2013 Feed Ingredient Analyses
Each year Evonik Industries compiles a comprehensive report characterizing the amino acid content of the new U.S. corn and soybean crops. This year the report was expanded to include samples of corn distillers grains with solubles since this feed ingredient is being used U.S. swine and poultry diets. Samples of the feed ingredients are supplied to the Evonik Health Nutrition group by the feed formulator and the laboratory analyzes the three ingredients and reports values for the various geographical regions that supply the feed industry. The mean values for these three feed ingredients are shown in the following table.

2013 Composition of Corn, Soybean Meal and Distillers Dried Grains with Solubles (*)
Chart 1
(*) All values are expressed as percentages adjusted to 88% moisture; SD is the standard deviation of the mean; CV is the coefficient of variation, a measure of relative variation; and DC is the digestibility coefficient for swine and poultry, respectively.

While these values vary slightly from ingredient analyses published by other groups, the analyses show major differences between these three feed ingredients. Please note the differences in crude protein levels, total amino acids. digestible amino acids for both swine and poultry, and especially in the amount of variability within the three feed ingredients. Soybean meal is an excellent source of crude protein and digestible amino acids that is consistent between lots obtained from production areas ranging from North Carolina to Nebraska, and from North Dakota to Mississippi.

Also, reported were values for the past five crop years (next table). Most importantly, the composition values for last year’s soybean meal (2012) are equal to, or greater than, the values for the past four years.
