 Abstract
The current study investigated the fate of organic matter in piggery slurry under two different store systems(closed store system and open store system) in association with different temperature. Thirty days after storing in both systems at , it was observed that the content of organic matter remained in piggery slurry with closed store system was twice more than that with open store system implying more efficient degradation of organic matter with open store system. Temperature also influenced on the organic matter degradation in piggery slurry as shown decline in TS and VS contents as the temperature increased. With store at , 29% of initial organic matter was reduced while there was only 23% reduction of organic matter at . There was no difference in the type of organic fatty acids(VFAs) produced under the range of temperature(20, ) simulating summer condition. Increases in organic fatty acids contents with hydrolysis and acid producing microbial was observed from 15 days after initiating store of the piggery slurry and the total organic acid amount produced 30 days after store was and at and , respectively. These corresponded to 5.4% and 17.4% of the initial organic matter contents in piggery slurry, respectively.
