Worming Schedule

Where are you located, and what worming schedule are your horses on?

I am in Colorado, and this is the schedule I put together for my filly:

January: Moxidectin

March: Fenbendazole

May: Ivermectin

July: Pyrantel Pamoate

September: Fenbendazole

November: Ivermectin

Hmmmm I have always heard the schedule you are supposed to stick to is once every 3 months?? My guy gets done that way and I use the paste with him by rotating with a different brand each time.

Deworming programs should be based upon risk factors such as horse age, inherit resistance of each horse to parasites, management practices such as pasture or stall care, other horses pastured with the horse and weather conditions where the horse is kept.

For Colorado, it looks like your deworming schedule is sorta backwards. Your horse is more likely to pick up parasites during your summer when weather is moderate so you should focus more on parasite control during that season. The winter months when you are likley dealing with snow/ice and your horse is stalled and/or on hay rather than pasture is when you will have less risk of parasite reinfection. In really cold climates where horses are on hay and no pasture in winter, it may even be reasonable to discontinue deworming during the winter. You also appear to be deworming at 8 week intervals which isn't really an appropriate plan. You should be deworming based upon fecal egg counts or in situations where there is high risk of reinfection and a horse that is susceptible based upon egg reappearance periods for the drugs you are using to help minimize recontamination of the pasture. Only 1 drug has an 8 week egg reappearance period--ivermectin. There is no need to deworm for at least 12 weeks after using moxidectin (and using fenbendazole or pyrantel earlier than that really is likely to be ineffective as you will likely not have many adult parasites and that is what those drugs kill).

I would recommend that you talk to your vet about setting up a strategic deworming program based upon your horse and his situation. You will likely save money and help slow the developement of drug resistance in parasites while still keeping your horse's parasite load low.

Check out this webinar available through "The Horse Magazine" The Horse: Videos (it takes a while to watch) or get a copy of their Jan. 2009 magazine (current issue) to learn more about why strategic deworming is so important.

Michigan and I stick to the chard Safeguard put out. I "powerdose" (5 day, double dose) all new horses and every January - then stick to the rotation every six weeks.

I live In the ACT, Australia. I got to admit, we are a bit lax when it comes to worming. We try to do it every 3 months or so, but tend to do ti when we remember, and I just buy a brand I didn't buy last time. However we only have three horses on the farm, and their paddocks are rotated regularly, so we have never had any worm problems.
