Milk production by dairy cows is a very complex process. It is not only regulated by various hormones in the cow's body, but also affected by the cow's system. However, hormones in cows can actually be regulated by changes in the external environment, so listening to music to cows can indeed increase milk production. 1. Factors that affect the content of various hormones in the body.

You must know that various hormones in the body are affected by the external environment. To give a simple example, when a person is frightened, adrenaline will rise. When frightened, the human body will release adrenal cortical hormones, which will speed up the heartbeat and contract muscles, putting the human body in a state of excitement. It is a very primitive emergency response. In fact, it is the instinctive reaction of animals to quickly avoid danger.

Of course, cows, which are also mammals, have similar stress responses. It is worth mentioning that not all such stress responses are beneficial. For example, if you are frightened too much, your adrenaline will suddenly surge, and your muscle contraction will be greatly enhanced. If the blood vessels are compressed, it will cause insufficient blood supply and cause fainting. Therefore, the level of hormones in the body has a great impact on biology. 2. A superior living environment will make cows feel better.

Cows are also mammals, and they also have good and bad moods. Just like human work, the speed and quality of completing the same job under different moods are very different, because humans are not machines, and emotions have a great influence on a person's attitude. Of course, the same is true for cows. If a cow lives on a prairie with plenty of nutritious food, how can such a cow produce less milk than a cow living in a noisy factory? According to research, cows that listen to music produce three percent more milk than cows that don’t listen to music, under the same circumstances. Although it is only 3%, you must know that if it is a large ranch with tens of thousands of cattle, this 3% will increase the profit to another level.
