As winter weather rolls in, pork industry representatives are reminding producers to maintain strong disease prevention practices.
The virus that causes porcine reproductive and respiratory syndrome (PRRS) is more prevalent in cool, damp, and dark weather, according to a National Pork Association of UK release.
Temperature fluctuations associated with winter ventilation problems also predispose hogs to clinical symptoms of respiratory problems.
PRRS displays itself in the various forms: wasting, sudden death, lameness, nervousness, and lung damage in affected pigs.
Closer to home, Swine Health Ontario (SHO) highlights the prevalence of the disease in Ontario.
“PRRS remains a disease of significant economic impact in Ontario,” says Lori Moser, SHO manager. “Currently, 30 to 40 per cent of the approximately 1,200 sites enrolled in the OSHAB PRRS ARCE program are PRRS positive.”
