RESUMO

To determine if ketoprofen, in addition to local anaesthesia, reduces pain following dehorning, we experimentally dehorned dairy calves, less than 2 weeks of age, with (20 calves) or without (20 calves) intramuscular injections of ketoprofen. All calves received a local anesthetic (lidocaine) prior to dehorning and were dehorned with heat cauterization. Cortisol concentration was measured via jugular blood samples taken immediately before dehorning and at 3 and 6 hours following dehorning. Calf behavior was recorded between 0 and 2, 3 and 5, and 6 and 8 hours following dehorning. There was no significant (P > 0.10) effect on creep feed consumption, cortisol concentration, or any of the behavioral measures during the time periods studied. However, the difference in cortisol concentrations from the time of dehorning until 3 hours later was significantly lower (P < 0.05) in the ketoprofen-treated group. These results suggest that ketoprofen, in addition to local anesthesia, may alleviate short-term pain following dehorning with a butane dehorning device in dairy calves less than 2 weeks of age.
