Long-day Energy Efficient lighting for dairy operations(26519)

Cornell Coop Ext Livingston County

Background

Utilizing long-day (sixteen (16)-hour) photoperiod (LDPP) to improve milk production efficiency may increase the profitability and competitiveness of the dairy industry in New York State. There is some evidence to suggest that exposure of dairy cows to long-day (sixteen to eighteen hours) lighting leads to 5% to 16% increase in milk production (as much as five pounds more milk per day, per cow) without affecting milk composition, increasing overall fat and protein yield. The long photoperiod is thought to stimulate concentrations of prolactin and growth factors associated with improved mammary growth and function in cows, without adversely affecting cow health.

Project Description

The objective of this study is to quantify the relationship between long-day (16-hour) lighting and milk production in dairy cows, and determine which lighting systems (T8 fluorescent (T8), or light-emitting diode (LED)) provide maximum milk production and quality while maximizing energy efficiency.

Benefits

The results are expected to inform dairy operators of the most energy efficient and effective lighting for improving milk yield and quality.
