不同类型音乐对奶牛泌乳性能及蛋白质代谢的影响

摘要

2016年在新疆开展了不同类型音乐对奶牛产奶性能和蛋白质代谢影响的研究.试验选取年龄、胎次、产奶量接近,饲养管理水平完全相同的荷斯坦泌乳牛80头,随机分成4组,每组20头.试验组每日分别播放哈萨克族音乐、贝多芬《田园交响曲》、维吾尔族音乐,对照组常规饲喂,不播放音乐.结果表明:哈萨克族音乐可提高BUN(尿素氮)含量,降低CREA(肌酐)含量;贝多芬《田园交响曲》可提高AST(谷草转氨酶)含量;维吾尔族音乐可提高TP(总蛋白)、GLB(球蛋白)含量.贝多芬《田园交响曲》较哈萨克族音乐而言,可提高CREA、AST含量.维吾尔族音乐较贝多芬《田园交响曲》而言,AST、CREA含量显著下降.%The effects of different types of music on the lactation performance and protein metabolism of dairy cows were studied in 2016 in Xinjiang.Eighty heads of Holstein dairy cows with the similar age, parity and milk yield under the same level of feeding management were selected, and they were randomly divided into 4 groups (20 heads in each group).The dairy cows in various groups were treated by playing Kazak music, Beethoven's "Pastoral Symphony" or Uygur music everyday, and not playing music was taken as the control.The results showed that: playing Kazak music could increase the content of BUN, and reduce the content of CREA;playing Beethoven's "Pastoral Symphony" could increase the content of AST;playing Uygur music could improve the contents of TP and GLB.Playing Beethoven's "Pastoral Symphony" could obtain higher contents of CREA and AST than playing Kazak music, while playing Uygur music could significantly reduce the contents of CREA and AST as compared with playing Beethoven's "Pastoral Symphony".
