According to a study conducted by the University of Leicester, cows tend to produce 3% less milk when they listen to fast or loud music as compared to calm and soothing music. The study found that cows experienced stress when they were exposed to fast or loud music, which resulted in a decrease in their milk production. The research highlights the importance of creating a stress-free environment for cows, which plays a significant role in maintaining their productivity. Therefore, it is advisable to play calm and soothing music in the dairy farms to keep the cows relaxed and happy and to maximize their milk production.
