2. She calved about 3 weeks ago and has gradually gone off her concentrate ration since then.
3. The farmer reports she seems dull and is losing condition, although she is still drinking.
4. On examination, the cow is quiet, mildly dehydrated, and has reduced rumen fill.
5. A cow-side test detects elevated ketone bodies in the milk and urine.
6. The problem has developed in early lactation during negative energy balance.

Diagnosis

Bovine Ketosis

Bovine ketosis is common in high-producing dairy cows in early lactation, when energy demands exceed intake. Clinical signs include reduced appetite, decreased milk production, weight loss, and ketonaemia or ketonuria.
