I am requesting some assistance in developing an effective
worming program. The archives (some recent and some dated
posts) include several 8 week rotations of various classes/brands of
wormers, annual rotation with in classes (one class per
year), Spring/Fall rotation of Strongid 1st month and Ivermectin the
2nd month, some included pasture management practices, but most did not.
many rotations shared consistency in two methods: Ivermectin for
control of bots after a killing frost and Spring/Fall or at least Fall
Fenbendazole purge (most stated Panacur, but at least one Safe Guard) for
controlling tape worm and encysted small strongles. Several posts
suggested single dose panacur before the 5 day double dose purge to reduce the
risk of colic in horses with heavy parasite load. More than one post
cautioned the use of Quest. Panacur suspension and Ivomec injectable
were suggested as cost control measures.
I know individual circumstances influence the effectiveness of any
worming schedule, so here are a few details. I pasture three horses and
two ponies on 25 acres in North Central WV. Spring pasture is usually
lush in April and a light to heavy frost usually hits near mid October.
My horses are on turn out 24/7 except morning and evening feedings
and during very extreme winter weather. Based upon grass growth
patterns, my horses don't seem to graze areas where they drop manure. We
drag the pasture and brush hog twice in most years, but pasture rotation isn't
practical due to terrain and property lines. I am considering the
October: fenbendazole purge using Panacur suspension
November: ivermectin using Ivomec injectable
April: fenbendazole purge
Does this schedule seem adequate without unnecessarily stressing my
companions? Are Panacur suspension and Ivomec injectable still
recommended for use in horses? If so, what is the dosage (single and
double)? Any other comments/recommendations are welcome - especially
from our vets and nutrition experts.
Thanks for your suggestions,
