Study Shows Cows Produce More Milk Under LED Lighting
Oklahoma State University monitored milk production among cows that were being milked under LED versus fluorescent lights. The study was originally started because farmers and researchers wanted to make sure that cows were unaffected by the change. The results were surprising, however - the cows actually produced 6% more milk than under the original lights.
One theory: LED lights reduce stress, making for more contented and productive cows.
The results astounded the study’s authors and those backing the research, including the National Rural Electric Cooperative Association.
They were expecting further insights into the lights’ energy savings and how they performed overall, including their durability on a working farm. Milk production was being tracked because of concerns the LED lights could harm the animals by, for instance, interfering with their feeding. A drop in milk production would signal a problem.
Instead, the average cow delivered an extra half gallon of milk per day.
