【摘要】：我国是一个猪肉消费大国,生猪饲养是我国畜牧业的支柱产业。玉山黑猪是特产于江西的优良品种,被列为国家级畜禽资源保护品种。生猪饲养环境福利严重影响猪只健康及生产性能,声音是饲养环境的重要方面。近年来,畜禽声环境福利的研究成为该领域国内外研究的热点之一,目前国内外关于声音对动物影响的研究,大都是从表面上或宏观方面研究音乐或噪声对动物行为和生长等的影响,对声音详细作用机制的研究报道却很少。本文以玉山黑猪35日龄断奶仔猪为研究对象,通过对照组和高、中、低频率音乐刺激断奶仔猪实验组的行为变化、饮水频率、采食量及饲料转化率、生长速度、胴体品质等性状的相关性分析,探讨有利于断奶仔猪适应断奶应激、提高成活率及生长速度等的声学环境。并通过对照组和实验组断奶仔猪血清生化指标、促生长相关激素的测定,剖析声学影响断奶仔猪生长性能的内分泌作用机理,为猪的声福利及其影响作用机制研究及健康养殖提供依据。本实验通过播放不同频率不同类型的音乐,最终证明,音乐对于仔猪的生长性能有一定的影响;在降低仔猪应激性,减少仔猪之间的咬斗方面有着较为显著的影响,可以提高仔猪的福利水平,但与音乐的类型有关;音乐对于仔猪血清指标与肉品质量上并无明显影响。
[Abstract]:Our country is a pork consumption big country, live pig raising is the pillar industry of our country animal husbandry. Yushan Black Pig is an excellent breed specially produced in Jiangxi Province, which is listed as a national livestock and poultry resource protection variety. The environmental welfare of live pigs seriously affects the health and production performance of pigs, and sound is an important aspect of feeding environment. In recent years, the research on the environmental welfare of livestock and poultry sound has become one of the hotspots in this field. At present, the research on the influence of sound on animals has been studied at home and abroad. The effects of music or noise on animal behavior and growth are mostly studied on the surface or macroscopically, but there are few reports on the detailed action mechanism of sound. In this paper, 35 day-old weaned piglets of Yushan Black Pig were studied. The behavioral changes, drinking water frequency, feed intake, feed conversion rate and growth rate of weaned piglets were stimulated by high, medium and low frequency music. The correlation analysis of carcass quality and other traits was carried out to explore the acoustical environment conducive to the adaptation of weaning piglets to weaning stress and the improvement of survival rate and growth rate. The endocrine mechanism of acoustics affecting the growth performance of weaned piglets was analyzed through the determination of serum biochemical indexes and growth-promoting hormones in the control group and experimental group. To provide the basis for the study of sound welfare and its influence mechanism and healthy breeding of pigs. By playing different kinds of music at different frequencies, it was proved that music had a certain effect on the growth performance of piglets. It can improve the welfare level of piglets, but it is related to the type of music, but music has no significant effect on serum index and meat quality of piglets.
