The ear thing works good once you have done a few , and get the technique down. I spent all day at one of those seminars to learn it, but I can lay it on ya in two minutes.LOL!!
The needles you get with the Exceed are bevelled differently than a regular needle. Really blunt. It punches a hole in the hide pretty much. The main thing I learned at the seminar was that if you inject into a vein it will kill them instantly! On the back of the ear are a couple of big arteries, they were shaving the ears and showing us how to put the meds between the viens! Or you could put it on the top, front of the ear (nice flat part),
where there are no viens to hit. I can't imagine shaving all those ears or risking hitting a vein, so I place all mine right on top, and have never had any sort of problem this way.
Technique is important or every bit will run back out the same hole it went in. Insert the needle under the hide as if you were placing an implant. Put your thumb over the needle at the entry point and apply pressure as you inject. Keep your thumb over the hole as you pull the needle back out. You have a bubble of Exceed on top of his ear. The most important thing is to keep your thumb over the hole. Take your other hand and "milk" that bubble towards the calfs head away from the hole. Strip it a few times and you feel the bubble go away.
Sometimes you see a drop ooze back out, but they assured me this was O.K. and was figured in the dosage. I hope this doesn't sound too complicated because it's not. It is just like implanting really, you just rub it afterwards.
I see the same thing you do with some of the other antibiotics that have been around awhile. Many just don't seem to respond like they once did. I have only used the Draxxin for a month or so, but have been REAL PLEASED. The price tag scared me at first ($280) for a little 100cc. bottle. But it is a one time treatment and only uses 1cc. per hundred wt. So that makes it pretty comparible in price to the others if I'm figuring right. The part I love is treating them early and putting them back out on something green vs. standing in a sick pen.
I think grass is good medicine in itself. The Draxxin is used in the neck sub-Q, and they reccomend changing meds if there is no response within a couple of days. Luckily, I haven't had much problem with this as long as I catch them early. Sorry about the wordy post, I hope it was beneficial.
