I might become a first time horse owner this week. My boarding barn requires a bi-monthly de-worming but I'm not sure what give?

I know you should use a Ivermectin as a base but it doesn't protect against all parasites, correct? Could I give her a ivermectin based de-wormer once a month and then another de-wormer 2 weeks later?

I'm a totally idiot to this as you can see. *Sits in the corner with a dunce hat.*

She is a 5 yo, TB, mare is that is important in any way. They get turned out all day on pasture and are in at night.

What do you guys give your horses?

If your barn has a schedule then that means they have specific types of wormers they want you to use. You don't have to figure out anything past that, just ask what one to use. And no, you do not always use ivermectin as a base.

Bi-monthly means every other month, so why would you give her an ivermectin once a month than another two weeks later? That is overkill and will result in parasites that are resistant.

Sorry- brain fart! You can see I'm pretty nervous about all this. :P

I'll ask a fellow boarder about it. Thanks!

Welcome to the Forum, Remember Me! I am in Virginia too and do rotational worming. The schedule that we are on is:
January - Pyrantel Pamoate
March - Benzimidazole - SafeGuard
May - Ivermictin
July - Pyrantel Pamoate
September - Benzimidazole - Safeguard
November - Ivermictin

No more "total idiot" talk. Actually, you are the total opposite. You are asking questions and admitting that you don't know. You are open to learning and that makes you smart!!

Thanks, Rather Be Riding. I'm just worried about getting my first horse and if I'll even get her. I've already had two horses fail the vet check, but because she seems so promising, near perfect confirmation and no noticeable movement flaws I'm just worried it will be something uncommon that will make her unfit for me.

Also I've noticed if you play it dumb on here you get more replies. Haha! I've never really gotten this close to horse ownership, never even full leased, but if she passes we bring her to the boarding barn the same afternoon. So I've wormed a horse once but I've never had to make up the plan and so forth.

Thanks for sharing your schedule! :)

But thing is if you are boarding and they have a schedule you do not make up the plan. They list what you are deworming with and when and then you go and buy that dewormer. Most barns will not let you do your own schedule with the exception that if your horse is on a daily dewormer then it's different.

The only thing to really be aware of is if they do the deworming or if each owner is expected too. At my current barn the owner of the horse buys the dewormer and puts the horses name on it and leaves it on the table, the barn owner then deworms all the horses so she knows they have all been done. Some barns expect the horse owner to do it.

The lease for the boarding barn says it requires the horse to be wormed 3 times by a vet and 3 times by owner.

Along with your new horse, you need a new horse Vet. Take your Vet's advice. It used to be that everyone rotated wormers. I still do that bc some parasites resist certain worming chemicals. Now, a lot of Vet's take a fecal sample to determine if your horse is a high or low parasite carrier and then suggests wormers and a rotation cycle.
My advice is to buy a tube of Zymectrin and administer when your horse gets home bc it's just like giving a tetanus antitoxin shot after an injury, just to be sure. Ivermectrin has been coming to the market in cheap wormers that are largely ineffective. You'll pay $7--up for a decent tube (up to 1,200 lbs). Ivermectrin was the 1980's wonder drug for horses. It is now used for other animals and humans, and the tube is paste with 1.87% (0.0187) of the drug in the paste.
In the Fall you will want to use Quest, which contains praziquantel to kill tapeworms. Your Vet will also give yearly shots which includes Tetanus (Toxoid), and specific to your area of the country, which may include Rhino, Eastern/Western Sleeping Sickness, Potomac Fever, and my Vet gave Rabies last year.
Read the instructions for worming. Pryrantal Paomate, Fenbendazole, Oxibendazole (I think some wormers still use this drug), will tell you when to re-worm. Most cover for 2 months, Ivermectrin works for 3 months, Praziquantel (developed here in Champaign-Urbana at the University of Illinois!) covers for 4 months.
Your Vet's input is SOOOOO important. Sometimes you will need to worm all 12 months, maybe your Vet will suggest not bothering with the winter months, but housing and worm egg access can aggravate your horse's parasite load, which is never zero.
Your Vet can also tell you if feeding daily worming pellets is worth the cost, too.

Once we decide on a regular vet I'll ask them about it. I suppose just using a Ivermectrin is okay until then? Anyone suggest any brands?

Does the present owner have info on the horse's past schedule for deworming and vaccinations? I never want to bring in a new horse without it being current on both. A fecal is a good idea especially if the horse will be turned out with others. With a fecal you will know if there are parasites and what to administer for them.
A new horse is exciting!!!! Keep us posted.
