DEWORMING

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.

ROTATIONAL DEWORMING SCHEDULE

 Jan: Paste deworm with Anthelcide EQ (oxibendazole)

 Mar: Paste deworm with Strongid (pyrantel pamoate)

 May: Paste deworm with Quest Plus (moxidectin and praziquantel) or
           Equimax (ivermectin and praziquantel)

 July: Paste deworm with Anthelcide

 Sept: Paste deworm with Strongid

 Nov: Paste deworm with Quest or Equimax or Tube deworm

An alternative deworming program consists of feeding the continuous daily dewormer (Strongid C) and using a boticide (Equimax) after a killing frost in the fall and again in the spring.

Pfizer, the makers of Strongid C, has developed the PreventiCare Program. There is a $50 charge per horse. While on this program, Pfizer will pay the first $5,000 of a colic surgery if your horse should ever need it. There are a few requirements to meet in order to qualify for this program. Along with feeding your horse Strongid C daily and deworming with Equimax,  in the fall and spring, you must have a yearly physical exam, dental exam, and nutritional consult performed on your horse. All yearly vaccinations must be given by your participating veterinarian or purchased from that veterinarian.
