Intestinal parasites, or worms, are present in low numbers in most horses. However, in larger numbers they cause damage to the gut itself along with other internal organs as these worms migrate.
Resistance to wormers (anthelmintics) is an ever increasing problem. Worms develop resistance to the treatments used to kill them faster than new wormers can be developed. For this reason it is important to reduce the use of wormers where possible and to use them correctly when needed.
Reducing Wormer Usage
- Poo-picking fields very regularly is very effective in reducing worm egg numbers.
- Use worm eggs counts on dropping samples throughout the year to confirm whether a wormer is actually needed.
- Blood or saliva tests can be used to look for tapeworms.
- Don't over-graze fields.
- Old and young horses are more susceptible to worms as their immunity to them is poorer.
- Try to have all horses that graze together on the same worming program.
Correct Wormer Usage
- Worm egg counts can tell you if you need to worm.
- Worm correctly for weight - do not under-dose.
- By using a program you can expose worms to fewer drugs and lessen their chances of becoming multi-drug resistant, compared to a "scatter gun" approach when you remember.
- Our worming programme is designed with this in mind from each year to the next.
- Worm strategically at different times of the year, using the most effective drug for the prevalent type of worm.
