AB  - A study was conducted to investigate changes in chemical compositions and <I>in vitro</I> digestibility of Triticale Straw (TS) treated with liquid ammonia and urea. TS chopped approximately 2 cm length. Liquid ammonia and urea were applied to 1000 g DM of chopped TS at rates of 0, 10, 20, 30 and 40 g kg<SUP>-1</SUP> DM. The chemicals were applied as aqueous solutions, which added 1500 g of water/1000 g of TS DM, thoroughly mixed, stored in plastic containers and kept for 45 days at ambient temperature (22-25°C). Chemical compositions and <I>in vitro</I> digestibility of test materials were determined. The amounts of Crude Protein (CP) and N-NH<SUB>3</SUB> increased (p<0.05) when, liquid ammonia and urea were applied at higher levels (40 g kg<SUP>-1</SUP> DM) but decreased Neutral Detergent Fiber (NDF), however, effect of urea was higher than liquid ammonia. Acid Detergent Fiber (ADF) content decreased (p<0.05) significantly only in Urea-treated TS (UTS). UTS had higher <I>in vitro</I> Digestibility of DM (IVDMD), Organic Matter (IVOMD) and OM in DM (IVDOMD) than Liquid ammonia-treated TS (LTS). As a point of digestibility, the rate of 10 in UTS treatments is equivalent to the rate of 30 in LTS treatments. Liquid ammonia and urea can improve characteristics chemical compositions and <I>in vitro</I> digestibility of TS but, urea was better than liquid ammonia.
