Thirty-six Landrace pigs (75 days, 25 kg) were initially used to investigate the effect of dietary protein levels on $NH_3$ emission, fecal odor and microbes of growing finishing pigs in enclosed confinement. The growing and finishing pigs were offered three dietary protein levels; 14.27%, 15.54%, 17.49% and 9.73%, 10.63%, 11.69%, respectively in a $3\times3$ factorial arrangement. In growing pigs, there was no interaction between protein and diet in all fecal composition indicating that the combined effects of dietary protein levels and weight was not sufficient to influence changes in fecal chemical composition. However, fecal $NH_4-N$ was significantly affected by the weight groups (p<0.05). In finishing pigs, fecal N was positively correlated to protein changes in the diet(r=0.568, p < 0.05) while fecal NDF and ADF was reduced by 27 and 45%, respectively. Dietary protein manipulation from 11.69% to 9,73% was effective in reducing fecal N by 9.48% during the 56-day feeding trial.
