- Proof would have to stand up to repeated testing.
- I use diatomaceous earth, haven't used a commercial wormer in 16 years.
- I use a daily wormer plus spring and fall treatments with Ivemectin or Quest have never had a colic
- we deworm 2 times a year
- I agree we have to change our ways and catch up to the 21st century for the good of our horses.
- do fecal test
- No such thing as 'proof' but good evidence to do something alternative would be needed before change
- I will continue my horse's rotation program, as I feel it does help him.
- Proof that it's not necessary via fecal count every so often, which would determine....worm or not.
- only worm when fecal shows high egg count
- My horses' fecal tests are normal. Equimax give in Dec. for tapes.
- Vet has just changed us to "test" and worm if needed based on results.
- accurate fec from my vet every 3 months
- I have changed to using fecal samples to determine deworming
- A fecal egg count shows what's really there, as opposed to what we worms think are there.
- reasonable cost and easy way to do test
- Itave already stopped and am doing fecal counts
- i get fecal worm egg counts done twice yearly
- I use the vet-recommended dewormer as needed based on FEC tests
- I do worm egg counts, which show normally 0, and give Equimax in November for tape worm.
- Our barn owner dictates who gets what, and when. She's the only barn, in our area, with NO parasites!
- Availability of easy tests would help
- I try to keep up with new info and have routine discussions with my vet about best/latest ideas.
- Using fecal egg counts to determine schedule.
- i have been doing FEC for a year & LOVE the fact my horse does not get chemicals she doesn't need
- we only worm if fecal tests shows it's necessary
- I actually stopped this year/ Had a fecal done and my horse had no eggs.
- Only deworm 2-3 times a year anyway
- it's already been proven that rotational deworming is out of date!
- i use a daily wormer.
- I do fecals on my own horses and worm them as needed
- I do a fecal count twice a year and then use whatever the vet recommends.
- If fecals were not so expensive for several horses
- its worked for over 30 years for me "why change"
- I use targeted de-worming with egg counts
- I do a fecal egg count, then rely on vet's recommendation.
- I do fecal worm testing before deworming and then determine from the results which dewormer to use.
- Fecal testing then use the right product.
- I worm in the spring and then do stool collections to take to the vet for egg counts.
- Have not rotated for many years--resistance in SE makes it useless
- N.O.M.S. powder works GREAT!
- most do not work anymore
- Sheep industry learned what happens w/routine deworming-resistance to all products.
- Stopped for a year. Used only Quest Plus. Fecal exam after 1 yr on 7 horses, 0 parasites.
- "closed" herd, fecal exams show minimal infestation, deworm only as necessary
- Without the OK from my vet, i would not stop my current worming program.
- I use feed-thru wormer and have never had a problem in 10+ yrs
- I have stool samples checked and then worm accordingly. There is really no fool proof method
- Some I rotate and some I don't. Depends on the horse.
- have tried rotations and when not using zimectrin gold my horses got pin worms
- if the vet says switch, I will
- I do an annual fecal exam with my vet to determine what deworming is required.
- Too much info showing rotational deworming is no longer valid. We use Pfizer's Horse ID program
- I only worm when the fecal exams indicate it's necessary; then I know what type of worm to eradicate
- Cheap do it yourself fecal tests
- I rotate thinking i should. but what about daily deworming products? Is this system better?
- Due to the resistance issues I now have a fecal run every 8 weeks and deworm based on that.
- Two times per year deworming not necesery to rotate
- Something that works one time a year on all worms
- I do fecal exams every three months and worm for the specific worms present.
- Scientifically proof that rotational worming is a waste of money...
- The price of taking a fecal sample analyized will stop most people from checking it.
- Not every parasite dies with iver, and even with it resistance cd someday develop. Rotation is safer
- ROTATION IS RECOMMENDED BY VETS IN THE SW.
- Testing fecal count just gives vets another way to makemore $ with the number of times it needs to b
- Will rotate unless vet says not to. Dang those nasty things.

- I have my horses on a daily wormer and treat them with Equimax twice a year.
- my vet having equipment to test feces
- Fecal exams that are cheaper than dewormers
- I use fecals and have been told by my vet NOT to rotate.
- Seems to me this is such old news. I'm amazed that anyone continues to rotate wormers.
- problem is, fecals do not tell the whole story so it's impossible to know the actual count
- I weighed advice from vet to limit worming and not work regular every 3-4 months & no need to rotate
- using FEC and per vet recommendation have tailored a dewoming program for our farm
- I do fecal egg counts twice a year, 3 equines, zero eggs,treat for tapeworms spring & fall.

- Based on an educational seminar I attended, I now only work according to fecal count requirements
- I still rotate, but according to season and the priminant concern of that season.
- I deworm based off of FEC results.
- If "natural" product could be offered, I would jump on it. Parasites have evolved w/horses
- I currently use fecal test results to determine my worming needs.
- I would need to have proof.
- I check fecals
- I rotated at one time, but when my horses still showed signs of worms I switched to a daily dewormer
- The farm I board at does Ivermectin every 2 mo. except in Jan when we use Zimectrin Gold
- I want to stop but can't convince the barn owner who firmly believes in it!!
- however - I only deworm 3x per year
- I understand science is advancing, but my horse is healthy on a rotation.
