Worming update.
Our previous worming posts have attracted lots of discussion so here is a New year's refresher on our current guidelines.
We are not currently running faecal worm egg count samples as the weather has been cold recently meaning worms are unlikely to be reproducing and therefore looking for eggs is not a reliable form of checking for parasite burden.
In recent years we have recommended treating once a year in January with moxidectin to kill encysted larvae. However updated guidelines suggest that this is not necessary. Reducing our unnecessary use of moxidectin will help prevent resistance build up in worm populations and help keep it as an effective treatment for the future. Instead of blanket treatments, guidelines show that we can instead perform a risk assessment on individual animals taking into account age of the horse, whether their worm egg counts have been low through the rest of the year, whether faeces are removed regularly off the pasture and whether there is a lot of change in other animals they are turned out with, particularly young (< 5 years old) or more senior (>25 years ).
For our health club horses instead of providing one moxidectin wormer per year, for those that are deemed low risk and don't require a moxidectin treatment, we will be substituting this with an equisal tapeworm saliva test to check for tapeworms. This is something we can't check with our normal faecal worm egg count.
For horses in the health club we are currently reviewing all worm egg count results from last year and will be contacting owners individually to complete a risk assessment and let them know when their tailor made annual worming box is ready to collect.
We are also putting together a talk on worming to be presented at yards to help everyone understand new guidelines and best practice for your horse. If you would like to be added to the list of yards who would be interested in having one of our vets come to talk with you please comment below or ring the office so we can add you to the list.
