Dietary treatment did not affect the concentration of odorous compounds in urine (P ≥ 0.07).
Total VFA concentration in feces decreased as WDGS increased in the diet (P < 0.01), but branched-chained VFA concentrations (isobutyrate and isovalerate) and phenol in feces increased when WDGS replaced corn in the diet (P ≤ 0.04).
