Abstract

Ketosis is a common disease of periparturient dairy cows. Ketosis is defined as an increased concentration of beta-hydroxybutyric acid (BHBA) in the serum. There is strong evidence that cows with mild ketonemia (above approximately 1.1-1.4mmol/l) are at an increased risk of other disease (e.g. displaced abomasum), decreased milk production and infertility. Diagnosing ketosis is important because it has a financial cost and at the herd level, reflects feeding and management. The objective of this study was to assess the accuracy of a newly available BHBA assay (Precision Xtra®), marketed for human diabetic patients, by comparison to the gold standard test. This new device has potential to be a quality cows-side test for monitoring subclinical ketosis in dairy cattle. An additional objective was to assess the accuracy of the Ketostix® test.
