- Daily wormer and biannual ivermectin
- fecal counts that don't indicate the need for rotation or worming.
- I use Strongid C2X with twice a year Equimax.
- I usually target a specific parasite and choose the de-wormer which I think works best for that para
- I rotate pastures, so I worm when moving them as not to carry along new pests to the new area.
- I use a daily wormer plus spring and fall using Quest or IV Gold
- use the daily wormer and 2x a year ivermectrin per vet
- My understanding is that ivermectin is all that is needed for worming my horse.
- I use Quest/Quest Plus
- Our horses are on daily wormer per our vets suggestions, and paste every 6 months - great results!
- being able to afford/having access to regular fecal exams

- I had fecal egg counts done
- A recommendation from my vet, and proof it isn't working. my
- use peer-reviewed articles to make decisions.
- Don't rotate, never have. It's not necessary and is more likely to lead to resistance.
- I have always used rotational dewormers and have never had a problem.
- Per my vet, every year I alternate daily & rotational program
- No worms detected after doing fecal samples
- My horses have a lot of acreage to roam on, so I worm infrequently 1 or 2 x per year
- scientific evidence that offered something better
- used to be on daily strongid and it is not recommended because of resistance
- My vet would have to prove to me that rotating dewormers wasn't working before I would stop.
- I rarely rotated when I wormed. I used Ivermectin. It's been over 1 year of NEG fecal counts.
- I use quest & quest plus all year

- Free fecal checks by a vet to indicate presence/type of parasite and recommend appropriate wormer.
- through fecals that the count was low
- ivermectin year round does the trick
- If they came up with a dewormer that kills everything, every time.
- we have just started doing fecals and treating as needed.

- After 2 out of 3 horses showed low/no egg count, I stopped rotational deworming.
- In FL I give mostly ivermec based wormers, but will do PowerPak w/ Safeguard 1x/yr.
- being on a farm that does a better job of manure disposal.

- I do rotation and it has worked for me several years

- Any developed treatment that is 100% foolproof!!!
- could find a natural product, not harsh chemicals
- I only change wormers when egg counts go up or to target one kind of worm
- Fecal egg counts! Have already stopped worming unless necessary!
