As many as 50% of dairy cows are at risk of ketosis, with most cases occuring 2-3 weeks after calving. Ketosis can lead to reduced milk yield, weight loss, immunosuppression and many other diseases. As much as 9.5 litres of milk can be lost each day in cows at the upper threshold (2.9mmol/L) of subclinical ketosis. In this video we shall discuss the importance of monitoring ketone levels in cows using the CentriVet Bovine Ketone Meter from Rapid Labs.
