Live weight and feed intake of birds were measured weekly on a pen basis. Feed intake of all feeds was measured separately (i.e., for Choice, feed intake of corn, protein concentrate, and grit was measured separately). Feed intake calculations were adjusted for mortality. The Formulated diet was sampled and analyzed for nutrients. To sample Choice, diet make-up was calculated for the first wk (28 to 34 d) and the last wk of the growing period (56 to 64 d), based on the feed ingredients selected by the birds. The percentage of ingredients for the small sample diets was based entirely on the recorded percent consumption by the birds and compounded solely for the purpose of nutrient analysis.
