Note to readers, attached is the completed final report for FNE00-318.
Illuminating pastures at night increased my milk production between 2.4 and 5.8 pounds per cow per day. I have little investment in the lights and movement of lights. This practice provides the most benefits during hot months and in the fall when the days become shorter. These lights can also be used in the barn when the power is off. I always used them while installing my new milking parlor this past fall.
