My horse is boarded on a contaminated pasture. Unfortunately daily pelleted dewormer is not available in Canada. What dewormer regiment would you recommend in my case?

Dianna, can you tell me more about the nature of the parasite contamination and whether this is an ongoing problem or a past problem that has been corrected.

Hi, A horse at the barn was diagnosed with small strongyles. Apparently this is a problem in the lower mainland (the southern coast of BC). I suspect that this is an ongoing problem as we are not on a common deworming schedule. We are encouraged to worm at the same time but don't use the same wormer. For this reason I wanted to use the daily wormer but it won't clear customs if I order it from the states. Some types of paste dewormer that are not available here can be ordered from the states. (such as Invermectin gold, etc.) The pelleted type can't get through.

Got it and how many horses are there on how many acres and what is turn out like. Also is there any manure processing?

There are only about 8 horses at the moment but this number fluctuates and has been as high as 20. There are about 20 acres of pasture and no manure processing.

Well potentially this could be a very heavily contaminated pasture and you really should consider moving your horses to a better situation. As long as your horses remain disease free and don't seem to be particularly food inefficient and the pasture stocking rate at less than 2 horses per acre I would stick with the deworming programs as outlined in our Schedule's article. If any of the above caveats our broken you should consider decreasing the time between deworming from 75% to 50% of the recommendations.
I would also try this: put up a chart with all the horses names listed on the left and that horses owners fill in when they deworm giving the date and product used. First it helps you understand the potential for heavily contaminated pastures and it might serve to stimulate more regular deworming by the horse owners.

Thank you for your help. My horse is very food efficient and energetic at the moment. I just wormed her with invermectin when I heard about the strongyle problem. Even though the schedule in the article doesn't call for invermectin with pranquazel(sp?) until Nov., I wonder if I should do that next. I would move her but the turnout is so big and it's hard to find barns with a proper worming program as there's always someone out of step. I will try the list ASAP.

If you have not ever dewormed for tapes I would go ahead and do it my next deworming, an extra praziquantel won't hurt a thing.

I also keep my horse on a contaminated pasture. Let me tell you a little bit of his history. I bought my 5 yo TB gelding from a hunter barn in Texas in 12/2004. He had minimal turnout. He was basically stalled 24/7. I moved him to a barn in Shreveport, LA, where he is now turned out 24/7, except at grain feeding times. He was on a deworming program in Tx. The barn manager put him on her deworming program in Shreveport. All the horses are dewormed at the same time with the same medication. The pasture is totally unmanaged. The manure is not harrowed or picked up. There are 11 geldings on about 20 acres. My horse started to lose weight. We had an equine dentist do his teeth, I added a weight supplement. Nothing worked. We took him to the vet. He did not know what was wrong with him. He empirically treated him with the Panacur Power-Pak. We ended up taking him to LSU-Equine Vet Center in Baton Rouge. After many tests, he was diagnosed with malabsorption syndrome of unknown origin. Their differential diagnosis included: worm infestation of strongyles, lymphosarcoma, or a colitis. Without further costly testing, a definitive cause of his malabsorption could not be determined. We decided to treat him empirically for each individual possible diagnosis, starting with the strongyle infestation. He was again given Panacur Power-Pak 30 days after his first dose, then 4 weeks later was given Quest Plus because his fecal showed 2x eggs. Since that time, he has gained all his weight back, plus some. His coat is gorgeous with dapples and everything. Therefore, I can assume that his malabsorption was from a strongyle infestation. My question to you is this. How should I deworm this horse? No other horse at this facility has a problem with worms. Obviously, my horse is a hard-keeper and needs extra care. Please help me! |

Amy what does the current deworming program consist of?

DR. O,
My horse's deworming schedule is as follows:
Jan: Strongid
March: Combo Care
May: Anthelcide EQ
Then it repeats for the remainder of the year. He also has now started having some loose stools. I had a fecal done, and it had some large strongyles, but not in every field.
Thanks,
Amy |

Though your schedule may look aggressive it suffers from a basic problem. The Combo-care knocks back the strongyles aggressively so there is about 3 months before adults are produced but the anthelcide and Strongid only kill adults allowing the larvae to still develop and produce eggs. In your high exposure environment this is not enough to control either large or small strongyles.
You should be at least following our recommended schedule and if the other horses are not adequately dewormed consider doubling the recommended frequency or even moving your horse.

Dr. O,
Thanks so much for your help. I have ordered a daily dewormer, and also the ivermectin plus praziquantel to be given one month after starting daily dewormer.
