STUDY ON PROBIOTIC EFFECTS IN TREATING BUFFALO AND CATTLE MANURE IN TUYEN QUANG PROVINCE
Abstract
Investigating the current status of the buffaloes and cattle manure treatment in 4 districts (including Chiem Hoa, Ham Yen, Yen Son and Son Duong district) of Tuyen Quang province, the results showed that: 64% of livestock households did not apply manure treatment accumulating in a long time, scattered around the stable ground causing environmental pollution. 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.
