"Syringe too long for someone with small hands+"
My horses and I like the new gel. The syringe seems longer than the old one. I have small hands and it is difficult to use for 2 of my 9 horses who hate to be wormed.
"new gel formula is a step backwards"
The only complaint I have is new gel doesn't stick. I did two horses and both spit it out. It was a waste of time and money. I will not purchase this product, in the gel form again.
"WORKS FOR MY HORSES"
I have many horses, big, and the miniatures, plus have foals now and then, have used this wormer for years with good results. What I do is have the grain in the can add the wormer and mix it good-then pour into the feed bucket and they eat it all gone.As I had some horses that did not like it in the mouth,so I do it this way and no problem--had horses over 45 years. good luck
"Babies with worms. "
If anyone complained that it did not get worms in a baby, then you need to do your research. For babies, you do not depend on Ivermectin of ANY type, you need a Pyrantel Pamoate, or one of the other types to get roundworms. Roundworms after a horse turns a certain age do not live well in a horse (of course if they are encysted that is another story) but thrive in babies. Roundworms do not kill well with ANY ivermectin so I do my babies with Exodus, or a pyrantel pamoate product and do a full tube for a weanling and no problem. Then in the fall after the first killing frost I use Ivermectin. But a baby can die from roundworms if you depend on Ivermectin! Different wormers are better for different things. IE not all wormers get Tape worm.... treat with the correct wormer.
Always good! Saves us $$! Works great! And always the BEST service and SUPER fast shipping. We LOVE Jeffers!
I have used Jeffers brand Ivermectin for more than 20 years with NO complaint. The medication is the same - read the label or ask you Vet. I like the smaller tube, easier to carry in my pocket.
"Works just fine"
I asked my husband about the plunger, as he used 2 of these yesterday on our TWHs. He said they initially do work hard, but once you get them going they work just fine.
"horrible design "
I am not disputing the effectiveness of the medication but the design of the plunger itself is terrible. None of my horses like taking their wormer. It's an argument at best and a down right brawl at times. When I finally did get the tip in their mouths, it didn't want to squirt the wormer out quickly and it took me several times before they got the proper dose. I've used other brands with none of these issues. I'd rather pay more for a product that doesn't irritate me and my horses so much.
"I question those reviews that state this is a weak form of Ivermectin. It has the same amt of active ingredient as the ""big name"" compounds. Also the last time I checked with my Vet there is no resistance buildup to this product. Perhaps Jefferswould have something to say in this regard. A foal showing the high infestation as described by one user would scare me silly. Best check your husbandry."
Ivermectin is not a weak wormer for horses when using properly. All wormers kill the worm but not the eggs. If you would follow up with Exodus (same as Strongid, cheaper)on the 18th day after worming with ivermec you will see a hugh difference in your horse. Day 18, all eggs hatched, none in system. day 19 you again have eggs. I rescue horses and start with safeguard when I first get animal, as worms are always positive, but I fear for the amt of so this will keep them from colicing on the amount of kill. 1 week later I do the Ivomec, 18 days the Exodus. 30-days later i do a cheap wormer. i am then good til the weather changes and start all over again
"Good only in rotation"
I use this wormer alot because it's cheap and I don't have a huge worm problem with my horses. The brand is fine, but the active ingredient is very weak. In my experience it is only good for maintaining a horse with few/no worms. It is much less effective on horses with major worm infestations because ivermectin is so over used, that many worms develop immunity. Again though, it's great to use in rotation with more effective wormers just to keep a non-wormy horse healthy.
"Does a great job!"
I was concerned that this product was not as effective as the brand name wormers but I just wormed a 3 month old foal with this wormer a few days ago. I didn't think the foal would be that worming but OMG the amount of dead worms that came out were staggering!! Very effective product and I will be following up with another worming in 4 weeks to clean this foal out again! Great product at a great price!
"Not very effective"
I have bought this many times and thought it was working (along with rotating with other wormers). I was having trouble with a few of the younger ones and used this wormer, and looked for any worms to come out, and nothing. 10 days later had a fecal test done on a couple that were wormed with this and they had many worms. Rewormed with a different brand and got many worms removed and they are doing great now. I now avoid it and buy name brand and have not had any trouble since.
"Always Shop Jeffers!"
We always get this wormer through Jeffers ~ best price around for it and they often offer a deal on bulk orders! Plus the great service as always! Thanks, Jeffers!
"Works great on our goats!"
We use this on our four Angora goats, per instructions by our wonderful vet, and it has worked beautifully. The price is about right for my young co-goat-owners too. :)
