With money being a little tight this year, I've decided to make the switch to a generic Ivermectin from Ivomec. I've had some tell me that the generic products aren't as good as Ivomec (or Dectomax, another brand name). However, when I made a comparison of active ingredients, the Durvet Ivermectin seems to have all the same ingredients, at the same levels, as Ivomec. Most importantly (I believe), Durvet has Ivermectin at the same strength (5mg/ml) as Ivomec. This tells me it should be every bit as effective.

My question is: has anyone use the Durvet product and done a direct comparison against Ivomec treated animals? The Durvet product is 1/5th the cost, making it especially attractive. Anyone use another generic, like Ivercide, and can compare it back to Ivomec?

We haye used the generic ivermectin for sevaral years.Have not done a scientific analysis-don't have a big worm problem-but we sure don't see any lice or grubs.
 
I've used the generic for the last couple of years- and don't see any difference...I was thinking of using Cydectin this year again- because some vets suggest you alternate or change after a few years, and its been about 4 years since I used Cydectin- since some parasites can build a resistance- but after looking at the price- I think I may just chance the generic a while longer...
 
I've used the generic stuff the last two years. $95 bucks for 5 liters in good old North Dakota. I would say it works just as good as the real thing.
 
The generics use the same drug as the namebrands, but they use a differint carrier that breaks down faster than the namebrands. So if the generic is fresh the chances of it working just as good as the namebrand is pretty good.
 
I'm sure everyone here knows my thoughts on this, so I won't go into detail again.

I do know that there was and is a huge kick-back to the seller for
promoting brand name avermectin products. That is one reason for
the difference in price.

I was present when a world renown parasiteologist told a room full of
veterinarians that the avermectin people owe the producer hundreds of
thousands of dollars because they ripped them off for so long.

Folks, if you really want to get worms, do it strategically. Watch your timing and the product you use. Safe-guard is the best dewormer out there. It is a drench or a feed-through product.
Use the avermectins for lice and grubs. The generic will do just as good as
any for that purpose.

De-worming in October isn't a good use of your dollar. Reinfestation is likely with any warm weather or moisture.

I'm not trying to make a dime here, I just hate to see your hard-earned
money wasted.

There is an article on parasites in the new BEEF magazine and I saved one from last year that has real good information about parasites.
If you want to PM me, I will help any way I can.
 
I've used the Durvet, as well as the Ivercide and the Agri-mectin. The only thing I haven't done is used them in a direct comparison with Ivomec. I can't tell any difference in any of them. I guess to have a fair and accurate test, it would require fecal counts, anyway.

In my area, I've found deworming all of the cows this time of year to be somewhat like Faster horses describes---a waste of money. But I always seem to have a few cull cows that need it after I wean calves, just to help them fleshen back up quick before they go to the sale. For that purpose, I really like the zero withdrawal on the Cydectin, so I try to keep some of it around. Seems like when I use the ivermectins on those culls, I end up being stuck with some of them longer than I wanted to keep them just because of the withdrawal period.
 
A little info I found to go along with some of the remarks here. Maybe worthless! :lol:

http://msucares.com/pubs/publications/p2023_72.htm

"Put aside a rumor. It has been said that animals become immune to deworming products. This is theoretically possible, but not probable because no study has documented this immunity. More damage is done to cattle from not deworming (or using a product at the wrong time) than is done by using the same product two or three times in a row"

From NC State University

Never apply famphur(Warbex) or fenthion
(Lysoff, Tiguvon) as pour ons during October,
November, or December, unless earlier
applications were made of these for grubs. Never
apply ivermectin, either as pour-on, or injectable,
during October, November, or December, as grub
related reactions can occur. Cattle treated with
ivermectin in August, and September, can be
retreated during winter for internal parasites,
mange mites, and lice, without danger of grub
related reactions.
 
That certainly is different info than what I have been taught.

How old is that information?

I've asked vets about when it is safe
to apply avermectin products and they say anytime.

I know with Warbex you need to be careful, but October? That
doesn't seem right. We've used Warbex mostly in October with
nothing bad happening. I do remember a rancher losing cattle using
Neguvon a long time ago.
 
I believe they were from 05. I did a search for 06 and this is all I've found.
January is good time to check for lice since their
populations increase with cold weather. If lice
populations warrant treatment, all animals must
be treated for effective control. If cattle had a
grubicide treatment like Warbex or a dewormer
that kills grubs like Ivomec, Dectomax, or
Cydectin last fall, they can be re-treated with any
of these products. If cattle were not treated for
grubs last fall, then they should be treated with
a product that kills only lice like Lysoff or lice
powder

The time key seems to be 're-treated'.
 
Faster, what Fedup wrote I've read before, and it confused me for a moment as well. Since its from NC, the months are just balled up for us Northern folks. If I waited until January to apply Ivermectin, the whole herd would be covered with lice. October seems to be about the ideal time up here. No grubs to worry about, and its late enough that there is lice protection right through until May or so.

I have had my vet tell me to hold off applying avermectin products in June/July, as thats when some parasite whose name escapes me right now are migrating up the legs. These parasites, if killed when in the leg muscles, can cause lameness.

I believe you are correct Rod. I thought about that last night. The other article was from Mississippi (University ext ser).
 
I think our one vet always told us to worm at 2 weeks after greenup... Of course he wante to worm at pregcheck and scour shot time too... He liked to sell the stuff a little bit too much..

Another vet just has you do worm load test a few times and worm when you need too... I like that method better ,lol.
 
IL rancher, the problem is that most vets have a machine that tests for dog worms. You need what I refer to as a "Wisconsin Spinner" to get a true analysis of cattle parasites. And you need to pick up the sample when it is warm.
(We have a name for the person who does that.) :wink:

If you have an Intervet rep in your area, call him. He'll take the sample and send it to an independent lab for you and probably won't charge you anything.

We have been fortunate to have parasiteolgists come here and set up their Wisconsin Spinner and run samples right on the ranch. It was so interesting. Those guys are so good, that they can tell you what you wormed with and when you dewormed. The man we worked with more than once was Dr. Flint Taylor from New Mexico. They were getting
data for worm species and wormloads in this area.

I learned a lot, now if I could just remember it all. :wink:

In this area, strategic de-worming is to be done 6 weeks after turnout.
 
We used Durvet last year ; I believe we paid $US 65.00 for it; exchange and GST brought it to around $C 90.00. Six of us rented a van and drove to Havre; figured we saved 10 grand on the load and had a good road trip out of the deal! I was satisfied with the results (primarily lice control) and would not hesitate to use it again. We planned to pour the cows in early spring to clean things up for the summer season as well but crappy weather cancelled that. As for resistance we had been using Dectomax for the past several years and it was time to switch to an ivermectin product anyways.
 
Thanks Cowsense and all. Gonna order some up tomorrow I guess.

On the Dectomax side, I never had much success with it. My local vet, who I have a great deal of respect for, suggested I try it, so I gave it a whirl. It may have been the type of year, but I had to re-treat about half the herd for lice come March, whereas I'd rarely re-treated with Ivomec. My neighbor tried it for a couple years as well, and he found the same thing.
