Leaves are an important resource of feed stuff for many ruminants (e.g. browsing in extensive grazing systems with access of animals to shrubs and trees). The contents of minerals and trace elements of leaves from trees and shrubs are not known. In 2002, leaves of about 30 northern German (Schleswig-Holstein) shrubs and trees were analysed for minerals and trace elements. The results show that the leaves of the different shrubs have different values. Leaves can be an important source of minerals and trace elements for ruminant diets
