Comparative Evaluation of Different Blood Collection Sites for the Assessment of Beta-Hydroxybutyric Acid Concentrations Using a Handheld Meter in Sheep.

ABSTRACT: Hyperketonaemia is a common problem in periparturient sheep. This study aimed to evaluate the performance of FreeStyle Optium Neo H (FS) for measuring blood β-hydroxybutyric acid (BHBA) concentrations in sheep. Whole-blood BHBA concentrations were measured using the FS from the jugular and ear veins of 175 clinically healthy, late-gestation (n = 56) and postparturient (n = 119) ewes. Jugular blood serum samples were also used for the reference sampling site. Blood BHBA concentrations measured with the FS from the jugular and ear veins showed a high positive correlation with the serum concentrations measured using the reference method (r = 0.84, r = 0.81, respectively). According to the Bland-Altman plot and limits of agreement, when compared to the reference method, FS recorded lower BHBA
