This study was conducted to determine the volume of pig slurry productinn and the characteristics from 4 swine farms. For the composition of pig slurry produced, contents of N, $P_2O_5$ and $K_2O$, were 0.13, 0.25 and 0.13% in slurry, respectively. Water pollutant concentration in slurry of swine farms, $BOD_5$, $COD_MN$, SS, T-N and T-P, was $24,047mg/{\ell}$, $30,232mg/{\ell}$, $36,833mg/{\ell}$, $2,805mg/{\ell}$, $465mg/{\ell}$, respectively. The average volume of pig slurry was 6.30 ${\ell}/head/day$ and 6.32 ${\ell}$ in spring, 6.69 ${\ell}$ in summer, 6.09 ${\ell}$ in autumn, and 6.12 ${\ell}$ in winter. The average moisture content of slurry was 95.8%. The composition of slurry produced by pig farms.

In this experiment porous calcium silicate (PCS) powder prepared by using a 50 mesh sieve was spread on top of chick droppings to investigate the odor from the manure. Zeolite was used as a comparative purpose. Reduction in ammonia production from chick droppings shortly after the PCS and zeolite application was evident (P<0.05), but there were no difference among treatments afterwards. hydrogen sulfide level was significantly lowered by both PCS and zeolite treatment(P<0.05).

This study was carried out to investigate the quantity of Holstein dry cow manure excreted and their characteristics. The results obtained in this study were summarized as follow; The average body weight of the Holstein dry cow during experiment was 619.9kg. The feed intake(DM basis) and water consumption was 10.7, 38.6kg/day/head, repectively. The manure production of Holstein dry cow was 44.8kg/day/head (feces 26.9, urine 17.9kg). The moisture content of feces and urine was 84.5%, 95.3%, respectively. Wastewater pollutant concentration of $BOD_5$(Biochemical Oxygen demand), $COD_{Mn}$ (Chemical Oxygen demand), SS(Suspended Solids), T-N(Total Nitrogen) and T-P(Total Phosphorus), excreted from Holstein dry cow was 16,874,55,763, 87,333, 2,353, $368mg/{\ell}$ in feces and 5,621, 8,673, 518, 2,423, $3mg/{\ell}$ in urine, repectively. The fertilizer content of manure, N(Nitrogen), $P_2O_5$(Phosphoric acid) and $K_2O$(Potassium oxide) was 0.24, 0.08, 0.15% in feces and 0.24, 0.001, 0.30% in urine, respectively.
