Summary and Implications

The accuracy of genomic prediction for antibody response to Porcine Reproductive and Respiratory Syndrome (PRRS), measured as S/P ratio, was evaluated using two independent datasets of Landrace x Large White females. Results demonstrate that antibody response during a PRRS outbreak can be predicted with high accuracy using genetic markers in two regions on chromosome 7. One of these regions includes the Major Histocompatibility Complex. The high accuracy for this region indicates that marker effects are consistent across Landrace x Large White populations.
