The objective of this study was to evaluate the inclusion of de-oiled dried distillers grains plus solubles (DDGS) in the diets of laying hens. One-hundred sixty, 20-wk old Bovan White Leghorn Hens were housed 4 per pen in 40 pens with 10 replicates per treatment. Hens were randomly assigned to pens in a randomized complete block design consisting of treatments, (control, normal fat DDGS, medium fat DDGS, and low fat DDGS). An inclusion rate of 20% DDGS with varying percentages of fat: normal (11.20%), medium (7.30%), and low (5.62%) were included in a standard corn/SBM layer diet. A corn/SBM diet without added DDGS acted as the control. All hens were given ad libitum access to feed and water. Response variables included: egg production, egg weight and feed intake, all recorded weekly with hen body weight observations recorded on wk 0, 8, and 13 with the study lasting a total of thirteen weeks. There was no significant effects of treatment with respect to egg production, egg weight, feed intake and hen body weight (p>0.05). Varying the percentage of fat in 20% DDGS diets fed to laying hens does not affect egg production parameters.
