Department of Clinical Veterinary Science, University of Bristol, Langford House, Langford, Bristol BS40 5DU, UK. Forty lame dairy cows were randomly assigned to receive a course of either the non-steroidal anti-inflammatory drug ketoprofen, or sterile saline, together with conventional treatment for lameness. The effect of the ketoprofen was measured by using locomotion scoring and by testing the cows' nociceptive threshold over a period of 28 days. The locomotion score of all the cows improved but ketoprofen had no significant effect on this change. However, in the cows that received ketoprofen the hyperalgesia associated with lameness, recorded using a nociceptive threshold test, was significantly modulated on days 3, 8 and 28 after their initial examination, drug administration and treatment of lesions.
