Saline-induced birds had a significantly higher skin temperature (± SD) than saline-sham birds (37.6 ± 0.8 °C vs. 36.5 ± 0.5 °C; Z = −3.47, P < 0.001), consistent with an inflammatory response. Saline was associated with significantly lower thermal thresholds (TT) than analgesic treatment (meloxicam: Z = 2.72, P = 0.007; carprofen: Z = 2.58, P = 0.010) in induced birds. Saline-induced birds also had significantly lower TT than saline-sham birds (Z = −2.17, P = 0.030). This study found direct evidence of an association between inflammatory arthropathies and thermal hyperalgesia, and showed that NSAID treatment maintained baseline thermal sensitivity (via anti-nociception). Quantification of nociceptive responsiveness in a predictable broiler pain model identified thermal anti-hyperalgesic properties of two NSAIDs, which suggested that therapeutically effective treatment was provided at the doses administered. Such validation of analgesic strategies will increase the understanding of pain associated with specific natural broiler lameness types.
