Abstract

A field study was conducted to evaluate the efficacy of a monensin controlled release capsule (Rumensin CRC) for the prevention of subclinical ketosis in lactating dairy cattle. A total of 1011 cows from 25 Holstein dairy herds in southern Ontario were enrolled in this trial. Allotment of treatment and placebo capsules were randomised within farm and the capsules were administered approximately 21 days prior to expected calving date.
