Water-soluble P excretion in feces was similar for cattle fed all 4 diets (P ≥ 0.11). Total N excretion increased linearly as dietary WDGS inclusion increased (P < 0.01) and was due to a linear increase in urinary N excretion (P < 0.01). Total S excretion also increased as WDGS concentration increased in the diet (P < 0.01).
