Extract

The feeding value of grass silage mainly depends on a combination of its intake potential and digestibility. Near infrared reflectance spectroscopy (NIRS) has been successfully used to predict the organic matter digestibility (OMD) of silage (Baker et al., 1994) and Steen et al. (1995) has demonstrated that this technique also offers a much greater potential for the prediction of intake than methods based on wet chemistry. The work reported by Steen et al. (1995) provided a large contemporary sample and data set suitable for exploring the full potential of NIRS for the prediction of both intake and OMD.
