Abstract

Social isolation and exposure to a new environment induce hyperactivity, vocalizations and ACTH release in weaned Piglets acutely submitted to this stress. These reactions are increased by pretreatment with morphine (0.5 and 1 mg/kg) and decreased by naloxone (1 mg/kg), suggesting that endogenous opiates modulate emotional behaviour in Pigs.

摘要

社交隔离和接触新环境会在急性遭受这种应激的断奶仔猪中诱发多动、鸣叫和促肾上腺皮质激素释放。吗啡(0.5和1毫克/千克)预处理会增强这些反应,而纳洛酮(1毫克/千克)则会减弱这些反应,这表明内源性阿片类物质调节猪的情绪行为。
