Light level and lighting regime
Light is an important factor in dairy farming when it comes to animal welfare. The light level and the duration of the day and night periods are very important factors. Scientific research shows that a light level of 150 to 200 lux and a day/night period of 16 hours of light (150 to 200 lux) and 8 hours of darkness 16L:8D (no night lighting) is optimal. This is to create a good and stable biorhythm for the dairy cow. Research has shown that a stable biorhythm has the following advantages:
• Improved fertility
• Reduced number of inseminations
• Reduced calving interval
• Improved milk production (6-15%)
• Fewer bone and joint disorders
• Reduced early culling of dairy cows
The same light level and day/night rhythm will also accelerate growth and development of young stock. For dry cows, a rhythm of 8 hours of light and 16 hours of darkness at 150 to 200 lux appears to be ideal.
An inappropriate light level or lighting regime may have consequences for the health, production or welfare of your animals. That is why you should always ask for advice before purchasing barn lighting. In a free and non-binding lighting plan we can show you all the advantages of a good and well-considered light level. In addition, our light fittings meet the criteria and assessment guidelines of the Sustainable Stockholding Criteria Benchmark and the requirements of the Dairy Farm Light Nuisance Agreement.
Light current of various fittings
Numerous types of light fittings are available for barn lighting. To make the most efficient use of lighting, it is recommended to check the light output (lumen) and wattage of a light fitting. The relation between these two variables is expressed in the energy efficiency lumen/watt ratio of the light fitting.
