Details of project
Traditionally the simple measurement of specific weight (weight of a litre of grain) has been used by cereal producers and animal feed millers as an indication of cereal nutritive value and certain generalizations are made depending on this value. For example, grain with a low specific weight is thought to contain a higher level of protein, fat and fibre and a lower level of starch and generally thought to be of lower nutritive value than grain of higher specific weight value. However, there is substanial evidence to suggest that specific weight is not an accurate predictor of chemical composition or nutritive value.
Research published in the Home Grown Cereal Authority (HGCA) Report Number 260 reported that there was a lack of relationship between specific weight of wheat and its nutritive value in relation to poultry, pigs and ruminants. Despite this, grain producers and feed millers still use specific weight as an indicator of grain nutritive value. Consequently, there is a need for an alternative, accurate and rapid means of assessing cereal quality.
