Autumn/ Winter worming for your horse

Worming recommendations for your horse will depend on his/hers worming history including: pic 3 of wormers

  • Results of any Faecal Worm Egg counts (FWEC) done through the summer.
  • The wormer’s you have given your horse previously.
  • Whether your horse is pregnant or nursing mare, stallion or foal.

Although Faecal Worm Egg counts are a useful guide to the level of adult worms laying eggs within your horse. A FWEC won’t detect:

  • Encysted or immature larvae.
  • Pinworm; this requires a tape test.
  • Tapeworms; their eggs can sometimes be seen but a blood test gives a more accurate level of infection.
  • Bots; as they emerge as larvae.

The table below is a guide to the horse worming calender, of which worms and when and the chemical group in the wormer required.

Horse’s with good worming history, regularly low FWEC, may have the October to December worming combined in November and re start FWEC in the spring.
