Plant materials can be ensiled to improve the nutritive value as well as to preserve the materials during storage. Rice straw is a fibrous plant material and as such, its utilisation as animal feed is limited. However, ensiling might improve its nutritive value. In this study, rice straw was ensiled with Lactobacilli as starter inoculum to enhance the fermentation activity. Rice straw with moisture content adjusted to 70% was inoculated with different lactic acid bacteria (LAB) at 10⁶ cfu g-¹ DM. Ensiling was done in tightly closed 0.5 L Scott bottles for 30 days. Chemical analyses of the ensiled rice straw showed significant (p<0.05) decrease in dry matter, NDF and ADF content and significant (p<0.05) increase in crude protein upon fermentation with LAB. Inoculation of LAB isolates in rice straw silage improved the fermentation characteristic, such as significant (p<0.05) decrease in pH and significant (p<0.05) increase in production of lactic acid and acetic acid. Among the five LAB used, L. plantarum and S. bovis were found to be promising in improving the fermentation process during ensiling.
