I have a pregnant cow due 1-3-13 that has a horn growing into her temple I have tried to ignore it but it has broken through the skin. I have bought an electric dehorner with the thought of burning the horn then using a saw blade in the burned region to minimize bleeding. I have also bought a temporary nose ring to control the head. I have a head gate in a calving barn to control her. I also bought some aluminum metal that I will shape with tin snips to put under the horn so I dont cut the skin. Any other thoughts I have a powder to minimize bleeding. Should I also vaccinate her at the same time?
