Today many hog diets can consist of 20% distilled dried grain with solubles. DDGS, if mixed properly, can reduce feed costs while not impacting growth performance. Although, there still remains some variability in DDGS as lysine content comes in wide ranges. Color is one determinant of lysine content with dark colored grains having less lysine and light colored grains having more lysine.This study sets out to explore techniques and use of co-products color for predicting the nutritional value of DDGS for swine, particularly focusing on lysine. Samples were collected from ethanol plants in Ontario that provide DDGS. Samples were tested for, among other things, dry matter, organic matter, crude protein, lysine, fat, and each sample was given a color score from 1-100 (0=black, 100=white). The results showed that there was a considerable amount of variation in the nutrient profiles of the samples. The limited number of samples were able to be made into a model that can rapidly estimate lysine content and predicted and available amino acids. One observation made was that lysine did not move with protein content and other amino acids especially when the lighting score was low (below 45).
