To keep worming simple yet effective we recommend using the protocol shown in the image below.

Planning your worming strategy

Careful consideration should always be made when choosing when and how to worm horses. In order to make this decision process more transparent we have devised two simple worming strategies – the Periodic and Strategic worming plans. Have a look at the flow diagram below to see which plan is best for you and your horse.

    Periodic Plan

    The Periodic Plan

    At least 2 Worm egg counts a year, with use of ‘wormer’ during early spring and autumn + a further mid summer as required.

    Tapeworm treatment twice a year.

    Strategic Plan

    The Strategic Plan

    3 Worm egg counts a year, a Tapeworm Blood at least once a yearr – use of any ‘wormer’ only as required.

What to worm with after the worm egg count

  • No visit charge for 10 or more horses

    Only £9 (per horse) for a worm egg count done on the yard

  • During the Spring and Autumn

    Less than 200 eggs per gram – We just recommend a single tapeworm treatment.

    Between 200-500 eggs per gram – We would recommend a Noropraz (or combined Ivermectin and Praziquantel based product). If this product has been used recently we will recommend an alternative.

    Over 500 eggs per gram – we would recommend an Equest Pramox (or combined Ivermectin and Praziquantel based product). If these products have been used recently we will recommend an alternative.

  • During the Summer

    Less than 200 eggs per gram – We recommend no treatment apart from continued pasture management.

    Between 200-500 eggs per gram – We would recommend a Noromectin (or another Ivermectin based product). If this product has been used recently we will recommend an alternative.

    Over 500 eggs per gram – we would recommend an Equest (or Moxidectin based product). If this product has been used recently we will recommend an alternative.
