Essential Amino Acids
Soybean quality has traditionally been measured by crude protein content. However, recent research shows that measuring the presence and balance of essential amino acids is a better way to assess soybean quality.
Crude protein percentage is an estimate of the total amino acids based on the level of nitrogen detected and does not equate to higher protein quality or better nutritional value for feeding livestock. Because feed rations are formulated based on the amino acid content, its logical that a critical amino acid value (CAAV) is a better way to measure soybean quality. When nutritionists and producers know the CAAV, they know the true value in the feed.
