AgriLux Photoperiod Control Systems

By AgriLux

Last reviewed: December 2025

Photoperiod control systems automate long-day and short-day lighting programs for dairy cattle, optimizing production and dry cow management.

Overview

Photoperiod control systems automate lighting schedules to provide optimal day length for different groups of dairy cattle, supporting both lactation and dry cow management through programmed light/dark cycles.

Light Management Protocols

Long-Day Lighting (Lactating Cows)

  • 16-18 hours of light
  • 6-8 hours of darkness
  • 15-20 foot-candles intensity
  • Increases milk production 5-16%
  • Short-Day Lighting (Dry Cows)

  • 8 hours of light
  • 16 hours of darkness
  • Prepares for improved next lactation
  • Enhances immune function
  • Control System Features

    Timer Functions

  • Daily schedules
  • Multiple zones
  • Dawn/dusk simulation
  • Override capabilities
  • Sensor Integration

  • Natural light monitoring
  • Automatic adjustment
  • Weather response
  • Zone Control

    Separate programs for different animal groups.

    Implementation

    Zone Planning

  • Lactating cow areas: long-day
  • Dry cow areas: short-day
  • Transition considerations
  • Light Level Verification

    Measure foot-candles at cow level.
