Research. Initially I wanted to test and then worm. What happened is that when the test came up ps

trying to transition to fecal exam results from strategic rotation of chemical classes with vete

Pick up all manure, rotate classes

I was told many years ago that rotating wormers was a bad idea by a vet working in R and D.

time of year, amount of horses in pasture togethor

Past effectiveness of the product with my horses

Ivermectin has always worked for my horses.

Prevention is far cheaper than the affects of diseases...

We worm entire barn including boarders on the same rotation, so far testing has proved it reliable.

Education as a vet tech.

what ive always used, then price

Ivermectin

Used to use ivermectin every 6 weeks, now rotating according to vet's suggestions

My vet couldn't provide a plan, just said to rotate them. I worked out a seasonal plan myself.

I use what I read about not aquiring a resistance to.

It depends on where horse is from, where he's been lving, when he was last wormed, and other factors

rotation is important and so is the price

Strategic rotation is best in my opinion

Apple Flavor!!

Equine supply store employee recommendation

Neg Fecals for 1 year . If I need to worm - Ivermectin after a frost. Safe, effective.

Statistics of efficiency, some chemical classes no longer work

currently using only diatomaceous earth as a supplement, with great results

What parasites are present at that time of year.

AND-what the vet says is the best to use--

My own research

also depends on lifecycle/time of year.

Fecals so you can know what's working and what isn't. How I found out PowerPac was useless in KY

Only Equimax, every 60 days

Don't feel confident of just fecals;also they don't detect tapeworms

my vet told me to repeat the last wormer that I had used, rather then alternating, which is wghat I

Vet & I work together based on Fecal samples for individual horses & general samples from the hear

Fecal exam isn't the only factor just one of several

apple flavoring

I don't deworm unless there is evidence of worms in my horses fecal exam, and then target the type

Research, research research

Plus I stay away from certain manufacturers.

Price and time of year

No rotation; defeats the purpose, ivermectin only, strongid 1x/yr; otherwise as necessary

cost

Price and rotating schedule recommended by vet

I purchase the year supply from catalog

Ivermectin all the way...

most cause my horse to colic but for some reason I-Gold doesnt

and my vets recommendation

Patent protection for current treatment formulas

What I know works.Plus many years of healthy equines to back it up.

PRICE - enough with the deworming polls.

research on internet leads me to my decision, which is to rotate, but not as often as some would

ivermectin, they haven't developed a resistance

rotation

Whats on sale

My stable manager's decision is based on fecal exams, strategic rotation and the vet's recommendation
