DOSING REGIMES FOR HORSE WORMER

 

We now offer in-house worm egg counts. This is the most accurate way to determine whether your animal requires to be wormed. Worm egg counts can be perfomed in place of routine worm dosing and therefore wormers are only administered when necessary. Please discuss frequency of testing with one of our vets. Frequency will depend on number of horses, type of yard and any previous results.

Listed below are examples of timings of dosing during the grazing season depending on the family of wormer chosen. Regardless of the type of wormer in use all dosing regimes should include, in March and 6 months later in September, a tapeworm treatment using either Strongid P, or Pyratape P at double dose. The same wormer should not be used for consecutive years to try to reduce the build up of resistant worm populations. We recommend using a four year cycle of the regimes listed below.

NB. The dates of the preceding doses determines the exact start in March.

 

STRONGID P or PYRATAPE P (4-6 week intervals)

Double dosing on March the 31st, followed by repeat dosing at 6 week intervals on May 14th, June 25th, August 6th, and double dosing again on the 17th September.

For young stock use Pyratape P every 4 weeks.

 

PANACUR (6-8 week intervals)

Start on March 31st with double dose Pyratape P, following at 6 week intervals with Panacur on May 14th, June 25th, August 6th, and dosing with double dose Pyratape P again on the 17th September.

For young stock start the first dose of Panacur 4 weeks after double Pyratape P.

 

IVERMECTIN (Panomec, Vectan or Eqvalan at 8-10 week intervals)

Starting on March 31st with double dose Pyratape P, following at a 6 week interval on May 12th with Panomec or Eqvalan, repeated 8 weeks later on July 7th and followed 10 weeks later on September 15th with double dose Pyratape P.

 

EQUEST (12 week intervals)

Dose initially on March 31st with double dose Pyratape P, following 4 weeks later on April 28th with Equest, and again 12 weeks later on July 21st. 10 weeks later on September 30th end with double dose Pyratape P.

The interval between July and September is shortened to fit in with the 6 month interval for the tapeworm dose.
