Offered Papers Theme A: Efficient Production from Grassland
Description
Warm-season (C4), the most common forage for beef production in much of the U.S.A., although having a higher productivity than temperate forages are of a lower quality. Current feeding standards (NRC, 1996) have adapted the Cornell Net Carbohydrate and Protein System (Sniffen et al., 1992) to more accurately characterize forage quality. As these procedures are tedious, data is limited on genetic and management factors influencing quality parameters in C4 species. The objective of this research was to determine if near-infrared reflectance spectroscopy (NIRS) could be used to predict the various N fractions in three C4 grasses.
