【摘要】：本研究旨在探讨3种不同类型的轻音乐对奶牛泌乳性能及能量代谢指标的影响。选用泌乳量、年龄、胎次、泌乳期相近的荷斯坦泌乳牛64头,随机分成4组,即轻音乐A(速度60 bmp的钢琴轻音乐《梁祝》,音色圆润)组、轻音乐B(速度70 bmp、小提琴演奏的泌乳牛情绪调控曲,音色明亮)组、轻音乐C(速度60 bmp、钢琴演奏的奶牛泌乳性能调控曲,音色圆润)组和对照组,每组16头。3个轻音乐组分别于早、中、晚3次挤奶前各播放音乐2 h,对照组无音乐播放。预试期7 d,正试期60 d。正试期每隔20 d测定泌乳量,并采集血样和乳样。结果表明:1)试验20、40 d及1~60 d,轻音乐A组、轻音乐B组和轻音乐C组奶牛干物质、有机物、中性洗涤纤维、酸性洗涤纤维、粗蛋白质和粗脂肪摄入量均高于对照组。2)试验1~60 d,轻音乐C组奶牛泌乳量、4%标准乳产量显著或极显著高于对照组(P0.05或P0.01)。3)试验1~60 d,轻音乐B组和轻音乐C组血液谷草转氨酶、丙氨酸转氨酶活性显著低于对照组(P0.05),轻音乐C组血液谷丙转氨酶、乳酸脱氢酶活性显著低于对照组(P0.05)。4)试验40、60 d,轻音乐C组奶牛血液甘油三酯含量显著高于对照组(P0.05);试验1~60 d,轻音乐C组奶牛血液葡萄糖含量显著高于对照组(P0.05);整个试验期,轻音乐A组、轻音乐B组和轻音乐C组奶牛血液游离脂肪酸含量均低于对照组,但差异不显著(P0.05)。综上所述,3种轻音乐均有提高奶牛营养物质摄入量、刺激泌乳及改善奶牛能量代谢指标的作用趋势;70 bmp的轻音乐较60 bmp的轻音乐对奶牛泌乳更为有利;与音色明亮的轻音乐相比,奶牛对音色圆润的轻音乐敏感性更高,音色圆润的轻音乐更能提高奶牛泌乳性能。
[Abstract]:The purpose of this study was to explore the effects of 3 different types of light music on milk performance and energy metabolism in dairy cows. 64 cows were randomly divided into 4 groups: light music A (60 BMP of piano music < Liang Zhu > tone color), light music B (speed 70 BMP, violin performance) The milk cow's emotion control tune, the tone color bright) group, the light music C (speed 60 BMP, the milk performance control curve of the cows on the piano, the tone color round) group and the control group, each group of 16.3 light music groups in the early, middle, and late 3 times before milking 2 h, the control group is 7 d, the 60 D. positive period of the positive test period is measured every 20 d intervals. The results showed: 1) test 20,40 D and 1~60 D, light music A group, light music B group and light music C Group dairy cow dry matter, organic matter, neutral detergent fiber, acid washing fiber, crude protein and crude fat intake higher than the control group.2) 1~60 D, light music C group milk production, 4% standard milk production significant Or significantly higher than the control group (P0.05 or P0.01).3) test 1~60 D, light music B group and light music C group blood glutamic grass transaminase, alanine aminotransferase activity significantly lower than the control group (P0.05), light music C group blood glutamic prop aminotransferase, lactic dehydrogenase activity significantly lower than the control group (P0.05).4) experiment 40,60, light music group cow blood glycerin three The content of ester was significantly higher than that of the control group (P0.05); the blood glucose content in the blood of 1~60 D and the light music C group was significantly higher than that of the control group (P0.05). The content of free fatty acids in the blood of the light music A group, the light music B group and the light music C group was lower than the control group in the whole test period, but the difference was not significant (P0.05). In summary, 3 kinds of light music all improved milk. Nutrition intake of cattle, stimulating milk secretion and improving the energy metabolism index of dairy cows; 70 BMP light music than 60 BMP light music is more favorable for dairy cow lactation; compared with bright light music, cows are more sensitive to sound and light music, and light and round music can improve milk lactating performance.
