The aim of this study was to predict carcass traits in live feedlot yearling swamp buffaloes using real-time ultrasound. Nineteen yearling swamp buffaloes were divided into 2 groups by sex. The mean values of carcass traits including, intramuscular fat (IMF), ribeye area (REA), fat depth at 12th-13rd rib (RIBFT), rump fat depth (RMPFT) and gluteus medius muscle depth at rump (RMPDEPTH) were 3.15%, 7.37 inch2, 0.28 inch, 0.25 inch and 3.82 inch, respectively in female and 2.82 %, 7.75 inch2, 0.37 inch, 0.27 inch and 3.73 inch, respectively in males. The mean of carcass traits were not significant difference (p>0.05) among sex groups. Predicted IMF, REA, RIBFT, RMPFT and RMPDEPTH in female and male feedlot yearling swamp buffaloes were found to be 2.75 %, 7.44 inch2, 0.33 inch, 0.28 inch and 3.77 inch, accordingly. In addition, standard error of estimate of predicted IMF, REA, RIBFT, RMPFT and RMPDEPTH were 0.394 %, 1.242 inch2, 0.087 inch,, 0.054 inch, and 0.091inch, accordingly. In conclusion, real -time ultrasound measurement could be used to predict carcass traits in live feedlot yearling swamp buffaloes. Therefore, ultrasound informations are useful to sort yearling heifers or young bulls for breeding selection or finishing management.
