Extract

Information on the rumen degradation characteristics of various feed fractions including nitrogen (N) and cell walls (CW) is gained largely through the use of the in sacco procedure. While various in vitro techniques have been applied there is an urgent need for the development of rapid methods for predicting aspects of feed degradation. Near infrared reflectance spectroscopy (NIRS) has been widely applied as an accurate and rapid method of analysis. In the present experiment the ability to predict in vitro CW degradability (CWD) characteristics of grass silage (GS) was investigated using NIRS.
