Herbage Yield and Quality of Threadleaf Sedge

Abstract

An investigation of herbage yield, crude protein, and in vitro dry matter disappearance (IVDMD) levels of ungrazed threadleaf sedge (Carex filifolia Nutt.) was conducted over a 2-year period in western Nebraska. Threadleaf sedge contributed approximately 80% of the total herbage production on the study site. Crude protein varied from over 18% in late April to 5% or less in February. Levels of IVDMD varied from 69% in May to 51% in March. Levels of these quality factors were higher than those for most grasses throughout the year.
