Treatment of plant poisoning in goats
  • Remove the plant from the goat - empty its mouth if possible.
  • Keep the goat walking slowly so that it doesn’t settle and start cudding.
  • Give large quantities of strong cold tea. The tannic acids will precipitate many of the alkaloids and salts of heavy metals. Strong coffee will have similar effects.
  • Don’t dose a vomiting goat.
  • Don’t give tea to a goat that has been poisoned with acorns that are full of tannic acid already.
  • Give large doses of liquid paraffin (500ml) as a first aid remedy.
  • Treat for shock - keep quiet and warm.
  • Try to identify the source of poison to tell the vet.
  • Give a mixture of eggs, sugar and milk to soothe and relieve irritation of the stomach linings.
