Porcine reproductive and respiratory syndrome

Update Time:2023/7/5
Porcine reproductive and respiratory syndrome
PRRS is an acute, highly contagious viral disease characterized by PRRSV, also known as Pig Blue Ear Disease. It is a porcine infectious disease that seriously affects economic benefits.


Spread Features
PRRS is an acute, highly contagious viral disease characterized by reproductive impairment and respiratory symptoms caused by PRRSV.

The disease spreads more easily among piglets than among adults. When healthy pigs are in contact with sick pigs, as if they are raised in pens, they are frequently transported and highly concentrated, which can easily lead to the occurrence and prevalence of this disease. Poor hygienic conditions, bad weather and high stocking density in pig farms can promote the prevalence of porcine reproductive and respiratory syndrome.

Most pigs of various ages showed symptoms of dyspnea after the onset, but the specific symptoms were not the same.

After the sows are infected, they will have cold-like symptoms such as anorexia, elevated body temperature, shortness of breath, and runny nose at the initial stage. Sows in the early pregnancy will abort, and sows in the second trimester will have stillbirths, mummified fetuses, or give birth to weak or deformed fetuses. , Lactating sows have no milk after giving birth, and most of the suckling pigs are starved to death.

After infection, boars showed coughing, sneezing, depression, loss of appetite, shortness of breath and movement disorders, decreased libido, decreased semen quality, and less ejaculation.

After growing-finishing pigs and weaned piglets are infected, the main symptoms are anorexia, lethargy, coughing, and dyspnea. Some pigs have swollen eyes, conjunctivitis and diarrhea, and some weaned piglets have diarrhea, arthritis, red ears, and spots on the skin.

After the lactating piglets are infected, they often show rough coat, lack of energy, dyspnea, panting or ear cyanosis, and some have bleeding tendency, plaques under the skin, arthritis, sepsis and other symptoms, and the mortality rate is as high as 60%.
