Viremia: It’s a Complex World
Pork production is complex and adding to that, on the herd health side, is viremia.
Genetic Selection May Reduce Incidence of PCVAD
The incidence of PCVAD can be reduced by selecting for 65-day weight along with porcine circovirus (PCV2) viremia and antibody titers, conclude Jared S. Bates, University of Nebraska, and colleagues in their report, "Selection for Immune Responses to Porcine Circovirus (PCV2) to Decrease Incidence of Porcine Circovirus Associated Disease."
Viremia Control Crucial for PCVAD
Porcine circovirus associated disease is a challenging and costly disease for the U.S. pork industry today.
Viruses Reported in Philippines Pigs
The USDA's Plum Island Animal Disease Laboratory has isolated an atypical porcine reproductive and respiratory syndrome virus from swine samples collected from pigs from four farms north of Manila.
Oral Circovirus Vaccines Studied
Although effective commercial porcine circovirus type 2 vaccines are available to the nation’s pork industry, the study for even more protective vaccines continues.
The U.K. Pig Industry: What History Tells Us
We can’t turn the clock back, but we can learn from history and how a country’s swine industry has evolved — or devolved — and learn by others’ mistakes.
PVC2: Lessons learned and the future
Attention surrounding porcine circovirus associated disease is not likely to end any time soon. While there are many answers yet to find, some can help plan future strategies.
PCVAD vaccines reduce mortality
Early dosing with approved vaccines could reduce mortality rates for porcine circovirus associated diseases, says Tom Gillespie, DVM, Renssalaer Swine Service, Rensselaer, Ind.
Brochure and DVD Provide PCVAD Insights
The American Association of Swine Veterinarians and the National Pork Board have collaborated to create “A producer’s guide to managing porcine circovirus associated disease.”
PCV2 Vaccine Trials Look Promising
Kansas State University researchers have evaluated what appears to be a promising vaccine against porcine circovirus Type 2, a virus that researchers predict infects every swine herd in the United States.
