Horse Worming Regime at SimplyHorses Equine Vets

Here is an example of the ideal targeted worming regime we recommend at the clinic.

Note this is not suitable unless the yard (livery or private)  has a strict management and pasture control regime in place.

For more details give us a ring at the clinic.

Targeted Strategic Worming Regime:

March:  Faecal Worm Egg Count (FWEC) taken from every horse, those with levels over 200 eggs per gram are wormed

June: Faecal Worm Egg Count taken from every horse, those with levels over 200 eggs per gram are wormed

September:  Faecal Worm Egg Count taken from every horse, those with levels over 200 eggs per gram are wormed

October:  (Optional often combined with worming  in November) Double Dose of STRONGID P or Double Dose of PYRATAPE P or EQUIMAX for tapeworms (levels not detected on FWEC)

November:  EQUEST or PANACUR 5 day guard or EQUEST PRAMOX (if EQUEST PRAMOX no need to worm for tapeworms in October), this worming is to eradicate small encysted redworms (hibernating red worms).   Good regime for less intensive situations but hard to implement successfully in busy yards with high numbers entering and leaving the yard and high numbers rotating through paddocks:

Worming Your Horse: Do It Properly Ask Your Vet!

A recent Study shows no resistance to moxidectin – 04/06/2009

A European study to evaluate the efficacy of the key anthelmintic molecules in treating equine cyathostomins has confirmed that resistance is developing against all of them, with the exception of moxidectin.

The study focused specifically on the molecules fenbendazole, pyrantel, ivermectin and moxidectin.

Resistance to fenbendazole was highlighted as a particular issue with 80 per cent of the yards tested in the UK and Germany showing resistance. Resistance to pyrantel also proved to be increasingly prevalent while cases of ivermectin resistance were emerging.

A small redworm larva The Fort Dodge-sponsored study, the largest of its kind so far undertaken, took place during 2008 and was led by scientific teams from veterinary faculties in Italy and Germany. It was based on Faecal Egg Count Reduction Tests (FECRTs) of 1,704 horses at 102 yards in Italy, Germany and the UK. The calculation of FECR data was performed employing bootstrap analysis of group arithmetic means.

The study concluded that:

* The testing of fenbendazole in a total of 80 yards showed resistance present in more than 80 per cent of the UK and German yards and in 38 per cent of Italian yards;
* Pyrantel was tested in all 102 yards with resistance being found in 25 per cent of yards in all three countries;
* Resistance to ivermectin was significantly lower with resistance found in only one yard in Italy and two in the UK from a total of the 102 yards tested;
* No resistance to moxidectin was detected in any yard in any country;
* Multiple resistance to fenbendazole and pyrantel or ivermectin was identified in all three countries, with one yard in the UK found to have resistance to fenbendazole, pyrantel and ivermectin.
