Oak leaves and acorns

Whilst ruminants are more susceptible to acorn poisoning, outdoor pigs may be affected occasionally. Young oak leaves or green acorns are the major sources and signs are seen two to three days after ingestion. These include abdominal pain and constipation followed by haemorrhagic diarrhoea. The kidneys may also be affected.


  • There is no treatment but remove the pigs from the sources immediately.
