| 摘 要： | 本试验旨在探讨轻音乐对奶牛产奶量及血液激素水平的影响。选取产奶量、年龄、胎次、泌乳期相近的荷斯坦泌乳牛32头,随机分成2组,每组16头。试验组于早、中、晚3次给料时间各播放轻音乐2 h,轻音乐选用理查德·克莱德曼的经典钢琴曲20首,对照组常规饲喂。预试期7 d,正试期60 d。正试期当天起(0 d),每隔10 d测定单产1次并采集血样1次。结果表明,试验组产奶量在第10、40天时显著高于对照组(P<0.05);试验组产奶量在第20、30、50、60天时高于对照组,差异均不显著(P>0.05);整个试验期,试验组平均产奶量较对照组高1.72 kg,差异极显著(P<0.01)。整个试验期,轻音乐能提高奶牛血液中γ-氨基丁酸(GABA)、生长激素(GH)含量,降低血液中皮质醇(COR)、五羟色胺(5-HT)含量,差异均不显著(P>0.05)。综上所述,轻音乐可通过提高奶牛血液中γ-氨基丁酸含量,促进生长激素的分泌,降低皮质醇、五羟色胺的含量,稳定奶牛情绪,从而降低奶牛应激反应,提高产奶量。

| Abstract: | This experiment was conducted to study the effect of light music on milk yield and serum hormone levels of dairy cows.Thirty two healthy Holstein dairy cows with similar milk yield,age,parity and lactation were randomly divided into two treatments and 16 cows in each treatment.Playing light music for 2 h at every feeding time in experimental group,20 classical piano (Richard Clayderman) of light music was selected,the control group was routine feeding.The pre-test period lasted for 7 days and the trial period lasted for 60 days.The milk yield and blood samples were determined every 10 d.The results showed that the milk yield in experimental group was significantly higher than that in control group at 10 and 40 days (P<0.05),the milk yield in experimental group was higher than that in control group at 20,30,50 and 60 days,but the difference was not significant (P>0.05).In the whole experiment period,the milk yield in experimental group was extremely significantly high than those in control group (P<0.01),which increased by 1.72 kg.In the whole experiment period,light music could increase the serum γ-aminobutyric acid,growth hormone levels,and reduce the serum cortisol,serotonin levels,but the difference was not significant (P>0.05).In conclusion,light music could reduce stress and improve milk yield of dairy cows through increase the serum γ-aminobutyric acid level,promote the growth homone secretion and reduce the serum cortisol and serotonin levels. |
