Wrinkle: How Do DDGS & Enzymes Affect Hen Rations?
Researchers from Egypt fed laying hens increasing amounts of DDGS with or without an exogenous enzyme. They then measured performance of the hens as well as egg quality. They observed that including DDGS up to 12% of the diet did not affect most performance measures. Similar to previous research, they also observed that increasing DDGS improved the yolk color of the egg. In this case, enzyme addition had little effect on hen performance.
