Milk Increase

Cows produced an extra half gallon more milk under LED lights says study completed by Oklahoma State University

LED lights are becoming increasingly well known for their energy saving and eco-friendly benefits, with users being able to save significant amounts on their lighting bills when compared to other forms of lighting such as fluorescent and incandescent lights. LED bulbs are to be found in a wide variety of different applications, the latest of which is an extensive field study involving dairy farmers switching to LED lights in their milking sheds.

The research carried out by Oklahoma State University was originally commissioned to look at the performance of the LED lights overall, including electricity consumption and increased durability when installed on a working farm. As a side note, researchers monitored milk production to see the effects that the LEDs had on the livestock to ascertain whether the LED lights would harm the animals and affect their feeding. A reduction in the production of milk would indicate a problem.

However, a startling discovery has come to light, milk production actually increased following the switch from fluorescent to LED bulbs. In fact, the test herds produced an average of 6% more milk under LED light bulbs, equivalent to an extra half gallon per cow per day! The results amazed researchers and farmers alike and they are now looking into exactly why this would happen, as this could mean a revolution in dairy production.

One theory centres around the fact that LED lights reduce stress in the animals, making the cows more productive. The light given off by the new LEDs is a less harsh, more natural light than the previous fluorescent bulbs, offering a far more appealing environment for the livestock.

Dairy farmers can certainly benefit from switching to LED light bulbs in terms of the environmental and energy-saving benefits. LEDs use up to 90% less electricity than other standard light bulbs and have a much improved life span – the average LED bulb lasts around 50 000 hours. An added advantage for installation on a working farm is the increased durability offered by LED bulbs, they are not subject to degradation from heat or vibration and therefore are far less prone to failure.

Ecopower LED can provide dimming capabilities that maximize the farmers investment by providing precisely the right amount of light required not to mention a 60%+ reduction in energy consumption.
