Colorimetric Determination of Protein in Feed and Forage Crops1
- Arnold J. MacKenzie and
- Eugene R. Perrier2
A colorimetric method using Orange G dye for the determination of protein in feed and forage crops is described. With each of six crops tested, a good correlation was found between Kjeldahl nitrogen percentage and the dye-binding characteristics of the plant proteins. The method is reproducible, rapid and easily adapted to a simplified routine operation.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
