What drug should be given to calves after dehorning?

• A. Ibuprofen
• B. Acetaminophen
• C. Meloxicam
• D. Aspirin

Answer: (C)

After dehorning, providing analgesia is essential to relieve pain and promote welfare during recovery. Meloxicam is the best choice because it is a long-acting NSAID approved for use in cattle to control pain and inflammation after procedures like dehorning. Its effect lasts longer, often allowing for convenient single-dose or once-daily dosing, which helps ensure the calf stays comfortable during the critical post-procedure period. It also tends to have a favorable safety profile among NSAIDs used in cattle compared with more non-specific agents.

Other options are less suitable for typical veterinary practice in cattle. Ibuprofen is not commonly labeled or approved for use in cattle, making dosing and safety guidance uncertain. Acetaminophen provides analgesia but has limited anti-inflammatory benefit in cattle and isn’t routinely used for post-surgical pain management. Aspirin can increase bleeding risk and cause gastrointestinal irritation in ruminants, making it a poor choice for a fresh surgical wound.

So, meloxicam best meets the need for effective, practical post-dehorning pain relief in calves.
