N2 - Two experiments were conducted from 0 to 21 d of age and evaluated diets containing combinations of fine or coarse ground corn (557 or 1,387 μm, respectively), whole sorghum, 15% corn distillers dried grains with solubles (DDGS), or a prebiotic-type product containing yeast cell wall, lactose, citric acid, and other fermentable carbohydrates. In experiment 1, feed efficiency was decreased (P < 0.001) after the first week of age for broilers fed diets containing whole sorghum, whereas broilers receiving diets with 15% DDGS had increased feed efficiency (P < 0.03) compared with those receiving no DDGS. In the second experiment, BW gain was increased (P < 0.03) after the first week of age for broilers fed diets containing the prebiotic and DDGS compared with their respective controls. In experiment 1, the diet containing sorghum yielded the highest AMEn value (P < 0.03). In experiment 2, diets containing the combination of the prebiotic + DDGS yielded higher AMEn values (P < 0.004) at 7 and 21 d compared with diets containing no combination. The effects of diet on amino acid digestibility were generally small and inconsistent in both experiments. In experiment 1, broilers fed the coarse corn or whole sorghum diets had increased (P < 0.0001) relative gizzard weights compared with broilers fed the fine corn diet. Also, diets containing DDGS yielded increased relative gizzard weights (P < 0.05) compared with diets containing no DDGS. In experiment 2, there was a decrease (P < 0.03) in cecal Escherichia coli when the combination of the coarse ground corn, prebiotic, and DDGS was fed in comparison with broilers receiving no prebiotic or DDGS. These results indicate that diets containing coarsely ground corn or whole sorghum in combination with DDGS can be fed to broilers with no long-term adverse effects on growth performance and nutrient digestibility and that these ingredients can have beneficial effects on AMEn, gizzard size, and cecal microflora in some instances.
