【摘要】：试验旨在探讨莫扎特音乐、轻音乐、原创音乐对奶牛泌乳及抗氧化性能的影响。选用产奶量、年龄、胎次、泌乳期相近的荷斯坦泌乳牛64头,随机分成4组,即莫扎特音乐组、轻音乐组、原创音乐组及对照组,每组16头。试验组早、中、晚3次各播放音乐2h,对照组无音乐播放。正试期当天起(0d),每隔20d测定单产奶量并采集血样1次,测定血液中总抗氧化能力(T-AOC)、超氧化物歧化酶(SOD)及谷胱甘肽过氧化物酶(GSH-Px)活性及丙二醛(MDA)含量。预试期7d,正试期60d。结果表明,试验第20天,轻音乐组、莫扎特音乐组奶牛产奶量均显著高于对照组(P0.05),轻音乐组、莫扎特音乐组、原创音乐组奶牛血清中SOD含量均显著高于对照组(P0.05),轻音乐组、莫扎特音乐组奶牛血清中MDA含量均显著低于对照组(P0.05),轻音乐组、莫扎特音乐组奶牛血清中GSH-Px活性均显著高于对照组(P0.05);试验0~60d,轻音乐组、莫扎特音乐组奶牛血清中T-AOC水平均显著高于对照组(P0.05)。综上所述,轻音乐、莫扎特音乐均有提高奶牛泌乳量的作用趋势,原创音乐对奶牛泌乳性能无显著影响;轻音乐、莫扎特音乐、原创音乐均有提高奶牛机体抗氧化能力的趋势。
[Abstract]:The purpose of the study was to investigate the effects of Mozart music, light music and original music on milk and antioxidant properties of dairy cows. Sixty-four Holstein lactating cows with similar milk yield, age, birth order and lactation period were randomly divided into 4 groups: Mozart music group, light music group, original music group and control group, with 16 in each group. The experimental group played music 3 times each for 2 h, while the control group did not play music. The milk yield was measured every 20 days and blood samples were collected. The total antioxidant capacity (T-AOC), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) activity and malondialdehyde (MDA) content were measured. The pretest period was 7 days and the current test period was 60 days. The results showed that the milk production of light music group and Mozart music group were significantly higher than that of control group (P 0.05), light music group, Mozart music group and original music group were significantly higher than that of control group (P 0.05) and light music group (P 0.05) on the 20th day of the experiment. The serum MDA content of the Mozart music group was significantly lower than that of the control group (P 0.05). The serum GSH-Px activity in the light music group and the Mozart music group was significantly higher than that in the control group (P 0.05), and the activity of GSH-Px in the light music group was significantly higher than that in the control group 60 days after the experiment. The serum T-AOC level in Mozart group was significantly higher than that in control group (P 0.05). To sum up, light music, Mozart music have the effect trend of improving milk production, original music has no significant effect on milk performance, light music, Mozart music, original music have the trend of improving the antioxidant ability of dairy cows.
