Loss of condition, poor performance, diarrhoea, anaemia and colic are just some of the many problems that worms can cause.

Avoiding these problems have traditionally relied on dosing with anthelmintics (wormers) but with resistance to these drugs and poor management practices worm problems are becoming more persistant.

Anthelmintic usage is still important but should now be used used after checking faecal (dung) samples for the level of worm infection present rather than just routinely dosing. This is more cost effective and provides accurate information as to the worm challenge. If there are no worms, there is no need to treat!

Frequency of treatment has to be tailored to each and every situation and it is important to consider grazing available, the number of horses grazing, the age of the horses and any anthelmintic resistance known in that area.

One of the most important and simple procedures to reduce worm challenge is to 'poo pick' that is to collect all dung each and every day!!

The ‘Senlac Tailored Worming Programme’ will help to keep your horse healthy from internal parasites
without using wormers indiscriminately. This will not only save you money but also reduce the resistance
to parasiticides of gut worms on your paddocks to the wormers you frequently use.

For a one off fee of £25 per horse per year, you will receive:

  • Up to 3 faecal worm egg counts per year; usually £37.20 (we suggest in the spring, the autumn and one other time in the year)
  • A worming programme specifically for your horse as advised by one of our vets
  • E-mail reminders as to when to bring the samples in*
  • 20% off of all equine wormers purchased in the practice


This offers a saving of up to £61 per year if worming was carried out three times a year and was not necessary!

To take advantage of this service, please contact the practice to register your interest, either by phone or e-mail, with your name and horse’s name.

*E-mail address required. Unfortunately we are unable to send out reminders by post.
