Cows are stimulated to produce more milk when they register longer days through their eyes and brain. Optimize your barn design with the right lighting and make your cows happy. Missing out on light can be depressing to cows and lead to less productivity. The lack of light slows down their metabolism, so create the best environment with the right lighting and create a natural rhythm for cows, making them more comfortable. This environment will have a positive impact on how much milk they make. In most stall barns, natural daylight is insufficient. Therefore, the interior barn lights need to also be on during the day. LED lighting provides the best high-energy efficiency solutions on for your barn with an astounding 100,000-hour operating life. To ensure consistent lighting, controls should be installed. Controls allow for a slow dimming process that transitions the cows from daylight to moonlight. Look at some of the products you can consider when designing your new barn lighting layout.
