音乐对缓解肉鸡热应激损伤的作用研究

Effect of Music on Relieving Heat Stress Injury in Broilers

为研究音乐对缓解肉鸡热应激损伤的作用,将400只21日龄罗斯308肉鸡随机分为4个处理(室温组、音乐组、热应激组、热应激+音乐组),每个处理5个重复,每个重复20只,试验期为21 d。试验结束,随机选择20只(每个重复1只)进行内脏器官指数、抗氧化酶活性和热休克蛋白表达分析。结果显示:音乐能帮助热应激肉鸡肝脏中谷胱甘肽过氧化物酶(GSH-Px)活性、过氧化氢酶活性、总抗氧化能力(T-AOC)维持正常,并能在一定程度上缓解热应激对肉鸡血液丙二醛含量、T-AOC活性、超氧化物歧化酶活性的影响,且能改善热休克蛋白表达水平。结果表明,音乐可以在一定程度上改善环境高温对肉鸡生产的影响。

To investigate the effect of music on relieving heat stress injury of broilers, 400 21-day-age Ross 308 broilers were selected randomly and divided into four groups(Room temperature group, Music group, Heat stress group,Heat stress+music group), each group had 5 replicates with 20 broilers per replicate. The experiment lasted for 21 days.By the end of the experiment, 20 broilers were selected randomly(one for each replicate), the immune organ index,the activity of antioxidant enzymes and the expression of heat shock protein were analyzed. The results showed that music could help maintain normal levels of glutathione peroxidase(GSH-Px), catalase and total antioxidant capatity(T-AOC) in liver of heat-stressed chickens, and alleviate the effect of heat stress on malondialdehyde content, T-AOC and superoxide dismutase level in serum to some degree, and also improve the gene expression levels of heat shock proteins.The results suggested that music could improve the effect of environmental high temperature on broiler production to a certain extent.
