不同乐器演奏的轻音乐对泌乳奶牛神经递质水平和泌乳性能的影响

2015年3月至2015年8月在新疆伊犁新生源公司巴彦岱牛场为研究大提琴、小提琴及低音提琴演奏的轻音乐对泌乳牛神经递质和泌乳性能的影响。选取体重、年龄、胎次及泌乳量接近,健康状况良好,饲养管理水平完全一致的荷斯坦泌乳牛36头,随机分成2组,试验组和对照组各18头。试验分3期,每期40 d,每隔20 d采集一次血样和乳样并测定单头产奶量。结果显示,与对照组相比,3种乐器演奏的音乐均能促进产奶量,其中小提琴音乐组的产奶量显著高于对照组(P < 0.05);小提琴演奏的音乐能显著增加血清中甘氨酸(Gly)含量,显著降低神经肽Y (NPY)含量(P < 0.05);低音提琴演奏的音乐能显著降低NPY含量(P < 0.05)。结果提示,可选用小提琴演奏的音乐作为奶牛生产生活的环境音乐。

Effect of Different Instruments Playing Light Music on Neurotransmitters Level and Milk Performance of Dairy Cows

The experiment was conducted from March 2015 until August 2015 at Bayan Dai cattle farm,Xinjiang Xin Sheng Yuan company in Yili.To study the influence of light music (cello music,violin music and bass music) on neurotransmitters levels and milk performance of dairy cows,36 health Holstein cows with similar body weight,age,parity and milk yield were randomly divided into two groups,control group and test group,each group with 18 heads.All these cows were managed at the same conditions.The test had three sections,each section lasted for 40 days.Every 20 days the daily yield was determined,and the blood and milk samples were collected.The results showed that all these three instrumental music could promote milk yield and the milk yield of violin music group were significantly higher than that of the control group (P < 0.05).Violin music significantly increased Gly level and reduced NPY level (P < 0.05).Bass music could significantly reduce NPY level (P < 0.05).The results suggested that violin music could be used as the environment music in dairy cows production.
