Power-Dose Rotational Deworming

Our 36-year-old gelding continued to lose weight despite special feed, steroid shots and deworming. By late spring he was morbidly thin and still carried a heavy winter hair coat...

	Rotational Deworming Why Deworming Matters All horses develop parasites in their digestive systems. But, by administering a systematic, seasonal deworming program, these harmful parasites can be controlled. Experts agree that you should deworm six times a year, rotating different compounds (such as ivermectin, fenbendazole and pyrantel pamoate) based on seasonal parasite prevalence. Certain compounds combat specific parasites more effectively than others. But, when parasites are repeatedly exposed to the same compounds, they can develop resistances. Only correct rotation discourages resistance build-up and ensures optimum protection of the horse. Best scientific practice recommends deworming every 60 days, rotating among the three main chemical classes of compounds available (ivermectin, fenbendazole and pyrantel pamoate) to combat the parasites that are prevalent in that season.
	How To Get Rotation Right Your horse’s health is important to you and to Intervet, the makers of Safe-Guard®. We know parasite infection may represent the biggest health risk to your horse, but with the right program, it's easy to control. That's why we have developed an easy-to-use Rotational Deworming Barn Chart that you can post in your Barn, and know exactly when to deworm, and what type of dewormer you should be using every 60 days in order to simplify the process of rotational deworming and to Get Rotation Right!

	To use the Barn Chart, simply plan your deworming calendar to align with the seasons in your local area, and then for each Rotation period (1-6), deworm your horse by using one of the products listed for that rotational period. A sample deworming calendar for Missouri might look like this: Rotation 1. "Deep Freeze" = January. Use a Rotation 1 product with Fenbendazole, such as Safe-Guard for general parasite control and removal of all stages of encysted small strongyles. Rotation 2. "Past Thaw" = March. Use a Rotation 2 product, with ivermectin or moxidectin (with or without praziquantel) for general parasite control, and removal of bots and tapeworms. Rotation 3. "Grazing Season" = May. Use a Rotation 3 product, with pyrantel pamoate for general parasite control. Rotation 4. "Grazing Season" = July. Use a Rotation 4 product with Fenbendazole, such as Safe-Guard for general parasite control. Rotation 5. "First Freeze" = September. Use a Rotation 5 product with Ivermectin or Moxidectin (with or without praziquantel), for general parasite control and removal of bots and tapeworms. Rotation 6. "First Freeze" = November. Use a Rotation 6 product with pyrantel pamoate for general parasite control. It's easy! Now, request your own Rotational Deworming Chart and never worry again about how to Get Rotation Right!
