Introduction

  • Cause: autoallergic reaction (anaphylaxis) to the cow’s own milk extract (casein).
  • Signs: generalized or local (on the eyelids and muzzle) urticaria with or without piloerection. Other signs include dullness, recumbency, shuffling gait, ataxia, muscle tremors, coughing, respiratory distress, restlessness, tail swishing, abdominal watching, abdominal licking, abdominal kicking, vocalization and maniacal behavior.
  • Diagnosis: based on history of being recently dried off or milk retention and clinical signs.
  • Treatment: administration of antihistamines (if licensed in geographical location) and anti-inflammatories.
  • Prognosis: good for recovery, but likely to reoccur in the future.

Pathophysiology

  • The exact physiological mechanism that initiates the autoallergic reaction is unknown.

Timecourse

  • Occurs within hours of dry off or retention of milk.
