Photoperiod manipulation, also known as long-day lighting, has been well documented to increase milk production in lactating dairy cows during relatively short time frames in controlled research settings. Dairy producers regularly request information relative to the design of a photoperiod lighting systems for their barns. Many variables exist and need to be investigated in order to perform a prudent design. This paper discusses each design variable and how it relates to the design and maintenance of the resulting lighting system. Proposed installation options are presented for several barn configurations based on their contemporary building dimensions. Suggested lighting system maintenance schedules are provided based on initial design assumptions and their impacts are discussed.
