This article was #4 of the Top 25 most well-read articles on www.progressivedairy.com in 2012. Click here to jump to the video. It was published in the May 10, 2012 Extra. Click here for the full list of the Top 25.

In this video, Dr. Sheila McGuirk from the University of Wisconsin School of Veterinary Medicine demonstrates how to dehorn a young dairy calf. She includes the use of sedation, anesthesia and pain relief.

Q. How does the use of local anesthesia benefit the person performing dehorning?
With local anesthesia, the calf does not feel the heat applied so it keeps its head still.

When the head is still, the person doing the dehorning can place the dehorner in a correct position and keep it applied for the appropriate amount of time to have the best cosmetic appearance and little to no chance of horn regrowth.
—Dr. Sheila McGuirk, University of Wisconsin School of Veterinary Medicine

The NSAID used is banamine, which is approved for use in dairy cattle and is a prescription drug. Therefore, a veterinarian is required to be involved with writing and supervising your dehorning protocols, procedures and use of drug. You are correct in recognizing that the use of banamine in dehorning is extra-label, which is another reason for the important role of the veterinarian. The banamine label indicates use for fever associated with respiratory disease and inflammation associated with endotoxemia. My choice in using it for dehorning is based on the scientific evidence that pain and inflammation of dehorning is controlled better with use of a NSAID.

NSAID was used at the end. I thought those weren't allowed commercially for dehorning relief in the US?
