Deworming horses can greatly decrease the incidence of colic and is an important part of their preventative health care program. Researchers have found that colic can be significantly reduced by putting horses on the continuous daily dewormer (Strongid C) or by deworming every 60 days.

Because internal parasites develop resistance to medications, we recommend using a variety of different dewormers. When rotating dewormers, it is important to use ones that are not similar in chemistry. Fortunately several new deworming products have been developed, many of which are in a paste form and can be easily administered by mouth. Other medications are given in combination through a stomach tube.

It is essential to remember to use an ivermectin product or Quest Plus after the killing frost in the fall to kill stomach bots.
