It’s time to have a frank discussion about deworming.

Yes rotational deworming is ineffective and has created a lot of resistance to commercial deworming products.

HOWEVER

Horses with negative f***l egg counts ABSOLUTELY still need to be dewormed and here is why. We do NOT see bot eggs on f***l egg count, we rarely see tapeworm eggs on f***l egg counts, we rarely see threadworm eggs on f***l egg count and ALL are a problem for horses regardless of any other factors. They are infected with bots and tapeworms and sometimes threadworms even if they have a negative f***l egg count.

ADULT HORSES: At a MINIMUM even adult horses who are negative or low parasite shedders should be dewormed every 6 months with either ivermectin or moxidectin in combination with praziquantel. There are ONLY three commercially available products that contain those ingredients: Equimax™, Zimectrin Gold ™ or Quest Plus™. And these are the only dewormers that will work against those silent parasite infections as well as infections with strongyles (which are the primary parasite infection that we see in adult horses). Horses that are moderate or high shedders likely need additional deworming – but ONLY with products effective against the parasites they battle – and you should definitely talk to your veterinarian about how to properly manage them.

FOALS & Up to 2 Years Old: Foals (until they are two years old) need to be dewormed very aggressively against roundworms (ascarids) which are the most common parasite infecting young horses and if improperly managed can - and unfortunately far too often does - result in death. The anti-parasiticide that is effective against roundworms is fenbendazole and only in double doses. All foals should be dewormed once a month with a double weight dose of either of the two commercially available fenbendazole dewormers (Panacur™ or Safe-guard™). At the ages of 6, 12, 18, and 24 months foals should interrupt their regular deworming protocol for a single weight dose of Equimax™ or Zimectrin Gold™. Once horses reach the age of 2 years old they need to be dewormed as adult horses and have routine f***l egg counts. Definitely talk to your veterinarian about how to properly deworm your foal. If your foal is over one month old and has not yet begun a deworming regimen or deworming has been sporadic, talk to your veterinarian before you deworm them to develop an appropriate plan.

NOTE: moxidectin products (Quest™ and Quest Plus™) are metabolized in fat and therefore SHOULD NOT be used in very young, very old, nor very thin horses.
