We're going to Camp Atterbury, IN in the next couple of months and I'll be boarding again. I've been told there's a horse park at Atterbury but I can't find any information online.
Very nice - we've had reason to go up to Atterbury a couple of times since we PCSd out here (we came out on recruiting duty, so we aren't actually near any base, but Atterbury and Knox are fairly handy/close). I think you are thinking of the Hoosier Horse Park - searching by name should give you tons of info.

Here is one link I have found:

Yeh there's no real base there it's just reserves. It's going to be a culture shock for me not to have a commissary, PX or base hospital. We rarely buy groceries on the economy so looks like we'll be doing trips to Knox for that.

I found a property today that has almost 40 acres so fingers and toes crossed we can get that place. It would make life a lot easier.

Best of luck to you on the property!! We went up there for IDs as they were much more accomodating than the reserve center in Louisville and less busy than the pass/ID at Knox.
It isn't too bad living w/out the base stuff handy - prices really aren't that different once you factor in making the trip to Knox, but I still find an excuse to go down that way a few times a year.

For those of you who are deworming every other month, you are really over doing it. 2-4 times a year is really all that is needed in the US, with most adult horses only needing to be dewormed twice a year. You really need to deworm based upon the specifics of your situation and your horse.

BarrelRacer_Up, you would show negative fecals no matter when you collected samples with your deworming program but you are really dosing way more than necessary. You shouldn't redose ANYTHING for at least 12 weeks after using Quest (moxidectin).

I'm copying my other post here to make it easier for everyone to find.

The newest recommendations as of June 2009:

For 40 years now, veterinarians have recommended that horses be dewormed every 8 weeks all year round and rotation of dewormers has been recommended for nearly that long. This is considered by many vets and horse owners to be “the recipe” for adequate and appropriate deworming of horses. However when you look at the research that has been done in the last 15 years you really have to question this practice. “’The recipe’ no longer represents an acceptable program for strongyle control” according to Dr. Craig R. Reinemayer, DVM, PhD of East Tennessee Clinical Research, Inc during a webinar presented via www.thehorse.com. This means that deworming recommendations for adult horses need to be reconsidered because strongyles are the only significant nematode pathogen of mature horses. Continuing to use the same old deworming program will likely lead to heavily parasitized horses and further drug resistance. Instead, each horse and each situation should be evaluated to determine the reinfection rates and an appropriate deworming program for the individual.

It's now known that all adult horses living in the same situation do not necessarily need to be dewormed on the same schedule. 50% of horses in a herd will control parasite loads on their own due to natural resistance. Only about 20-30% of horses carry heavy parasite loads.
Thus each horse should be dewormed based upon an understanding of his own personal resistance to parasites. The best recommendation is now 2-4 dewormings a year based upon knowing which horses carry lots of parasites and which tend to carry little parasite load.

Rotational deworming is no longer an adequate or appropriate deworming program for adult horses. There are too many issues with strongyles developing resistance to 2 of the 4 most commonly used dewormers on the market---fenbendazole (more than 90% of areas tested have resistant strongyles) and pyrantel (around 1/2 of areas tested have strongyles resistant to this drug). And resistance is starting to be seen in strongyles to ivermectin---1st study showing it was done in KY in the last couple of years.

All adult horses in the continental US/Canada should be dewormed spring and fall with ivermectin/praziquantel or moxidectin/praziquantel. Other than those 2 standard dewormings, the rest of the deworming program should be based upon location and the horse's own resistance to parasites. The new recommendation is 2-4 dewormings per year based upon fecal egg counts used to determine the normal amount of egg shedding each horse does during the time of year when the weather in your area is most conducive to strongyle larva development and environmental survival. In the northern states in the US and in Canada, this means running a fecal egg count in the middle of summer (3 months after spring dosing if you used ivermectin or 4 months after spring dosing if you used ivermectin). In the southern US and Mexico you would be looking at testing in the middle of the winter (same time after spring deworming as listed above). Then based upon the number of eggs per gram of feces you can determine if you need more than the spring/fall dewormings and if so if you need 1 or 2 more dosings.

In the northern US and Canada, deworming should be discontinued during the winter months because the environmental conditions are not conducive to reinfection---that time of year has been proven to have extremely low reinfection rates. In the southern US and Mexico the opposit is true....deworming can be discontinued during the heat of summer because temps over 85 degrees lead to the infective strongyle larva dying quickly in the environment so the reinfection rates are lowest then.

For more detailed information check out the deworming webinar that was aired via The Horse magazine's website in April. Be prepared to sit for a while because it is an hour long presentation, but it's well worth the time. The veterinarian gives you all the information on strongyles and deworming in adult horses that you've always wanted to know and then some. It is a wonderful lecture. (And have plenty of paper and a pen.) http://www.thehorse.com/Video.aspx?vID=1…

I go by this chart --> Sample Paste Dewormer Rotation Schedule

I worm her every other month, going by the chart.
I know many vets say that horses shouldn't have to be wormed that often, but where my mare is boarded at they are constantly bringing new horses through from auctions, new boarders, etc. They also live on fairly small sand paddocks, which never seemed to be picked very often at all.

Even with a possibly high exposure your horse may not need to be dewormed that often. 50% of horses will control parasites with minimal chemical intervention. Plus with the your weather in the deep winter months you should need to deworm during that time anyway.

The deworming schedule you use is one of the worst because it has both benzimendazoles and pyrantel and it doesn't take into account the fact that moxidectin's egg reappearance period is 12 weeks meaning that there aren't significant adult parasites for 12 weeks after dosing. They have you dosing with an adulticide 8 weeks after using moxidectin--that's a complete waste. They also have you using a class of drug that is likely to be ineffective during the summer months which is when you have the highest parasite reinfection rates.

So while you are deworming every 2 months you are likely wasting your money for 3 out of 6 dewormings and doing a poor job of controlling parasites if your horse is one of those that does develope heavy parasite loads.

Is that a typo? If not, I'm confused. I am very interested in the new info........thank you for posting all of this.

No, that is not a typo. To get an indication of what type of egg shedding your horse normally does you need to collect a fecal sample a month after the egg reappearance period has passed for the last drug used and during the time of year when your reinfection rates are going to be highest due to conducive weather conditions for the parasites.

So if you are in the northern part of the US you would deworm early in spring with either ivermectin/praziquante or moxidectin/praziquantel. Then collect your fecal sample at the appropriate time and have a Fecal Egg Count done to see if your horse is a high, medium or low egg shedder. If you used ivermectin for the spring you would collect a sample 3 months later and if you used moxidectin for spring you would collect a sample 4 months later. This allows time for your horse to have picked up infective larva after your last deworming and for those larva to mature to egg laying.

That was my point - in the quote it only says ivermectin for both the 3 and 4 month -- I was confused but thinking they likely meant to use moxidectin on one or the other but wanted to be clear on which one.
