This study was conducted to investigate the nutritional quality. The Dry matter (DM), Organic matter (OM), Crude protein (CP), Acid detergent fibre (ADF), Neutral detergent fibre (NDF), lignin, Ca and P contents of Pajam, Nijershail, Kablabadam, BR 11, BINA 5 and BRRI 29 varieties of rice straw varied from 92.21 to 93.05%, 81.21 to 86.24%, 3.49 to 5.10%, 41.38 to 46.32%, 72.16 to 77.57%, 4.3 to 6.97%, 0.10 to 0.245% and 0.046 to 0.146%, respectively. The OM content in Nijershail was significantly higher (P<0.01) than Kablabadam, BR 11, BRRI 29, Pajam and BINA 5, respectively. The variety BRRI 29 contained significantly higher (P<0.01) CP content (5.1%) than BINA 5, BR 11, Pajam, Nijershail and Kablabadam, respectively. Significantly (P<0.01) higher NDF content was found in BR 11 (77.57%) followed by Kablabadam, Nijershail, Pajam, BRRI 29 and BINA 5, respectively. Acid deter gut Fibre (ADF) content was significantly (P<0.05) higher in Nijershail (46.32%) than Kablabadam, BR 11, BINA 5, Pajam and BRRI 29, respectively. Significantly (P<0.01) higher lignin content was found in BRRI 29 (6.97%) compared to Kablabadam, BINA 5, Pajam, Nijershail and BR 11, respectively. The Ca content in Pajam and BR 11 was significantly (P<0.01) higher (0.245%) than Nijershail, BRRI 29, Kablabadam and BINA 5, respectively. BRRI 29 contained significantly (P<0.01) higher P content (0.146%) compared to BINA 5, Pajam, Nijershail, Kablabadam and BR 11, respectively. Organic Matter (OM) digestibility, and ME content in BRRI 29 was significantly (P<0.01) higher followed Nijershail, BINA 5, Pajam, Kablabadam and BR 11, respectively. Straw of BRRI 29 is expected to provide more nutrients, digestible organic nutrients and metabolizable energy to ruminants.
