Oak (Quercus spp.) Toxicosis
ToxicologyBovineNew
Key Points
  • Oak (Quercus spp.) toxicosis is a poisoning that occurs when animals ingest oak plant material
  • Most commonly seen in cows
  • The key toxins are tannins which are broken down into metabolites that cause GI mucosal injury and acute kidney injury
  • Typically starts as anorexia, dullness and discomfort but progressing to diarrhoea, dehydration and signs of acute kidney injury (AKI)
  • Diagnosis is primarily presumptive, based on clinical presentation and the likelihood of oak exposure
  • There is no specific antidote, so treatment focuses on supportive care
  • Restricting access to oak-containing pasture and ensuring adequate forage is key for prevention
Differential Diagnoses
  1. Leptospirosis
  2. Bovine viral diarrhoea (BVD)
