NIRS predicted WSC

silages may not be representative of
what we see in today's samples. This
compromises the accuracy of the
predictions for current samples.
Sugar content is simply one example, but it highlights the significance
of maintaining up-to-date calibration
databases behind the predictions.
When having samples analyzed,
there are some useful things to
consider:
■ Whether the calibration used is
specific for the forage in question
■ The number of samples from a similar geographical region are in the
database from the past two years
■ Obtain a wet chemistry analysis
for important analytes, such as
protein, and compare the values
against the NIRS counterpart
■ The methodology used to determine digestibility value
■ The origin of the calibration -
significant geographical variation
in samples can and does occur

Wet chemistry % WSC

The graphic shows near-infrared spectroscopy prediction of watersoluble carbohydrate (WSC) from one specific calibration database. The
"dotted line" indicates a "best fit" line; the solid line represents where
data should lie if the predicted and the wet chemistry completely agree.
In summary, NIRS has become
the analytical method of choice
over traditional wet chemistry in
the analysis of many feed materials,
particularly forages. However, not all
NIRS analyzes are the same behind
the scenes, and there are several important points to bear in mind when
having samples analyzed, including the type, age and origin of the

samples used for calibration, as well
as methodology used to derive the
prediction equations. ■
