不同乐器演奏的音乐对奶牛内分泌及泌乳性能的影响

Effect of Music Played by Different Instruments on Endocrine and Milk Performance of Cows

2015年3月份至2015年8月份在新疆伊犁新生源公司巴彦岱牛场为研究大提琴、小提琴、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、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,实验组和对照组各18头。每期40d,试验当天起(0d),每20d采集血样并测定单产。结果表明,三种乐器演奏的音乐均能促进产奶量,其中小提琴演奏的音乐对产奶量的促进效果最佳,小提琴组整期产奶量较对照组高8%,差异显著(P<0.05)。大提琴组整期雌激素、生长激素水平分别较对照组低5.3pg/mL、0.58ng/mL,差异极显著(P<0.01);小提琴组整期促卵泡素水平分别较对照组低0.57mIU/mL,差异显著(P<0.05);低音提琴组整期催乳素水平较对照组低24.55uIU/mL,差异显著(P<0.05)。小提琴、大提琴和低音提琴均能通过调节内分泌激素来调控奶牛生产性能。

The experiment began in March 2015 and ended in August 2015 ,studied the influence of light music （cello music, violin music and bass music） on endocrine level and milk performance of dairy cows. 32 Holstein cows with similar age, weight, parity and milk yield were selected and randomly divided into two groups, namely, control group and test group, 18 for each. The test had three sections, each section 40 days. Each test started from 0 d. Every 20 days the daily yield, blood samples and milk samples were collected once. The results shows that,all these three types of music can promote milk yield and the violin music group shows the best result,the milk yield of violin group was 8 % significantly higher than control group through the entire period（P〈0. 05）. The estrogen and growth hormone level of cello group was 5. 3 pg/mL, 0. 58 ng/mL significantly lower than control group through the entire period（P〈0. 01）. The folli-cle stimulating hormone （FSH） level of violin test group was 0. 57 mlU/mL significantly lower than con-trol group through the entire period. The prolactin（PRL） level of bass music group was 24. 55 uIU/mL significantly lower than control group through the entire period（P〈0.05）. Violin, cello and double bass music can control the production performance of dairy cows by regulating endocrine hormone release.
