Sensitivity: the percentage of boars that were correctly identified by the test based on litter size. Specificity: the percentage of boars that tested as truly negative. The positive predictive value: the percentage of boars that tested positive but actually had a litter size ≥11 or <11 (Landrace), litter size ≥12 or <12 (Yorkshire), or litter size ≥8 or <8 (Duroc). The negative predictive value: the percentage of boars that tested negative but actually had a litter size ≥11 or <11 (Landrace), litter size ≥12 or <12 (Yorkshire), or litter size ≥8 or <8 (Duroc).
