We start our conversation by discussing a typical dehorning protocol on beef and dairy farms as well as methods for providing local anesthesia to the horn bud. The objective of this study was to determine if the duration of analgesia could be extended using additional anesthesia and analgesia protocols in calves that were scoop dehorned. All treatment groups received a cornual nerve block with lidocaine and the four treatment groups included an additional infiltration around the horn bud with ethanol, lidocaine alone, lidocaine with meloxicam, and a bupivacaine liposome suspension. Martin discusses the outcome variables they tested and walks us through how these measurements were performed by the investigators.
The results indicated that none of the treatments extended the duration of analgesia based on the outcomes measured, however it did emphasize that multimodal analgesic therapy with a local anesthetic and oral meloxicam is the gold standard by working synergistically and providing a longer duration of analgesia. Martin also discusses the opportunities for future research in pain management in cattle, including investigating products and procedures that are practical regimens to extend the duration of analgesia for a variety of painful procedures and conditions.
