Minimizing the Risk for Ketosis

Introduction

Although most cases of ketosis occur in fresh dairy cows, feeding practices and cow health prepartum can predispose cows to experiencing ketosis after calving. Most cases of primary ketosis occur within the first 2 weeks of calving, and even most secondary ketosis (occurring after the onset of another disease) occurs within the first 30 to 60 days in milk. In general, less than 5% of the cows in a herd should experience clinical ketosis. However, some reports have indicated that the incidence of subclinical ketosis may affect 40% of cows, with the incidence rate varying widely among farms, and may be as high as 80% on individual farms.

The major focus prepartum to reduce the risk for ketosis after calving is maintaining feed intake in late gestation and avoiding overconditioning cows during late lactation and the dry period. [Read more…]
