Optimising performance through wholistic health and therapy

Monitoring the worm burden of your horses will allow you to treat or NOT treat your horses for worms in the most effective way.

 It is necessary to keep wormcounts low in horses to avoid health issues including weightloss and colic, and also to reduce paddock contamination. Worming when not necessary, however, is costly an promotes the development of resistance to currently available worming chemicals.

When should I get a worm count?

  • Prior to worming, to determine whether or not your horse requires the use of a chemical wormer.


  • Regularly, to work out a 'worm infestation' pattern for your horse. Once you have information regarding the times of the year your horse has the highest and lowest worm burdens you can formulate a yearly treatment plan for your specific information.


  • To test for wormer resistance. To do this you must conduct a Faecal Egg Count Reduction Test (FECRT). This involves submitting two samples - one prior to worming, and the second, two weeks after the administration of the wormer. This will give you an indication of the effectiveness of the wormer you are using.


 A common approach to worming all horses is not an approprate way to manage worm infestations in horses. Management/Keeping of horses is so variable (stables/yards/paddocks/individual/herd etc.), that different recommendations should be tailored to each particular environment rather than a set of universal recommendations.
