<< I once asked an Australian
dressage instructor who was visiting Calif. about their worming programs.
Ivermectin has been available in Australia many years longer than in the
U.S. At the time, she said they have been using it exclusively with no
rotation for many years with no problems. >>
Glad to read this!!! I too, have been using Ivermectin with no rotation for
many years--with no problems. Started worrying here after reading all the
"rotate 2X per year with double Strongid" posts.
