Grass Silage

The new metabolisable protein system (AFRC, 1992) introduces the requirement to distinguish between the energy in feeds which is fermentable (available for microbial growth) and that which is non-fermentable (available to the host animal; NFE). Fermented forages such as grass silage (GS) may contain substantial amounts of fermentation acids (FA) (volatile fatty acids (VFA) and lactic acid (LA)) and therefore, contain a considerable proportion of NFE. The aim of the present experiment was to investigate the use of near infrared reflectance spectroscopy (NIRS) as a rapid method for predicting the FAs in fresh (undried) GS.
