encysted larvae, large redworm and pinworm. The other wormer is, Equest (Moxidectin) This treats roundworm, large and small redworm, bots, developing and encysted small redworms larvae.
Not all wormers are effective against the encysted small redworms and the only two to treat these are the ones above.
Please remember when using the Equest Moxidectin, not to overdose. Check the weight of your horse first. You can do this by using a weight tape for horses.
If this is the first time you are measuring your horse with a weight tape, please be careful because they can get spooked. Let them smell the tape and rub it on their body first and see how they react to the tape.
When you measure your horse try to do it at the same time of the day or you can get different measurements if you are keeping an eye on the weight.
Get your tape and start by wrapping it around your horse where the girth will sit. Then to go around the back of the legs and behind the withers. Bring the two ends of the tape together and pull tight and see what the weight reads.
Once you have wormed your horse try to keep the area clean of droppings.
It is best if possible to rest part of your grazing for at least five months of the year. This is how long it takes for the small redworm larvae to die. It does survive for this lengh of time in your field.
You can also do a worm count and see which worms are effecting your horse and in most cases we over worm horses. You can ask your vet to send you out a pack to do a worm count or there are lots of places on the internet that do the same and alot of the time it is cheaper. One thing you need to remember is that the encysted small redworms are currently dormant so they wouldn't show in an egg count. You do need to use one of the two wormers for your horse. Through the winter the small redworm larval stages bury into the gut wall. Read more on worms and the effect they have on your horse here. Worming chart here
If for any reason you are worried about worming your horse or not sure which wormer is best, then give your vet a call. Leave a message with the receptionist and the vet will get call you back and let you know.
Always keep the Equest Moxidectin away from dogs. It is very danerous to the dog if eaten!
