Optimization of a milk pregnancy-associated glycoprotein enzyme-linked immunosorbent assay test for pregnancy in Holstein cows using time-dependent cut-points between 23 and 90 days after insemination

Optimization of a milk pregnancy-associated glycoprotein enzyme-linked immunosorbent assay test for pregnancy in Holstein cows using time-dependent cut-points between 23 and 90 days after insemination

ABSTRACT: Our hypothesis was that the accuracy of a commercial milk pregnancy-associated glycoprotein (PAG) ELISA test using the same thresholds at all stages of gestation would be improved by adjusting the cut-points according to the number of days since last breeding (DSLB) between 23 and 90 d aft...
