This subject comes up from time to time as we get more new folks on the list.
Many of us have seen endurance horses develop a rare type of colic called
anterior enteritis in which the small intestine literally shuts down, and it
almost always seems to occur in horses on Strongid C, the daily wormer.  Other
endurance horses on it have developed serious anemias which have resolved when
they were taken off of it--again, serious anemia is a pretty unusual problem
in our horses.  Since it also doesn't appear that a very high percentage of
endurance horses are on this medication, the correlation seems pretty
suspicious.  I don't recommend the product for endurance horses at all, and in
fact, strongly discourage its use in endurance horses.  I will hasten to add
that it is a very good product for controlling worms in growing youngsters,
and seems to be an invaluable tool in crowded situations during weaning, etc.,
and that I have never seen problems in any other class of horses other than
endurance horses with the product.  There should be some more posts on this
subject in the archives.
