Brewers Wet Grains-Composition Variability

Researchers at Rutgers University sampled daily trailer shipments of wet brewers grains from a large brewery over a twelve-month period.  Samples were composited weekly and analyzed by a commercial laboratory.  They reported the following data for the 48 samples:



The researchers concluded that the nutrient content of wet brewers grains from a single supplier varies and simply analyzing or monitoring dry mater content will not be sufficient when formulating diets.
