ABSTRACT
In recent studies on the grazing management of pastoral herds it was shown that traditional systems of husbandry have evolved in which the provision of a varied fodder diet to stock is a predominant aim. Herdsmen living in close touch with their savannah environment take continuous advantage of the seasonal availability of all fodder sources and adapt their management and adjust their movement to this ever-changing supply situation. Over centuries they have accumulated detailed knowledge of the fodder potential in their regions of orbit and know the grazing habits and fodder preferences of their stock (van Raay and de Leeuw, 1970,1974).
