Rearing systems for herbivores are to be based on maximum use of pasturage according to the availablity of pastures in the different periods of the year. At least 60 % of the dry matter in daily rations is to consist of roughage, fresh or dried fodder, or silage. Nevertheless, the inspection authority or body can permit a reduction to 50 % for animals in dairy production for a maximum period of three months in early lactation.
