Here you will find all things worming.
This is a project I had to do for part of my Master’s course. It is a very detailed Cyathostomin (small Strongyle) lifecycle all based around an image of my very woolly horse, Sunny. It contains a lot of science-speak, but if you are curious to look at the lifecycle of this worm and its implications at a deeper level, then this is the poster for you. The above thumbnail is a selected portion of the detailed poster. Download now…
The NSW Department of Primary Industries is happy for their resources to be made available free of charge as long as they are acknowledged for it. I love their poster and I refer to it ALL the time as it is impossible to remember all the different brand names, active ingredients, what product is good for what horse parasite, etc. Print it out as an A3 poster, laminate it and stick it on the wall of your tack room so you can easily refer to it and leave out all the guess work.

Do I Call the Vet?
Dr Richard H. Chapman, BVSc, has published his long-awaited book – Do I Call the Vet? and what to do in the meantime. In his book Dr Chapman provides a treasury of information, tips, first aid techniques and – perhaps most importantly – reassurance. Dr Chapman can himself perhaps be reassured his many valued clients will now be able to stop reminding him about it!

Refugia are equine Cyathostomins that are NOT resistant to chemical anthelmintics. They are a crucial ‘antidote’ to resistant worms but they are becoming rarer throughout the world. Here is a short article that explains refugia…
Did you know that there are several nematodes that affect horses to varying degrees? The most pathogenic of these are the large Strongyle (S. vulgaris) and the foal roundworm or ascarid (Parascaris equorum). But this one, the Cyathostomin, is also of great concern to us as horse owners because they are becoming resistant to all of our available anthelmintics and no more anthelmintics are coming on to the market. This info-sheet gives you a bit of information about Cyathostomins – they are truly remarkable in their adaptations to our horses to ensure their survival.
This booklet reveals the future of parasitic worm management in our horses until a bettert strategy comes along in the future. It discusses the hows and whys of moving from routine deworming every 6 or 12 weeks, to deworming based on the evidence of faecal egg counts. Clicking the above link with take you out of this website and onto the booklet’s secure host website. We hope you will share the booklet amongst your horse-owning friends and feel free to download a PDF version to read when you have time. We hope you like it!
Yes, it does seem odd – or does it? This Info-sheet explains why worms can ‘hide’ inside our horses at certain times. Read the full article.
Momentum towards evidence-based worming is gathering speed, if our increasing contact with horse agistors is any guide. So we have put together a two page Infosheet which we hope will provide an easy-to-understand (and execute) strategy for undertaking the first faecal egg count (FEC) benchmark exercise for the property. We also include a paragraph on current best practice for introducing new horses to agistment properties as a way of preventing accidental introduction of resistant strongyles to the property.

In this Infosheet we have put together a few dot-points in managing horse herds in a way that can not only prevent the accidental introduction of resistant parasitic strongyle worms, but how to keep worm resistance to anthelmintics at bay. We hope that readers will find this to be a useful tool to add to their current integrated pasture management regime on their properties. Read more…
In this one-page info-sheet you will see at a glance what worming requirements are best for mares in foal, foals, yearlings and mature horses. Don’t take a chance with giving the foal the wrong treatment! Read more…
This resource is in table format, it provides a summary of each common gastro-intestinal horse parasite, its life-cycle, transmission, migration, site of predilection, pre-patent period, egg characteristics, identification through testing and other useful information. All in a handy, one-page format. Download it now…
Have you balked at doing your own FECs because of the cost of the equipment – especially the purchase of a microscope? You might be surprised at how quickly you will recoup your initial outlay or establishment costs. This cost comparison is based on a hypothetical herd of 5 horses. The more horses you have, the quicker you will be in front! Importantly, it will put you in total control of Strongyle worm management for your property. Here it is…
Tools & Forms
It’s easy to be tempted to purchase a cheap microscope, but when it arrives you might find you can’t move the slide around the stage to count the eggs! This one-pager will help you choose the right microscope from the beginning.
A tried and true ‘recipe’ that we use here at Evidence Based Worming.
Avoid an unnecessary or embarrassing incident at Australia Post. Packing the sample correctly to send away for FEC testing will ensure that your horse poo sample will not escape and end up on Australia Post’s sorting tables with the staff heading for the hills! We recommended this cheap, lidded container as it prevents escape of an odour that only horse lovers find delightful! This tool shows how to do it in just 4 simple steps.
Please complete one of these for each horse for which you are sending a sample. It helps us to look out for specific egg types (eg, if the horse is a youngster we will be on the hunt for roundworm eggs). We also use the sheets as a confidential record so, if you lose your records we are here to back you up.
Moving away from routine worming towards worming based on evidence can result in total confusion. We recognise this and have prepared a one page poster that hopefully clarifies what to do and when on a season by season basis, and when out-of-season warm, wet conditions help the grass to grow. Worms can’t get around very easily unless the conditions are right!. You might want to print it as an A3 poster, laminate it and stick it on your tack room wall for easy reference.
This one-page resource explains the easy formula necessary to undertake a FECRT to determine whether your horse might have worms that are resistant to a particular worming treatment (anthelmintic). It’s easy to do and will provide you with some certainty about what might be going on!
It is not generally well known that under-dosing with anthelmintic treatments is a key contributor to Resistance in our horses’ worm populations. Know your horse’s weight and do not underdose! This one-page tool provides 4 handy ways to estimate your horse’s weight.
This is a great tool if you want to know how the calibrated equipment used in our kits has been designed to arrive at the number of eggs per gram of horse manure, the number that provides the basis of whether or not it is necessary to treat a horse with anthelmintics.
