Individualized Deworming: How it’s done

The new American Association of Equine Practitioners (AAEP) Parasite Control Guidelines recommend moving away from traditional deworming practices of treating all horses with the same dewormer at the same time.

Individualized Deworming (ID) is an advanced approach to parasite control, based on the knowledge that every horse has a unique set of conditions and needs.

Work with a veterinarian to complete the following steps, and you will be equipped with the knowledge you need to design and introduce the most e?ective parasite control plan possible.

  • Step 1:

    Establish baseline egg counts

    Fecal egg counts (FECs) can establish a horse’s parasite status. This will help determine if the current deworming program is working properly.

  • Step 2:

    Measuring shedding levels

    Performing FECs on the herd (or 10% of a large herd) will help determine shedding levels. Shedding levels help identify which horses pose a greater risk of exposing others to parasite infection.

  • Step 3:

    Know your variables

    Parasite risk evaluation is integral to successful deworming strategies. All horses carry unique risk factors that a?ect their vulnerability to parasites. These risks may include: age of horse, climate, manure removal, pasture rotation, problem parasites, transportation, horse density, type of pasture, housing, feeding and how a horse is used.

  • Step 4:

    Determine a horse’s ID

    Analyze the data collected from your horse, herd and farm to customize an easy-to-follow plan that fits the individual needs of your horse.
