Physical, chemical, and energy characteristics of swine urine and feces were determined. Changes in urinary and fecal characteristics were determined as pigs were exposed to changes in ambient temperature, feed intake, and dietary fat concentration as well as increases in body mass. The data indicate a large variation in the characteristics of urine and feces when pigs are exposed to different environmental conditions. Fecal total solids and total volatile solids concentrations decreased as pig mass increased. Urinary total solids and total volatile solids concentrations decreased and urinary energy content increased as ambient temperature increased. Urinary NH3-N concentration was less in the fat-added diet than in the non-fat diet.
