Abstract

Management of lighting in dairy housing has recently received interest as a method to improve production. In addition, recent evidence suggests that photoperiod manipulation can be used to enhance disease resistance, especially during the dry period. As with any management approach, there are certain guidelines that require consideration for successful implementation. This review covers the biology of photoperiod responses in cattle, impacts on production and health, and suggestions for implementation.
