Nearly 100 tons of cattle and buffaloe manure have been treated for 20 livestock households by 3 probiotic types as follows: EMUNIV (7 households), EMIC (6 households) and EMZEO (7 households). The manure treatment using these probiotics had a good effect which the concentration of NH3 and H2S gas was significantly reduced in 1m3 of the air at the stable area (the former decreased by 3-4 times, while the latter reduced by almost half in comparison with those before applying fecal treatment), therefore, the manure lost its odor
markedly decreased the number of helminth eggs (approximately decreased about 9-10 times), the number of E. coli, Salmonella bacteria contained in 1 manure gram was noticeably decreased (about 4-5 times). Thereby, the manure treatment using probiotics reduce the living environmental pollution of human and livestock.
