Potential of Fermented Rice Straw
The straw consists of polysaccharides, such as cellulose and hemicelluloses. Even though straw contains enough cellulose to make it an excellent source of dietary energy for ruminants, it is a poor-quality feed in its natural state because of low digestibility and protein content, poor palatability, and bulkiness. Various pretreatment processes, including physical, chemical and biological are used to increase the acceptability of straw to animals, thus increasing daily feed intake, and to enhance the rate of digestion and increasing the availability of nutrients.
Biologically treated (with ligninolytic fungi) roughages have higher digestibility for most of the nutrients (both cell walls and cell soluble) with an increase in crude protein content as compared to the untreated material, besides ensuring more fermentable substrates in the rumen. The treatments have increased palatability, daily feed intake, nutritive value and maintained the health quality of ruminants as compared to untreated rice straw.
