Hans-Pieter Sieber said his 700 cows sleep on water beds and are regularly seen by an animal psychologist to keep morale high, The Independent reported Tuesday.

Sieber said his cows vastly outperform cows on other farms when it comes to daily milk production.

"If you give the cows comfort they are more disposed to help out," he said. "Normal milk doesn't have much taste or smell. That's why we started this method."

Sieber said scientists at the Alcorcon Hospital in Madrid are testing the milk for special properties that could benefit patients with digestive problems.
