Pour On Newbie

[Kell-inKY]

I usually feed my small herd the worming block, this year I saw a lot of ticks on them and decided I might try the Ivermectin generic pour on since it is supposed to work on all parasites? I didn't want to drag out my corral panels and portable squeeze chute in the pasture they are in right now so saw the opportunity to just pour it on them while they were in an old horse stable. They like to get in there mid day and stand around to keep flies off I guess. Anyway, it had a way for me to get above them and pour it on. Needless to say they were a little restless and I made a mess of getting it on as per directions. Some of them had half here and there, some were in one spot, they act like you are pouring acid on them or something. I think it was more the cane pole I had the cup taped to. :roll:

At any rate, this being my first time, I'm worried they got enough in the right spot. I could see some running down the side. Just wondering how in the world this stuff works by soaking in their tough hide? Next time I will inject them, but it is what it is this time. Should I be worried?

Get you a pump up sprayer and just soak them down with it.

kell,
Pour-ons have pretty poor efficacy. Studies done by Dr. Yazwinski in AR, as well as others elsewhere, indicate that in most cases, only about 30% of the applied dose actually gets to where it needs to be to kill worms. Absorption is pretty poor - and a lot of the activity experienced is due to the animals licking themselves/one another and ingesting it. Why not go ahead and inject or drench, and make sure the drug gets to where it needs to be to kill the worms?
On top of that, many of the generics, while they may fulfill chemical analysis as the stated percentage of active ingredient... appear not to be as effective as the 'name brand' stuff.

I will not use a pour on for internal parasite control, and don't bother with generics any longer...If I'm going to go to the trouble and expense of getting the cows in, running them through the chute, and treating them, I'd like to know that the anthelminthic I'm using will actually do the job. So what if I save $1 per cow...if it doesn't do what it's supposed to, I've wasted the time and $$ I invested. I'll go ahead and purchase the 'name brand' dewormer and inject or drench, depending on what drug I'm using.

Do what M5 says. A little pump sprayer and game on! It's just cows!

This is what I do. Just put out a bag or two of cubes . Walk down the line with the sprayer. I put the nozzle on stream so it will shoot about 10 ft. I kinda calibrated my sprayer by spraying the correct amount for 1000 lbs into a measuring cup and counted how long it took . Not perfect but you can get close .
