不同类型音乐对荷斯坦牛产奶量、乳成分及乳体细胞数的影响

Effects of Three Different Genres of Music on Milk Composition and Somatic Cell Counts of Chinese Holstein Cows

选取年龄、胎次、产奶量相近的荷斯坦泌乳牛80头,随机分成4组,每组20头。3个试验组每日分别播放哈萨克族音乐、贝多芬《第六田园交响曲》、维吾尔族音乐,对照组不播放音乐。结果表明:整个试验期内三个试验组的产奶量均低于对照组(P<0.05),哈萨克族音乐组、维吾尔族音乐组奶牛乳体细胞数均低于对照组(P<0.05、P<0.01);三个试验组的牛乳乳成分含量均较对照组高,其中哈萨克族音乐组的乳脂率极显著高于对照组(P<0.01)。在整个试验期内三个试验组间的产奶量差异均未达到显著水平(P>0.05);播放贝多芬《第六田园交响曲》使奶牛乳体细胞数有所提高(P<0.05),但作用时间有限;在试验第20天、40天哈萨克族音乐组的乳蛋白率、乳糖含量较贝多芬《第六田园交响曲》组高(P<0.05)。说明这三种音乐对奶牛产奶量均产生了负面影响,哈萨克族音乐对提高乳脂含量有显著作用,哈萨克族音乐和维吾尔族音乐对降低牛乳体细胞数有一定作用。

The objective of this study was to evaluate the effects of three different genres of Kazak music,Beethoven＂Sixth Pastoral Symphony＂and Uygur music on production performance,milk composition and somatic cell counts of dairy cows,in order to provide references for the application of music in the production of dairy cows.Eighty healthy Chinese Holstein lactating dairy cows with similar age,parity and milk yield were selected,and divided into 4 groups with 20 cows each group.The trial group daily playing Kazak music,Beethoven＂Sixth Pastoral Symphony＂and Uygur music,the control group with routine feeding.The results showed that,milk yield,somatic cell count in the three trial groups were lower than the control group during the whole trial period（P 〈0.05）.The milk composition of the three trial groups were higher than the control group,the milk fat content of the treatment of kazak music reached significant level（P〈0.01）.Milk yield of the three trial groups did not reached significant level during the whole trial period（P〉0.05）.The milk protein and lactose content of the treatment of kazak music was higher than ＂Sixth Pastoral Symphony＂in 20 days,40 days of trial period（P〈0.05）.In conclusion,the effects of three genres of music on milk production,milk composition and somatic cell count is limited.
