Assessing breeding herd status: production data

摘要

Porcine reproductive and respiratory syndrome (PRRS) virus has provided innumerable challenges to practitioners and continues to test our resolve. Numerous diagnostic tests are available to identify the PRRS virus, viral antigen, viral RNA and antibodies. Also, varied management strategies are employed to stabilize reproductive herds in hopes of producing offspring without active infection. Similarly, management strategies and serology are utilized to categorize sow herds for health matching to commingle offspring or formulate intervention strategies. The objective of this presentation is to complete the circle by discussing the use of production records to categorize reproductive herds according to their PRRS status (i.e. recovered vs. chronic).
