Research: Naturally Improve Cow Milk Production by up to 7% with Lighting

For dairy cattle farm managers, increasing milk production is essential for the success of their farm. While management practices such as proper nutrition and health management play a crucial role, lighting can significantly impact milk production as well. Our team recently conducted a in-depth research to support these words with numbers.

In this blog, we'll discuss by how much RUDAX lighting and a HATO light scheme naturally improve milk production of dairy cows according to our research.

The research

We've tested the RUDAX lighting solution in a research farm in China where we saw milk production improvements of 8%. To confirm these findings in a country with higher production numbers, our team conducted a two-year research study at a Dutch dairy farm with 100 cows, of which 85 in production.

Before situation

During the before situation, the farm used sodium lighting, with an average light intensity of 50 lux in the resting area and 70 lux in the feeding area. The lights didn't have sensors to regulate the light intensities, nor did they have dimming possibilities. The lights were on 24/7.

After situation

We installed 39 RUDAX led lighting solutions, which provided an average light intensity of 180 lux in the resting area and 120 lux in the feeding area. The RUDAX lighting had a CRI (Colour Rendering Index) of 83 with an average colour temperature of 4600K. A light sensor regulated the light intensity, and the RUDAX enabled 100-0% dimming. We used a HATO light scheme, using different colours to realise the best results.

Increased milk production

The 305-day production was taken into account, and the results showed that replacing sodium lights with RUDAX lighting and using the HATO light scheme naturally increased milk production. In the comparison group, the average increase was significant with +5.8 Kg per day (+17,5%). Since management changes and lactation numbers outside the target group also contributed to the increase in milk production, an estimated 20%-40% of the increase was caused by lighting.

This means that in the comparison group an estimated milk increase per cow of 1.2 – 2.3 Kg or 3.5% – 7% a day was realised only by the replacing of sodium lights by RUDAX lighting and using the HATO light scheme. As you can imagine, this had a significant impact on profits as well.
