The aim of the project is to study effects of LED-light on milk production and activity in dairy cows. The main hypotheses are that LED light allows maintained cow activity and milk production with less energy used for illumination, and that LED-light makes it possible to apply a dark period during the natural night without decreased milk yield. Two experiments will be included to identify suitable wavelength and light intensity day and night. Activity, milk yield and hormones that are affected by light and that regulate milk production will be determined. The results from the two experiments will be validated on 6-10 commercial farms. The project group includes scientists at SLU, in Denmark and Norway, the company Heliospectra AB and Arla Foods Amba.
The expected output of the project is a better understanding of circadian rhythm in cows and recommendations for LED-light in dairy barn for lowered energy use at maintained or higher activity and milk production.
Syftet med projektet är att studera effekten av LED-ljus på mjölkproduktion och aktivitet hos mjölkkor. De
huvudsakliga hypoteserna är att aktivitet och mjölkmängd kan bibehållas med lägre energiåtgång för belysning om lysrörsbelysning ersätts av LED-ljus, samt att LED-ljus möjliggör en mörk period under den naturliga natten utan att aktivitet eller mjölkmängd minskar. Två försök kommer utföras för att identifier lämplig våglängd och ljusintensitet för dag och nattbelysning. Aktivitet, mjölkmängd och hormoner som påverkas av ljus och som reglerar mjölkbildning kommer mätas. Resultaten från försöken kommer valideras i tio kommersiella besättningar. I projektgruppen ingår forskare vid SLU, i Danmark och Norge, företaget Heliospectra AB och Arla Foods Amba.
Projektet kommer bidra med ökad förståelse för dygnsrytm hos kor samt leda till rekommendationer för LED-ljusprogram i stallbyggnader för mjölkkor för minskad energiförbrukning och bibehållen eller ökad aktivitet och produktion.

Young horses can develop cervical vertebral stenotic myelopathy and ataxia, known as "wobbler syndrome" and associated with loss of breeding value, reduced athletic potential and euthanasia. Some wobblers have osteochondrosis of their vertebral facet joints, but it is now known how this relates to …

The rollback of insecticides exposes Swedish horticulture to a multitude of pests. Targeted and sustainable innovations are sorely needed. Here we target several pests of fruits, onion, cabbage, beans and salad and aim to develop 1) species-selective lures using a novel olfactomics platform, 2) use …
