Long Day Lighting
Long Day Lighting is when you manage your barn’s lighting to operate on a “Long Day Photoperiod” so that lights are on for 16 to 18 hours daily and operating with 15 to 20 foot-candles. Alternatively for 6 to 8 hours the barn is provided with complete darkness, less than 1 foot-candle. While many barns provide night lighting – research shows that cows can find their away around in the dark.
Research Results from Long Day Photoperiod:
- Lactating herd will respond in about 2 to 4 weeks and average milk production increase averaged 8 to 10%
- Livestock will respond with an increase of dry matter intake.
- Young livestock will mature faster, increased growth and reproduction.
- First lactation cows are more productive and cycle back into calf with ease.
