Extract

Whole crop wheat and maize silages are becoming more widely used as additional winter forage for ruminant animals Whole crop wheat and maize forage can be produced with greater nitrogen efficiency than grass swards (Aarts et al., 1992) and it has been shown that forage maize inclusion in grass silage based diets has resulted in increased DM intake, milk yield and milk protein content (Keady et al., 2002). Consequently a robust, cost-effective method to accurately characterise the feeding value of these forages is required. Previous research at this Institute (Park et al., 1998) has shown that NIRS can be used successfully to estimate the chemical and biological parameters of grass silage. The objective of this study was to examine the potential of NIRS to predict the chemical composition of whole crop wheat and maize silages.
