Worming and resistances in S.E. PA?

[Reddfox]

Sorry for another worming thread - I did several searches on schedules and resistances, but I'm moving to a new barn and my old barn handled all the worming. I want to be more knowledgeable about S.E. PA specifically. I'm also curious about what fellow Pennsylvanian's are doing as far as worming schedules and what resistances are in PA that people know about.

My old barn uses Panacur in the rotation - and all that I'm reading is saying that there is widespread resistance to it. SO, I'm trying to get a game plan as far as schedule and what to use. I'll also talk to my vet of course and I'll be having a fecal count done - but my appointment isn't for another week and a half and my OCD self wants some answers to chew over now:lol:.

TIA!

Pennsylvania is a really big state. You might want to focus on what is going on in your local barns. And we'd have no way of knowing that.

What makes you think you have a worm problem the de-wormers aren't getting?

Before I accepted "rumors" of dewormer ineffectiveness due resistant strains I'd contact my local Extension Office and get in touch with the PA Extension Equine Specialist. Or maybe contact the PA State Vet. and ask if there is a resistance problem. If you find out that there is you'll likely get good information from either source.

If you're not against using Quest, I would use it every other year for encysted strongyles. I don't know if you will be able to find out about local resistance, encysted strongyles don't show up in a fecal test.

Thank you! I will try to contact these groups to ask. I was simply looking for information because I was doing a lot of reading that there are Panacur resistances.

I'm not assuming that the wormers aren't working - I am going to be doing a fecal count to find out where my mare is at.

I just was hoping for some information and some conversation starters for my vet when she comes. I'll ask around at some local barns and see what they're doing as well.

Sorry, I didn't mean to come across as sounding suspicious or as having a knee-jerk reaction to what I was reading - just hoping some fellow S.E PA COTHers would share some info.:winkgrin:

You just missed a great presentation by Dr. Pugh last week. Unionville vet clinic sponsored it. You could call and see if they are planning another session.

He said that in the SE, worms have developed resistance to many classes of dewormers. He also said he does not know about worm resistance in this particular area.

In addition to checking your local resources for information about worms in your area, he recommended deworming on the day you do a fecal, then check again in 14 days to see if the eggs per gram has decreased. If not, one can assume that the dewormer was ineffective for that horse.

Just had this conversation with my vet... using ivermectin all year except for after the 1st frost using a wormer that will get tapes. Panacur not the kill-all that it used to be. My vet doesn't even do it on their horses!

Except, ivermectin will not get encysted strongyles. You need a Panacur PowerPak (which is showing some resistance) or Quest. Just had a boarder horse who had never been adequately wormed for encysted strongyles that kept colicking mildly (vet said he was progressing to impaction colic). Turned out to be encysted strongyles. He's fine now, after a Quest deworming.

If you want to know for sure, for your horse at this time, you'll need to run a few fecals. The first will tell you what, if anything, is present. If you get a low/no count, run another in a month as you can get a false negative.

If/when you have something show up, use the appropriate chemical, and re-test in 2 weeks. That will tell you if the chemical is effective for the load your horse has.

In maryland our vet is asking us to do fecals and worm accordingly...now if i can convince everyone at the barn to do it....(selfcare facilty..urg)

Same here in my little corner of SE PA.

As should every vet in every part of the world ;)

Excellent advice JB. That is pretty much is what Dr. Pugh advised. There were some other things, but I'd rather not put words in his mouth, as he can speak very well for himself. :lol: The guy was hilarious, but I sure wouldn't want to get into an argument with him. ;)
