Research to determine the digestibility of amino acids in samples of regular and organic corn and soybean meal was reported in the Canadian Journal of Animal Science.  The experiment involved a total of 560, 14 day old male broiler chickens, 10 birds/treatment, and seven semi-purified wheat starch-based diets. Treatments compared imported and local sources of corn and soybean meal.  Results indicated only a few differences in the amino acid digestibility, primarily in non-essential amino acids.  The general conclusion was that the utilization of amino acids in conventional and organic feedstuffs was comparable.
