Pekin ducks are motivated to access their nest site and exhibit a stress-induced hyperthermia when unable to do so.

The origins of floor-laying in ducks could be low motivation for a nest, or stress related to difficulties with accessing a nest (e.g. competition).

Pain-related behavior was not observed in dairy cattle in the days after liver biopsy, regardless of whether NSAIDs were administered.

For liver biopsy in cattle, it is routine practice to only provide local anesthesia (LA) to the skin and muscle layers, with visceral tissues remaining unanesthetized. Cattle being biopsied may therefore benefit from additional analgesia. This study aimed to determine if non-steroidal anti-inflammatory drugs would decrease post-biopsy pain in cattle.

Assessment of a carbon dioxide laser for the measurement of thermal nociceptive thresholds following intramuscular administration of analgesic drugs in pain-free female cats.

Objective: To assess the potential of a thermal carbon dioxide (CO2) laser to explore antinociception in pain-free cats.

Study Design: Experimental, prospective, blinded, randomized study.

Animals: Sixty healthy adult female cats with a (mean±standard deviation) weight of 3.
