Abstract

Subclinical ketosis is a metabolic disease that has been associated with reduced milk production, and impaired fertility. Duffield et al (2001) have reported a median prevalence of subclinical ketosis of 41% among 25 Ontario Holstein herds, and a within-herd prevalence ranging between 8 and 80%. Our study was designed to evaluate the use of a milk strip test as a cow-side test for detection of subclinical ketosis, and to discuss its potential practical application to a herd health-monitoring program.
