Strategy-T contains a unique combination of two worming compounds that act synergistically against the major worms of horses including the benzimidazole (BZ) resistant small strongyles and tapeworms.
Indications for Strategy-T
Broad-spectrum horse worming paste that is effective in treating all major worms in horses including:
- Large strongyles (Strongylus spp. Triodontophorus spp.)
- Small strongyles including benzimidazole resistant strains (Cyathostomum spp.,)
- Ascarids (Parascaris equorum) including abamectin, ivermectin and moxidectin resistant strains
- Pinworms (Oxyuris equi)
- Tapeworms (Anoplocephala perfoliata)
Each Strategy-T 35mL syringe contains:
9.1g Pyrantel Embonate
Dose at 1ml per 20kg bodyweight. Each weight marking on the plunger will deliver 5mL of paste, which is sufficient to treat 100kg body weight.
Each syringe treats a horse up to 700kg.
Can Strategy-T be Used in Mares?
Yes Strategy-T® can be used in mares at all stages of pregnancy. Pregnant mares should be treated as normal during their pregnancy taking care not to stress them during treatment. Mares should be wormed two weeks prior to their expected foaling date. Once a mare has foaled, the mare and foal should both be wormed starting from when the foal is six weeks old.
When should I start worming my foal?
Strategy-T is safe to use in young foals. Pregnant mares should be treated as normal during their pregnancy taking care not to stress them during treatment. Mares should be wormed two weeks prior to their expected foaling date. Once a mare has foaled the mare and foal should both be wormed starting from when the foal is six weeks old. Young horses need to be treated differently to older horses because they are at risk of mectin resistant ascarids.
Ascarids appear to be the worm developing resistance to mectins. Generally ascarids are not found in horses over two years of age as horses seem to develop a natural immunity to these worms as they mature. To protect young horses from potential mectin resistance, it is recommended that a combination product registered to treat mectin resistant ascarids, such as Equimax Elevation or Strategy-T, be used. Young horses should be wormed with Strategy-T in spring and summer and Equimax Elevation in autumn and winter from six weeks of age until they are two years old. At this stage they can be put on the Equimax/Strategy-T rotation.
Can I use Strategy-T in my stallion?
Strategy-T can be safely used in breeding stallions at any time without adversely affecting their fertility.
How often should I worm my horse?
How often horses are wormed depends on the property’s management system. It is ideal to use the minimum number of treatments possible in a year, as over-worming can lead to resistance. Depending on a number of factors, some horse owners will need to worm more often than others. Where there are large numbers of horses kept close together and/ or horses are frequently moving on and off a property, there will be a greater need for worm control. This is because these horses will be at the greatest risk of contamination. Horses in these situations, generally on studs or agistment properties, will need to be wormed every six to eight weeks. It may be possible, where there are low stocking densities, to worm horses less often. The use of paddock management procedures like manure removal, paddock rotation and grazing with other species will also help lower contamination pressure.
All horses should be wormed at least once every 3 months regardless of the conditions in which they are kept. All horses on a property should be wormed at the same time. New horses should be quarantined and wormed before coming onto the property. If you are unsure about what drenching interval is right for your situation please consult your vet or local Virbac area manager.
What is rotation and why should I be doing it?
It is important to “rotate” wormers by alternating from one compound to another. This should not be done every time you worm, but rather on a seasonal basis. In Australia, seasonal conditions are ideal for parasite growth during most of the year, particularly the warm wet months of spring and autumn. The lifecycle of different parasites mean that they may be more active at different times of the year.
When considering a rotational program, you must also ensure that you are actually changing the compounds that you are using. Many of the wormers on the market contain the same or similar active ingredients and switching the brand name or colour of the box may not mean you have actually changed the active you are using. There are two main families of active: the “mectin” or “ML” class those with names ending in “-ectin”, and the “BZ” class of active those ending in “-azole”. There are other classes of active ingredient, but they are less commonly used and are generally used in combination with other actives to target speciﬁc parasites.
To ensure the best seasonal worm treatment, it is recommended that a BZ-based wormer like Strategy-T is used in spring and summer, and a mectin-based wormer like Equimax is used in autumn and winter. You may also want to include a special treatment in early spring for encysted cyathostomes if these are a problem for your horse. Either fenbendazole* or moxidectin can be used under veterinary supervision.
Why is it important for me to accurately estimate my horses weight?
Most people underestimate a horse’s weight by as much as 20%. Underestimating a horse’s weight can lead to underdosing. Giving a horse less than the required dose of wormer can leave them at risk of worm-related disease as potentially worms will be left untreated within the horse. Underdosing can also encourage the development of resistance in your horses by exposing the worms to sub-lethal doses of wormer. It is therefore vitally important to correctly estimate your horses’ weight when deciding on the correct dose of wormer to give them. It is in fact preferable to give horses a slight overdose rather than an underdose.
There are several methods for finding out a horse’s weight, the most accurate obviously being a set of scales. As most horse owners to not have easy access to horse scales, there are several other methods that horse owners can use to get a good estimate of their horses’ weight. The use of the weight estimation formula will give a reasonably good estimation of most horses’ weight. The formula is:
Another method that can be used to estimate weight is by using one of the commercially available weight tapes. Unfortunately some of these tapes are far more accurate than others so it is a good idea to calibrate the tape using the formula first to check that it is measuring accurately. Weight tapes are also not suitable to use in immature horses as they have a different body composition to older animals.
Can I use Strategy-T on an animal other than a horse?
Strategy-T is registered for use in horses which means it may be safely used in horses. The use of this product in any other species would be considered “off label usage”. Products should not be used outside of their registered label claims without first consulting a veterinarian (if at all). Variation in metabolisms between different species mean that dose rates can vary quite widely. Some species may be far more sensitive than others making products dangerous or even potentially fatal to those animals. It is for this reason that “off label dosage” should only be conducted under the supervision of a veterinarian.
