The effect of light music on lactation performance and blood neurotransmitters in cows
The purpose of this study was to investigate the effect of light music on the lactation performance and blood neurotransmitters of dairy cows.In the experiment,80 Holstein lactating cows with good health were randomly divided into 2 groups,namely the control group and the light music group,and 5 replicates were set in each group,with 8 heads in each replicate.The experimental group played Claude Debussy's classic piano piece"Moonlight"for 2 h before milking from 09:00 to 10:30 and 14:30 to 16:00 every day,while the control group had no music played,with a pre-test period of 7 days and a regular test period of 60 days.The results showed that,compared with the control group,the milk production of the light music group was significantly higher than that of the control group on the 20th,40th and 60th days(P＜0.05),and the milk yield of the milk group was increased by 6.70%,8.00%and 9.24%,respectively.The content of β-endorphins in the serum of dairy cows was significantly higher than that of the control group on the 20th,40th and 60th days of the test(P＜0.05),the content of neuropeptides in the serum of dairy cows was significantly higher than that of the control group on the 40th and 60th days of the test(P＜0.05),the content of glutamate in the serum of dairy cows was significantly lower than that of the control group on the 20th,40th and 60th days of the test(P＜0.05),the total serum protein content of dairy cows in the light music group was significantly increased on the 20th,40th and 60th days of the test(P＜0.05),and the serum urea nitrogen content of the light music group was significantly decreased on the 40th and 60th days of the test(P＜0.05).Studies have shown that light music can effectively improve the stress state of dairy cows and improve their lactation performance.
