【摘要】：试验研究音乐对犊牛生长性能、应激及免疫的影响,以期为犊牛的福利养殖提供理论依据。试验选取6~10日龄身体健康、体况相近的荷斯坦母犊牛12头,随机分成对照组(不播放音乐)、音乐组2组,每组6个重复。每天上午8∶00~11∶00和下午的14∶00~17∶00给音乐组的犊牛播放舒缓型音乐《寂静山林》,音乐的音量为50~60dB;对照组除了不播放音乐,在同等条件下饲养。结果显示,音乐组犊牛的平均日采食量、平均日增重、体高增加量显著增加(P0.05),在试验第14天,两组间唾液皮质醇、α-淀粉酶、免疫球蛋白A、免疫球蛋白G含量差异不显著(P0.05)。在试验第28天,音乐组犊牛唾液唾液皮质醇含量显著降低、免疫球蛋白A含量显著升高(P0.05)。结果表明,音乐提高了犊牛的生长性能,降低了犊牛的应激激素,提高了免疫水平。
[Abstract]:The effects of music on the growth performance, stress and immunity of calves were studied in order to provide theoretical basis for the welfare breeding of calves. They were randomly divided into two groups: the control group (without playing music) and the music group (n = 2). Six repeats in each group. 8: 00 in the morning, 11: 00 in the morning, and 14: 00 in the afternoon at 17: 00, playing soothing music to the calves of the music group, "Silent Mountain Forest." The volume of music is 50 ~ 60 dB; The results showed that the average daily intake, average daily gain and body height of the calves in the music group increased significantly (P 0.05) on the 14th day of the experiment. There was no significant difference in salivary cortisol, 伪 -amylase, immunoglobulin A and immunoglobulin G between the two groups. The results showed that music could improve the growth performance of calves, decrease the stress hormones of calves, and improve the immune level of calves.
