Rotating wormers won't get the worms that are likely to produce a huge glut of worms suddenly in the intestines -- namely, the encysted small strongyles(http://www.power-dose.com/faq.asp). I took a horse I was selling over to the clinic for his pre-purchase. I'd wormed him with Ivermectin a few days before, but the fecal showed small strongyles (but no other worm species). The vet explained that the encysted strongyles are constantly emerging from their cysts and contaminating the manure. The older the horse the greater the load of encysted strongyles it is likely to have. He recommended a Panacur Pwer Pack worming, which we did, and the horse quickly looked brighter, started gaining weight, etc. Lynn Kinsky, Santa Ynez, CA http://www.silcom.com/~lkinsky/ http://www.dslextreme.com/~napha/JoyOfRiding/index.htm
