Double dosing wormers

Posted by Juliana Goodwin on July 27, 2014 at 12:57pm in Health

I'm wondering if anyone can tell me their experience of double/triple dosing dewormers?  I know levasole isn't one you want to mess with but what about regular Ivermectin, Ivo+, Doramectin, Cydectin, Valbazen....?

I think I am going to have to do some nasty cocktails to knock some of these worms down (I am also aggressively changing herd size, feeding practices ect to try and help with the problem too).  I'd like to hear that another goat survived the cocktail before I give start doing it!

    Okay...I will try all 3 at once.  I am doing everything else I can think of too, I have halved the herd size to reduce stocking rate on pasture and also to allow for more pasture resting, my baby bucks & weanling does are on dry lot for the time being because I can't rest any pastures if they stay out.  I just bought all new buckets so I can start a new system of feeding that will hopefully keep feet out of the food better...

    I thought I covered my bases in preventing this but obviously I bought these worms and brought them in without realizing it at some point...but no one has died, thank goodness I started the fecals though or I definitely would have lost Halley.

    This is also on the list of why I would like to get the heck out of Florida...

    I know they double the dose of Safeguard when treating meningeal worm, and that does not hurt the goat, but I do not know about other dewormers. If a regular dose is not killing the worms, it is unlikely that a higher dose would do it once you have a resistance problem. Using different classes of dewormers at the same time is your best bet. If a combo of cydectin and levasole did not kill the parasites, they are really tough. You would just add Safeguard or Valbazen to that combo.

    Yes I am clear on what is in what class & the combos I have done so far were like cydectin & levasole together, or ivermectin and morantel.  

    Have you ever doubled the "goat" dose?  So, say cattle dose is 1 ml per 100lb, goat dose would then be 2 ml per 100bl, what about giving 4ml per 100lb?  Reason I ask is due to resistance problems and worms I can't seem to kill.

    Cattle dosage is doubled for goats on everything except levasol (levamisole), which is only increased by 1.5 times. Yes, it is scary the first time you do it, but so far I have not heard of anyone having a problem with using 2-3 dewormers at one time. The thing you MUST get correct, however, is to make sure you are using drugs from different classes. For example, ivomec, ivermectin, doramectin, cydectin, moxidectin, are all in the same class (some are even the same drug with different names), so you would NOT give two of them at the same time.

    Luckily it is pretty easy to figure out what is in each class. All of the ones I listed are clear liquids. Valbazen and Safeguard (fenbendazole) are both white liquids. Yeah, they do have a Safeguard feed additive now, but the original was/is a white liquid. Morantel tartrate annd levasole are normally solids, so morantel tartrate is commonly sold as a feed additive. Levasole is a capsule (which is huge and impossible to get down a ND) or a powder that is reconstituted with water. Once reconstituted, it is only good for about 3 months.
