This work was carried out to investigate the quantity of manure excreta and characteristics in growth and production phase of Holstein dairy cattle. The average manure production of dairy cattle under condition of ad libitum feeding was 41.5kg/head/day(feces 24.9, urine 16.4kg). The average moisture contents of feces and urine were 85.0% and 93.9%, respectively. Water pollutant concentration, BOD5, CODMn and SS excreted from dairy cattle were 15,444mg/ℓ, 53,159mg/ℓ, and 40,528mg/ℓ in feces and 8,454mg/ℓ, 1,116mg/ℓ, and 962mg/ℓ in urine, respectively. And The daily loading amount of BOD5, CODMn, SS in dairy cattle manure were 523g, 1,416g and 1,025g, respectively. N, P and K contents of manure produced by dairy cattle were 0.33, 0.49 and 0.20% in feces, and 1.02, 0.27 and 1.03 in urine, respectively. In the concentrations of mineral and heavy metal of manure, Ca, Na and Mg contents were 1.56, 0.24 and 0.69%, and Zn, Cu, Cr, Pb and As were 69.23, 19.14, 2.89, 7.73 and 2.94 ppm, respectively. In conclusion, Dairy farms can be estimated optimum nutrient and pollutant balance to effectively manage the manure produced.
