Nutrient Variability in Distillers Dried Grains

University of Georgia researchers obtained twelve distillers dried grain samples from six processing plants in the Midwest. The samples were assayed for true metabolizable energy and available amino acids using rooster assay techniques. Results indicated marked variation between samples attributed to differences in processing procedures. They found the between- process plant variation was much greater than samples from the same plant. The researchers suggested that the nutritionist should analyze samples from new suppliers prior to using the distiller product in feed formulations..
