'''After a stormy autumn night you are called to attend a recumbent 10-year-old Simmental-cross-Friesian beef suckler cow that calved 36 hrs ago. The cow is at pasture with a group of predominantly summer-calving cows which is receiving no supplementary feeding other than barley straw in a ring feeder. The cow was found by the farmer to be in lateral recumbency and ‘thrashing wildly’. When you arrive the cow appears quiet but clinical examination precipitates seizure activity.'''

<FlashCard questions="4">
|q1=What conditions would you consider? (Most likely first.)
|a1=The most likely conditions to consider include: <br>
*hypomagnesaemia
*hypocalcaemia
*lead poisoning
*bovine spongiform encephalopathy.
|l1=Hypomagnesaemia
|q2=What treatment would you administer immediately?
|a2=While unlicensed for use in cattle, 6–8 mL of 20% pentobarbital solution injected intravenously controls seizure activity a great deal more effectively than either diazepam or xylazine. <br>
The cow is then haltered and 50 mL of 25% magnesium sulphate is added to a bottle of 400 mL of 40% calcium borogluconate solution and given by intravenous injection over 10 minutes. <br>
The remaining 350 mL of the bottle of 25% magnesium sulphate solution is given subcutaneously in two divided sites immediately behind the left shoulder. <br>
The cow was able to maintain sternal recumbency when pulled upright after all treatments had been administered and walked off to find its calf after a further 20 minutes.
|l2=
|q3=What samples would you collect?
|a3=A serum sample for calcium and magnesium concentrations should be collected in case the cow does not respond to treatment.
|l3=Hypocalcaemia
|q4=What control measures could be adopted for the remainder of the herd?
|a4=The farmer was advised to start feeding 2 kg per head per day of highmagnesium concentrates immediately. Good-quality barley straw should also be ''available ad libitum.''
|l4=
