摘要
2016年10—12月在新疆伊犁中洲公司巴彦岱牛场研究藏族音乐、塔吉克族音乐、彝族音乐对奶牛泌乳性能的影响。试验选取产奶量、年龄、胎次相近的荷斯坦泌乳牛64头,随机分成4组,即藏族音乐组、塔吉克族音乐组、彝族音乐组及对照组,每组16头。试验组早、中、晚3次给料时间各播放音乐2 h,试验3组音乐分别选用藏族音乐、塔吉克族音乐、彝族音乐中各自最典型的音乐15首,对照组常规饲喂。正试期当天起(0 d),每隔20 d采集奶样、血液各1次。预试期7 d,正试期60 d。结果显示,塔吉克族音乐组、彝族音乐组产奶量分别较对照组低,且差异极显著(P<0.01);藏族音乐组产奶量较对照组低,且差异显著(P<0.05);藏族音乐组、彝族音乐组产奶量较塔吉克音乐组高,且差异显著(P<0.05)。说明频率最接近常速音乐的藏族音乐对维持奶牛产奶量效果最佳,塔吉克族和彝族音乐的作用有限。藏族音乐、塔吉克族音乐、彝族音乐对对奶牛乳成分含量均无显著影响。
The experiment was conducted from October 2016 until December 2016 at Bayandai cattle farm, Xinjiang Xinshengyuan company in Yili. To study the influence of Tibetan music, Tajik music, Yi folk music on milk performance of dairy cows, 64 health Holstein cows with similar milk yield, age and parity were randomly divided into four groups, named as Tibetan music group, Tajik music group, Yi folk music group and control group, each group with 16 cows. Each experimental group selected and used 15 typical music of each nationality, played at feeding time, third times a day, each time 2 h, and not playing music was taken as the control. Every 20 days the daily yield was determined, and the blood and milk samples were collected. Preliminary trial period were 7 days, trial period were 60 days.The results showed that Tajik music and Yi flok music group＇s milk yield were significiantly lower than control group（P〈0.01）;Tibetan music group＇s milk yield was lower than control group（P〈0.05）. Tibetan music and Yi folk music group＇s milk yield were higer than Tajik music group（P〈0.05）. We learned that Tibetan music had the best effect of milk performance maintenance, Tajik music and Yi flok music had limited effects. Tibetan music, Tajik music and Yi flok music had no significant effect on milk ingredients.
