Extract

NIRS has proved to be a rapid, accurate method of evaluating grass silage quality parameters using dried, milled samples. Recent research by Park et al., (1996) has shown that undried silage can be used to accurately estimate a wide range of chemical and biological parameters. The digestibility and degradability fractions of silage are important indicators of silage nutritive value. This study was undertaken to further explore the potential of NIRS as a means of predicting a range of digestibility and degradability components of undried grass silage.
