NEW YORK, July 20 (Xinhua) -- When we human beings are in a good mood, we work more effectively and produce better products. This also applies to cows.

Researchers at the University of Wisconsin-Madison in the United States are trying a new method to make cows produce better milk -- giving them regular injections of the hormone serotonin, a chemical messenger that makes both humans and animals feel happy, Quartz reported.

Professor Laura Hernandez and her team gave 24 cows the serotonin treatment, which raised the calcium level in the cows' blood, thus making their milk more calcium-rich.

Although the milk is more nutritious, according to Quartz, the milk yield is still normal. Besides, since the team only tested the treatment on two breeds, it will still take some time and more samples before the treatment can be widely used.
