Nutritive value of papyrus (Cyperus papyrus, Cyperaceae), a tropical emergent macrophyte

Abstract

Papyrus (Cyperus papyrus, Cyperaceae) covers large areas in tropical African wetlands. Analysis of its nutritive value has revealed that crude protein is higher in umbels than culms. Ruminai dry matter digestibility of papyrus is, however, higher in culms than umbels. Both the crude protein and ruminai dry matter digestibility decrease with increasing age of the plant. Values for crude protein and ruminai dry matter digestibility are similar to those reported for the range grasses that constitute the greatest percentage of forage in East Africa. In general, papyrus has some grazing potential and could be used as fodder especially in the dry season when other forage is scarce and of low nutritive value.

Zusammenfassung

Der Futterwert von Papyrus (Cyperus papyrus),einem tropischen Macrophyten. Papyrus (Cyperus papyrus,) bedeckt im tropischen Afrika grosse Feuchtgebiete. Futterwertanalysen ergaben, dass der Gehalt an Rohprotein in den Dolden höher als in den Sprossen ist. Der verdaubare Anteil der Trockenmasse von Papyrus ist für Wiederkäuer jedoch in den Sprossen höher als in den Dolden. Die Verdaubarkeit von Rohprotein wie auch der Trockenmasse sinkt mit steigendem Alter der Pflanze. Die Werte für Rohprotein und verdaubare Trockenmasse sind ähnlich denen, die für die Hauptfuttergräser semiarider Gebiete in Ostafrika angegeben werden. Insgesamt besitzt Papyrus einiges Potential für Beweidung und könnte, besonders in der Trockezeit, wenn anderes Futter rar und von geringem Nährwert ist, verfüttert werden.
