"When it comes to feeding value, it is the content of the essential amino acids that counts."

Soybean Quality

Why is a better measure of soy quality needed?

Crude protein percentage alone is only an estimate of the total amino acids based on the level of nitrogen detected; it tells you nothing about the quantity of each amino acid or the balance of the essential to non-essential amino acids. When nutritionists and producers know the Critical Amino Acid Value (CAAV) in feed ingredients, they know the true value in the feed. There are quantifiable economic benefits to using high CAAV meals in feed formulations, and there are significant environmental benefits to utilizing high CAAV soybeans. A diet using meal from a lower crude protein soybean with a naturally higher CAAV can contribute to a healthier animal and cleaner environment.
