摘要

Introduction Accuracy/precision of crude protein assay (CP) iscritical for the trade of soybean meal (SBM) and feedformulation. Past experience indicated that the CPassay variation in China could be very large and farbeyond AFCO Analytical Variation (AV%, previouslyPermitted Analytical Variation or PAV%). On CP testprocedures recently there has been a saying that theLeco combustion method was more accurate than theclassical Kjeldahl procedure.
