Abstract: The objective of this study was to determine the slaughter traits of 5 pure Dehong buffalo (D), 5 Dehong×Ni-li buffalo(ND) and 5 Dehong×Murrah buffalo(MD) at an average age of 35.8 months on pasture system. There was significant difference (P < 0.05) on live weight, carcass weight, dressing-out percentage, net meat weight, the percentage of net meat weight in live weight, the percentage of meat production and the bone-meat ratio of D and ND, and ND higher than those of D. This experiment showed that the effect of crossbreeding of Dehong×Ni-li buffalo was more distinctness than Dehong×Murrah buffalo, and the slaughter traits of pure Dehong buffalo has improved through crossbreeding.
