Odors were produced in the reactor where contained the swine excreta sampled from the pigery and were analyzed the major odor materials based on the odor contribution index. The container hoggery where six pens were separated was set up in S-myun, Gyeonggi-do, Korea: one was control group, the other were experimental group. Sixty weaners were raised and their excreta were sampled every week to the test of the effect of feed type probiotics. Some probiotics showed very effective deodorizing activity during the whole experimental periods. All products had positive effects on the reducing odor intensities after 4 to 5 week periods. The odor contribution analysis represented the main odor compounds were trimethylamine and volatile sulfur compounds such as hydrogen sulfide, mercaptane, and dimethyl sulfide.
