"Horse didn't try to spit it out"
It's Ivermectin. No reason to buy a name brand if it has the same main ingredient. I just bought it because it was cheap but to my surprise my horses took it no problem. They always try to spit out Equimax and Zimectrin. It doesn't smell as "mediciny" as the otherse either. My goal is not to "torture" them with dewormer so if it's cheap and palatable, I'll be buying this for the annual deworming.
Great price for great quality stuff. Will buy again
"Best price ever!!"
We have a number of horses and this is the best price on a quality product.
"Very good product and price!"
Happy with purchase
Ivermectin works great on pastures horses. Price is do reasonable
"Jeffers Ivermectin - Great product"
I have used many different brands of ivermectin over the years and this is by far my favourite. The horses don't mind the taste and the consistency is great - thin enough to dispense easily but thick enough that it stays put.
the price is great. my husband is a veterinarian and he said it had everything that the horse needed as part of a rotational program
"Jeffers horse wormer"
Excellent product for the price!!! just read the label, same ingredients, at a fraction of the price of the others !!!!
I use this every 4 months and rotate with Strongid so I worm every 2 months. The product seems to work well as long as you use it when you are supposed to.
Great price and have been buying it for about 8 years. Jeffers has been wonderful to deal with. Very fast shipping.
"Great product for price"
Great price on this product. I use it on all of my livestock. sheep, goats, donkeys, horses, camel... Why pay 3-4 times more for this product just to have another name on the label...
Great product at great price
"Jeffers I vermectin "
Keep up these great products that work 👍
"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 💓 💓
