<FlashCard questions="4">
|q1=What conditions would you consider? (Most likely first.)
|a1=
The most likely conditions to consider include: nervous acetonaemia/ketosis;
left-displaced abomasum and secondary acetonaemia; traumatic reticulitis; sub -
acute ruminal acidosis.
|l1=Ketosis_of_Cattle
|q2=How could you confirm your diagnosis?
|a2=
Diagnosis of ketosis is based on clinical examination and confirmed by a
positive Rothera’s reagent test or laboratory demonstration of a 3-OH butyrate
concentration in excess of 4.0 mmol/L (40 mg/dL). Plasma glucose and NEFA
concentrations are too variable to confirm a diagnosis of ketosis. No biochemical
test differentiates between primary and secondary ketosis. It must be ascertained
that the cow does not have a left-displaced abomasum.
|l2=Ketosis of Cattle#Diagnosis
|q3=What treatment would you administer?
|a3=
Treatment includes dexamethasone and 400mL 50% dextrose administered
intravenously. Propylene glycol is given orally twice daily until normal appetite
returns. The cow was eating well the following day.
|l3=Ketosis of Cattle#Treatment
|q4=How could this condition be prevented?
|a4=
Control measures include feeding molasses-treated chopped straw<sup>1</sup> as part of the ration during the dry period to maintain rumen size and microbial function. Dry matter intakes should be as high as possible during the dry period, and on the day of calving in particular. There must be 24 hr of easy access to the diet – one should not rely on feeding refusals from the milking herd ration to the dry cows. Any dietary changes must be introduced gradually. Most high-yielding cows are fed a total mixed ration which has the benefit of creating a more stable rumen environ - ment than that achieved with separate concentrate feeding. Cows should enter the dry period in BCS 3 (scale 1–5) and maintain that value until calving.
