"Circle R Farms "
I have used this wormer for SHEEP & GOATS for several years, it is not labelled for either, i have never had a reaction, and it does a really good job, for a full grown animal i use the whole tube.
Your horse wormer is just the best. Every bit as good as the high priced stuff we get up here in Canada. Thanks for shipping 💓 💓
Just love Jeffers.! They are always thinking of a better way for their customers to be able to keep their horses in a low cost maintenance with great products. Thanks Jeffers.
Best price for regular ivermectin around
Great wormer and easy on the pocket
Great prices at Jeffers!
"Good proven wormer "
Have used these for years. Swap these out with other types of wormers. Can't bet the price. Horses stay healthy. From the minis to the horses.
We use this every year. It's affordable and my horses stay sleek and shiny. They don't even mind the taste.
Effective and with 25 plus shire horses its very affordable.
"Good product "
This dewormer is cheap, relatively safe and effective!
"Great product, great price"
Love the fact that I'm getting the same quality without paying the extra for a name brand.
"Jeffers Ivermec paste"
I have been using this as my main wormer for my cows, horses and dogs. Even a goat that would stop in now and again. Took some to a friend and wormed their sheep, goats, and chickens by squirting wormer on bread pieces. Use high fat horse feed when I worm the cows and horses with it. Squirt on my finger to worm the dog monthly, as it is the wormer and the heart worm medicine all in one. Nary have I had a dog with a cough and the die in their mid teens, so I must keep it here at all times. TYou
Great product! Works fabulously and you can't beat the price! Shipping is quick and ordering is easy! Highly recommended! We've been using this wormer for years and we run anywhere between 18-30 headed horses. Thanks Jeffers!
