhere to self-propagation and self-cultivation: strictly control the source of infection, purify the pig farm, and strictly prevent the introduction of viruses when introducing.

(5) Establish immunization procedures: immunization procedures should be established according to the pig farm's own conditions, injection conditions, and maternal antibodies.
