Dewormers: Pour-On v. Injectible

by **BoJack Cattle** » Thu Apr 02, 2009 12:13 pm

Does anyone know of any studies that prove injectible de-wormers perform better than pour-on's or vice versa?

The only differance that I know of is, there is no hold time on butchering with pour on.

Which dewormer would this be?? Last I checked Ivomec pour-on had a 45 day withdrawl. Cydectin and the others are similar I think.....

Cydectin has no slaughter or milk withdrawal according to label.

Eprinex has no slaughter withdrawal time either. Not trying to hijack but wasn't there a lawsuit a while back with some pour on dewormer causing birth defects or dead newborns, anybody know about it.

Ask your vet, see what he says. My vet likes the injectible, but I think thats because its easier for him to do. :nod:

in most istance the injectable is cheaper to use and you don't have to worry about the weather with it like you do a pour on
as far as which one is more effective I don't know of any significant difference in them

We go back and forth between the two. Ivomec pour on has a 45 day also.

We pour on in the early summer and inject in the fall. Has worked well so far.

I do the same...but I do use Cydectin Pour-On rather than Ivomec products.

WE USE IVOMEC POUR ON. HAS 45 DAY W/DRAWAL.

I don't think there are any pour-on's that take care of liver flukes if that is a problem in your area. Probably other things too that one will take care of but not the other.

We use a drench in the spring and injectable in the fall

I heard a Dr. Thomas Yazwinski from the University of Arkansas at a cow calf clinic here in east Texas last week talk on this subject. He liked injectables over pour-ons for better control and less chance of developing resistance by having a sub lethal dose stretched out ass the product leaves the animal's system.

I just finished reading an article on this today. It stated a 45 day wait before slaughter with pour on. It was also suggested that for here in Ky that deworming be done in late June or early July no matter whether you injected or used pour on. The lady that wrote the article actually preferred pour on as she felt there were other advantages such as possibly keeping down lice and flies and no needle marks on the carcass.
