US soybean meal had higher levels of crude protein, greater protein solubility, higher levels of total lysine, methionine, cysteine, valine and isoleucine; and lower levels of total glutamic acid. Reactive lysine and available amino acids were generally higher for U.S. soybean and significantly greater than the India soybean meal.
This study will be continued and more samples analyzed. Greater numbers of samples will provide greater reliability in the average values of the various nutrients and will reduce the standard deviations for the values. With more samples, the differences between the means will become more evident.
