  1. Sensitivity and specificity and the ability to predict sheep PLS is compared between ultrasonography and regression models of blood metabolite biomarkers. Most biomarker panels offer a higher sensitivity and specificity than that of ultrasound diagnosis of PLS. The values calculated for ultrasound are for detecting pregnancy status (CNT vs PRG) and whether the pregnant ewes carry a single fetus or more (SNG vs MLP) while, the biomarker panels also identify the specific number of the litter (i.e., SNG, TWN, TRP).
