This study was performed to analyse the concentration of odorous compounds in the piggeries. Piggeries for different types of pigs include piglets, growing pigs, gestating and lactating sows. Slurry from these piggeries was sampled every month for chemical analysis. Short chain fatty acid (SCFA) was 9,862 ppm (piglet), 8,410 ppm (growing pigs), 6,791 ppm (fattening pigs), 3,508 ppm (lactating sows) and 1,687 ppm (gestating sows). Branched chain fatty acid (BCFA) was 1,634 ppm (piglet), 1,206 ppm (growing pigs), 868 ppm (fattening pigs), 493 ppm (lactating sows) and 185 ppm (gestating sows). Concentration of phenols was 209 ppm (piglet), 166 ppm (growing pigs), 127 ppm (fattening pigs), 85 ppm (lactating sows) and 36 ppm (gestating sows). Indoles was 18 ppm (piglet), 14 ppm (growing pigs), 8 ppm (fattening pigs), 6 ppm (lactating sows) and 4 ppm (gestating sows). Altogether, concentration of odorous compounds was decreased as pigs got aged.

We planned to study how the chemical disposal designed by SOP can affect on physicochemical compositions of the livestock excrement. According to Livestock Manure Management Scheme, we experimented in two steps; the first step, NaOH treatment-Citric acid neutralization, and then the second procedure, Thermophilic Aerobic Oxidation (TAO) system. Physicochemical compositions of the 3-days-old samples after NaOH treatment were pH 10.31, EC 24.54 mS/cm, SCOD 3,022 mg/L, T-N 4,315 mg/L, $NH{_4}^+-N$ 1,960 mg/L, and not detected E. coli.. And those of one-day-old samples after citric acid neutralization were pH 7.36, EC 32.89 mS/cm, $SCOD_{Mn}$ 12,733 mg/L, T-N 4,787 mg/L, $NH{_4}^+-N$ 2,450 mg/L, and E. coli. not detected. In contrast, the physicochemical compositions of the treatment plots after the second treatment with TAO system (72hr) were pH 9.42 EC 24.21 mS/cm, $SCOD_{Mn}$ 3,660 mg/L, T-N 3,616 mg/L, $NH{_4}^+-N$ 1,190 mg/L, and no detection of E. coli.
