Volatile
Fatty Acids (VFA)
Agri Analysis, Inc. offers Volatile Fatty Acids testing on our NIRS.
Fermentation analysis is available for evaluating silage
quality. Analyses commonly included in silage fermentation are pH,
lactic, acetic, propionic, butyric acids, ammonia, and
ethanol.
Data from a fermentation analysis can tell us whether an
excellent, average or poor fermentation occurred. The
fermentation a crop goes through in most cases can be influenced by
two sets of factors. Fermentation factors that occur due to
nature would include moisture content, buffering capacity and sugar
content. Managerial factors would include proper moisture
content, silo packing speed, silage pack density, chop length and
proper usage of storage facilities.
