when the bird were changed to grower diets, six different treatments were included (table 6). there was no significant effect of feeding diets with 15% from 1 to 35 d or from 14 to 35 d on body weight, feed intake, feed conversion, or mortality, compared to feeding the control diet with on DDGS. Birds fed diets with 30% DDGS either from 1 to 35 d on 14 to 35 d after previously receiving diets with 0 or 15% DDGS had significant reduced body weigh and increased feed conversion as compared to birds fed the control diet with on DDGS. Birds that were fed 30% DDGS after previously being fed diets with 15% DDGS in the starter period appeared to perform somewhat better than those that had been previously fed the diet with 0% DDGS. but still had significantly reduced performance. Birds that had been fed 30% DDSG from 1 d of age had numerically higher mortality that did those fed other diets, but due to the inherent high variability in mortality this was not statistically significant.
