I was at a ride this weekend. Yes we are starting our season down here in
FL - yea. I asked the ride vet about Quest and his comments were "I sure
would not change a worming program based on this product." He went on to
say that the best way to kill tapes is Strongid P - probably a double dose,
or Strongid C - daily worming. He also said there had been a lot of
evidence that foals given Strongid C had much less problems with "the
snots". The theory is that many respiratory problems in foals is caused by
migrating larva. Many of the racing quarter horse breeders are also
reporting that horses put on Strongid C as a foal are must less likely to
be bleeders when they reach racing age.

The last tidbit was that many people now believe you can get the same
protection by giving Strongid C every third day.
