arnold, micatil is supposed to only be given subcutaneously and that is why you shoot the dart in the neck, where the skin is and use a 2/4 inch needle so it doesnt go into the meat. looks like whoever wrote that article has been reading our posts here on the boards. we had a good discussion just a few days ago about the time saving and animal saving usage of the dart gun. some people are set up to be able to get their cattle up to do these things, alot of us use the dart gun to keep the animal from getting excited and be able to doctor anywhere in the field, even if they are a mile from the nearest pen.
