音乐在人类文化发展史上对人类的文明进化发挥了重要的作用。音乐能够影响人的情绪，音乐对人的作用不仅局限于日常生活的情绪调整，还应用到临床治疗之中，如减少疼痛感。同样，动物的研究也证实了音乐对绝大多数囚禁动物（动物园、实验室、救助站）产生积极作用，包括降低应激水平、缓解紧张情绪、增加愉悦情感等。尽管音乐实践在畜牧生产中的应用不乏范例，但这些应用缺乏理论基础，其实带有盲目性。而寥寥的研究结论不足以构成科学的理论体系，也就难以建立有效的实践运用方法。因此，本研究项目是基于音乐具有积极地影响畜禽的功效潜能，以断奶仔猪为试验研究对象，就音乐特征对仔猪产生的影响作用开展生物学反应机制的研究，旨在发现仔猪对哪些音乐特征产生认知，并观察仔猪从多个层面（分子通路检测、神经组织结构变化、生理反应机制及个体行为表达）上的反应特征，揭示仔猪对音乐特征的生物学反应机制，为科学建立音乐条件在实践中有效应用提供科学依据。

Music has played an important role in the evolution of human civilization in the history of human culture. Since music can affect people’s emotion, the role of music on people is not only limited to the emotion adjustment of daily life, but also applied to clinical treatment, such as reducing pain. Similarly, the results of studies on animals have confirmed that music has a positive effect on majority of imprisoned animals (zoos, laboratories, rescue stations), including reducing stress levels, environmental tensions, and increasing pleasure. Although there are many examples of the application of music practice in animal farming, these applications lack the theoretical basis, in fact, with Daze. And a few research conclusions are not enough to establish a scientific theoretical system, it is also difficult to find an effective method of practical application. Therefore, this research project is based on the potential of the function having positive impact on the efficacy of livestock and poultry and intends to investigate how do music characteristics affect piglets，in order to find the biological mechanism in their responses to music stimulation. Based on the impact of musical characteristics on the cognitive ability of piglets and combined with functional response of piglets from multiple organic levels. The results of this research will reveal the biological reaction mechanism of piglets to musical features and provide scientific basis for efficient application of music conditions in practice.
