Improving the Nutritive Values of Rice Straw and Rice Hulls by Ammonia Treatment

Impact of 15N-labeled rice straw and rice straw compost application on N mineralization and N uptake by rice

Incorporation of plant residues in soil affects N and C content and dynamics. This studydetermined the effects of short-term alternative rice (Oryza sativa L.) residue management on Nmineralization and uptake by rice. Pot and laboratory incubation experiments were established byincorporating 15N-labeled rice straw and rice straw compost in paddy soil. The 15N recovered by riceaveraged 16.6%; mo...

The effect of ammonia treatment on the digestibility of rice straw under various process conditions

Sankat, C.K. and Lauckner, B. 1991. The effect of ammonia treat ment on the digestibility of rice straw under various process conditions. Can.Agric. Eng.33:309-313.Rice straw was treatedwith aqueous NH3 at 2,4, 6 and8% of strawdry matter(DM)such that the final measured moisture content was 21% (wet basis) and samples at each level of ammoniation wereheldunderambient (30°C) conditions for 7, 14,...

Nutritive Value of Rice

Microbial fermentation of rice straw: nutritive composition and in vitro digestibility of the fermentation products.

Rice straw was fermented with Cellulomonas sp. and Alcaligenes faecalis. Microbial cells and undigested residue, as well as chemically treated (NaOH or NH4OH) and untreated straws, were analyzed for nutrient composition and in vitro digestibility. In a typical fermentation, 75% of the rice straw substrate was digested, and 18.6% of the total substrate weight that disappeared was recovered as mi...
