AMINO ACID CONTENT IN SOYBEAN MEAL

摘要

Soybean meal (SBM) serves as the main amino acid source in livestock feeds. It represents over 50% of the world's total production of protein meals. USA, Brazil, Argentina, India and China are the major producers of SBM, which can be of variable quality. As a consequence, quality control of incoming raw materials is essential because origin, farming, genetics and processing can strongly influence amino acid contents. Degussa analyses thousands of feed ingredient samples year by year. More than 550 assays were made for SBM alone, which represents samples from the most important SBM producing countries (Table 10.1). Analyzing this new set of SBM and a wide range of other important raw materials reveals differences compared to those published in various tables. These changes in raw material quality required updates to the regression equations for estimating amino acid contents based on crude protein levels. These new amino acid data sets and regression equations ensure that customers keep pace with the recent trends in feed ingredients and use the most precise information for the essential nutrients they contain.
