Fremgangsmåde til fremstilling af mælk eller mælkeprodukter, der har et højt indhold af melatonin

摘要

A method for the production of milk with increased melatonin content or a milk product made therefrom. The method comprises dividing the daily cycle of a female mammal into a daytime phase under a first light regime with a proportion of blue light and a night-time phase under a second light regime and milking the mammal at least once during the night-time phase in order to obtain milk with an increased melatonin content. For the second light regime there is used at least one light source which emits light in the wavelength range of 500 nm or above and substantially no light in the wavelength range below 500 nm.
