Context Music induces physiological responses in animals, and as an enriched environment, it may have a positive effect on behaviour and productivity. Aims This study aimed to determine the effects of different kinds of music on immunity, stress response and performance of piglets. Methods In total, 144 hybrid piglets (Yorkshire × Durac × Minpig) at the age of 7 weeks were divided into three treatment groups: slow-tempo string music (65 beats per min), fast-tempo wind music (200 beats per min), and control (i.e. no music). Exposure to music lasted for 42 days, from 8 to 14 weeks of age. During the experimental period, behavioural activities were observed, and physiological parameters, immune responses and growth performance were measured. Key results Results showed that long-term music exposure increased (P 0.05) on walking, lying, exploring, fighting or feeding behaviours. No effect (P > 0.05) was found on the levels of growth hormone, salivary cortisol, serum cortisol, adrenocorticotrophic hormone, β-endorphin or dopamine, or on the performance of growing pigs. However, the specific music type slow-tempo string significantly (P < 0.05) increased interleukin-4. Conclusions Long-term exposure to music does not affect stress response or growth performance in piglets. However, it promotes positive mood as indicated by increased playing and tail-wagging activities, and induces positive immunomodulation through increased interleukin-4 levels in piglets. Implications Exposure to music may be used to promote positive mood, and hence enhance welfare, in piglets.

长期接触音乐对仔猪行为、免疫力和生产性能的影响

背景音乐会诱发动物的生理反应,作为一个丰富的环境,它可能对行为和生产力产生积极影响。目的 本研究旨在确定不同类型的音乐对仔猪免疫、应激反应和生产性能的影响。方法 将144头7周龄杂交仔猪(约克夏×杜拉克×明猪)分为慢节奏弦乐(65次/分钟)、快节奏风乐(200次/分钟)3个治疗组。 ,和控制(即没有音乐)。接触音乐持续了 42 天,从 8 到 14 周大。在实验期间,观察行为活动,并测量生理参数、免疫反应和生长性能。主要结果 结果表明,在步行、躺下、探索、打架或进食行为。对生长激素、唾液皮质醇、血清皮质醇、促肾上腺皮质激素、β-内啡肽或多巴胺水平及生长猪的生产性能均无影响(P > 0.05)。然而,特定音乐类型的慢节奏弦显着(P < 0.05)增加了白细胞介素4。结论 长期接触音乐不会影响仔猪的应激反应或生长性能。然而,它通过增加玩耍和摇尾活动来促进积极情绪,并通过增加仔猪的白细胞介素 4 水平诱导积极的免疫调节。影响 接触音乐可以促进仔猪的积极情绪,从而提高福利。血清皮质醇、促肾上腺皮质激素、β-内啡肽或多巴胺,或对生长猪的性能。然而,特定音乐类型的慢节奏弦显着(P < 0.05)增加了白细胞介素4。结论 长期接触音乐不会影响仔猪的应激反应或生长性能。然而,它通过增加玩耍和摇尾活动来促进积极情绪,并通过增加仔猪的白细胞介素 4 水平诱导积极的免疫调节。影响 接触音乐可以促进仔猪的积极情绪,从而提高福利。血清皮质醇、促肾上腺皮质激素、β-内啡肽或多巴胺,或对生长猪的性能。然而,特定音乐类型的慢节奏弦显着(P < 0.05)增加了白细胞介素4。结论 长期接触音乐不会影响仔猪的应激反应或生长性能。然而,它通过增加玩耍和摇尾活动来促进积极情绪,并通过增加仔猪的白细胞介素 4 水平诱导积极的免疫调节。影响 接触音乐可以促进仔猪的积极情绪,从而提高福利。结论 长期接触音乐不会影响仔猪的应激反应或生长性能。然而,它通过增加玩耍和摇尾活动来促进积极情绪,并通过增加仔猪的白细胞介素 4 水平诱导积极的免疫调节。影响 接触音乐可以促进仔猪的积极情绪,从而提高福利。结论 长期接触音乐不会影响仔猪的应激反应或生长性能。然而,它通过增加玩耍和摇尾活动来促进积极情绪,并通过增加仔猪的白细胞介素 4 水平诱导积极的免疫调节。影响 接触音乐可以促进仔猪的积极情绪,从而提高福利。
