Battling Resistance

Seems that Panacur and Strongid don't work anymore. Never knew until we tested.

No problems with worms BUT the horseflies are totally resistant to every spray I can find this year!

8/23/2010 1:25:16 PM

No resistance to date....

8/23/2010 12:12:12 AM

every other month rotation worming

8/21/2010 3:43:50 PM

My horses have not needed to be wormed in 8-9 years, so probably not.

8/21/2010 1:58:56 PM

ERP is 6-8 week in small strongyle but I do not have previous data about ERP,so can not say itshort

8/21/2010 10:35:27 AM

my horse do not show parasite in testing

8/20/2010 9:36:05 PM

I do rotational deworming, so far, so good.

8/20/2010 4:13:29 PM

very low key, Ivermectin is mostly still effective

8/19/2010 7:35:01 PM

But closed herd. No travel. No issues.

8/19/2010 7:26:11 PM

Negative fecal counts. Why worm when you don't have too. Only worm when needed.

Roundworm resistance to ivermectin products in foals

8/19/2010 12:10:41 AM

developed a resistance to ivermectin

8/18/2010 7:44:51 PM

I had a horse colic due to encysted strongyles, despite a typical rotation program

8/18/2010 3:03:15 PM

I now do rotational worming--hope it helps to prevent parasite resistance

8/18/2010 2:55:15 PM

I do not worm unless the egg count warrants it.

8/18/2010 2:32:39 PM

We worm daily with strongid C2X, and paste worm 2 times a year with great results.

8/18/2010 10:45:33 AM

I home test before using or not using anthelmintics

8/18/2010 8:26:04 AM

most especially ivermectin

8/18/2010 8:21:24 AM

FEC are essentially 0

8/18/2010 7:39:18 AM

Just did fecals and we're good.

8/18/2010 12:52:26 AM

now vet recommends fecal egg counts/my horses heavy egg shedders

8/17/2010 10:39:14 PM

Living in Houston,TX. we must rotationally worm monthly in the hot months.

8/17/2010 10:12:11 PM

how do you find out?

8/17/2010 10:04:10 PM

My fecal egg counts were negative on both my horses,.

8/17/2010 8:40:53 PM

low incidence of resistance to ivermectin

8/17/2010 6:23:28 PM

I use a fecal egg count program in order to avoid resistance to deworming products.

8/17/2010 4:48:06 PM

not yet, but I am concerned about it!

8/17/2010 4:36:47 PM

I am lucky to have a great veterinaian.

8/17/2010 4:28:52 PM

But I expect it to happen fairly soon now.

8/17/2010 4:23:09 PM

Thankfully, no

8/17/2010 4:07:48 PM

doing FECs to (hopefully) prevent resistance

8/17/2010 3:49:56 PM

We only worm if a stool sample comes back positive for worms. It's been 2 years now and no worms.

8/17/2010 3:33:21 PM

pinworms three years ago , had dewormed two yearlings every 8 weeks with ivermectrin and another

8/17/2010 2:09:34 PM

Exams by equine hospital show our deworming program (rotation) is effective.

8/17/2010 12:06:16 PM

I do rotational worming that is very effective.

8/17/2010 10:53:41 AM

I do rotational worming that is very effective.

8/17/2010 10:52:41 AM

bith roundworms and strongyles unaffected by ivermectin
