Porcine Reproductive and Respiratory Syndrome PRRS is a critical concern for the United States, as well as the global pig industry. The annual cost of this virus in the U.S alone stands at over $600 million. This highly contagious viral infection can result in diminished fertility rates, a significant rise in abortions, stillbirths, weak live births, and mortalities among piglets.
The respiratory aspect of PRRS may cause severe symptoms in young pigs when other pathogens are present, leading to high mortality rates amongst suckling and weaned pigs. In some cases, the disease might manifest apparent signs.
Preventing PRRS
The primary strategy for preventing this disease is mntning strong biosecurity measures:
Quarantine incoming breeding stock with thorough testing.
Use semen from PRRS-free sows for breeding to reduce the risk of virus entry.
Ensure proper sanitation on transport vehicles and implement strict boot disinfection procedures.
Conduct regular hygiene checks.
Signs of Illness
The symptoms associated with PRRS vary based on the viral strn and the age of the pig:
In adults, common signs include loss of appetite, fever, premature farrowing or abortion, unsteady gt, circling movements, falling to one side, and eventual death.
For affected litters, increased stillbirths, high mortality rates among suckling pigs, mummified fetuses, weak-born piglets, and runny eyes may be observed.
In weaned pigs, loss of appetite, lethargy, flure to gn weight, difficulty breathing, and blotchy reddening of the skin are indicators that require attention.
Diagnosis Treatment
Differential diagnosis necessitates sample submissions to a veterinary diagnostic laboratory. It's recommed for pig owners to consult with their veterinarian for assistance in identifying PRRS.
Health Concerns
There is no documented evidence suggesting diseases associated with PRRS.
