1Chemical analysis of complete diets was analyzed by Ward Laboratories, Inc. (Kearney, NE).
2Dietary electrolyte balance was determined by analyzing complete diets for Na, K, and Cl. Analyzed values were then used with the following equation to calculate dEB: [(Na × 434.98) + (K × 255.74) − (Cl × 282.06)].
