Extract

Short chain fatty acids, produced from the fermentation of feedstuffs, form the ruminant’s primary energy source, as well as being precursors of glucose, protein and milk constituents (Dijkstra et al., 2000). The analysis of rumen fluid to estimate short chain fatty acids involves the addition of internal standards and analysis by gas chromatography. NIRS has been shown to have the potential to accurately and rapidly evaluate fresh silage chemical and biological parameters, including short chain fatty acids (Park et al., 1998). This study was undertaken to evaluate the potential of NIRS to accurately estimate the chemical composition of rumen fluid when a range of diets were fed to fistulated steers.
