A great way to reduce costs when worming multiple horses is to buy the liquid form of fenbendazole. It can be used as an individual worming, or it can be used like a "Panacur Purge".
It can be purchased from KV Vet at this link, or from Valley Vet Supply at this link. You can also buy it packaged in a five dose syringe pack for the purge worming. It costs a lot more that way!
I've been using the liquid form of fenbendazole for years and do at least one five day purge on my horses per year. I can purge worm three or four horses with one bottle and still have enough left for some individual wormings later. That cuts my cost down by about 75% of the cost of purchasing it packaged the other way. Click here to see the cost of purchasing it packaged for the purge.
