Characterizing feed at a cellular level
Traditionally, conventional
chemical analysis has been used to determine feed composition and to predict nutritive
and energy values. Although this technique can identify the total chemical composition,
it cannot detect intrinsic structures, and it fails to link structural information
to chemical information.
Peiqiang Yu of the University of Saskatchewan
in Saskatoon, Canada, has reviewed the use of synchrotron-based Fourier transform
infrared microspectroscopy to characterize feed inherent structures at a cellular
level and to relate the data to feed quality, nutritive value and digestive behavior
in animals. This technique can provide information about tissue composition, structure,
chemistry and environment simultaneously.
In one study, researchers focused mid-infrared
synchrotron light onto samples of feed and used absorbance spectra to identify chemical
compounds. In particular, they used the approach to reveal molecular-chemical features
of protein secondary structures in flaxseed tissue. The technology allows researchers
to view not only visible images, but also the distribution and concentration of
biological components in various feeds.
Yu notes several implications of the
studies, including the ability to chemically define intrinsic structures of feed
and to compare feeds according to their spectroscopic features. He believes that
the synchrotron-based technology can be used to establish relationships between
the inherent structure and nutritive value of protein, and that it will contribute
to molecular-structural-chemical research. (A
