This study was carried out to evaluate the effect of rice straw processing by Lactobacillus, Multi
enzymes and calcium hydroxide on the digestibility and nutritional value by gas production and chemical
methods. Processed for 60 days in anaerobic conditions in the 3 kg tanks were repeated by three times in spray
method. The experiment was done in completely randomized design and data were analyzed with SAS and
Neway software. After processing the samples dried and Chemical compounds Crude Protein (CP), Neutral
Detergent Fiber (NDF), Acid Detergent Fiber (ADF), Ether Extract (EE), Ash, Crude Fiber (CF), NFC (Non
Fiber Carbohydrate), Nitrogen Free Extract (NFE) and Organic Material (OM) and degradation were
determined at the times of 0, 2, 4, 6, 8, 12, 24, 48, 72 and 96 hours in gas production method and parameters
such as (OMD-SCFA-ME-NEL-CP-DMD) were determined. Each of three processing operation, reduce the
amount of cellulose and hemicelluloses in the straw and bacterial processing (%51/2), allocated the least
amounts of ADF while enzyme production (%53/8), chemical (%57/9) and control straw (%58/2) maximum
allocated the most amounts of ADF. The same trend also has been in the NDF and bacterial processing has the
lowest and enzymatic, chemical and control straw have the greatest amount of NDF, respectively. The amount
of gas production rate in the bacterial methods was more than the other method and with increasing incubation
time, shows upward trend.
Key words: Bacterial, chemical, digestibility, enzymatic, gas production, nutritional value, rice straw
