This experiment was conducted to know physical characteristics of Brahman Cross heifer’s beef at different type of concentrate. Nine heads of Brahman Cross heifers (1.5-2 year of age) with initial weight of 330±26.93 kg and the final weight of 357±26.82 kg were used. They were devided into three groups subjected to three dietary treatment. P1 treatment concentrate with 11% of crude protein (CP) and 70.42% of Total Digestible Nutrient (TDN), P2 treatment concentrate with 13.03% of CP and 70% of TDN, and then P3 treatment concentrate with 16% of CP and 65% of TDN. The observation of fattening was done for 60 days (2 month). The data were analyzed by analysis variance based on general linear model procedure and Tukey test. The measurement of meat quality was included : value of pH, shearforce, cooking loss, water holding capacity, meat colour and marbling score. The value of pH P1 5,82±0,05 has a significantly higher result than P2 and P3 with 5,62±0,02; 5,60±0,03, the shearforce of P2 8,79±0,07 which was significantly higher than P1 and P3 which were 7,26±0,10; 7,33±0,26, the cooking loss were significantly different in each treatment of P1, P2, and P3, they are 37,23±0,09; 40,21±0,78; 44,04±0,66 respectively, the water holding capacity of P1 25,54±0,93 were significantly lower than P2 and P3, there are 30,67±0,23;31,50±1,24 respectively, while marbling measurement and meat colour were analyzed by using descriptive test with each of average value 1,33±0,5 and 5,33±0,5. Physical characteristics of Brahman Cross heifer’s beef in the range of normal meat.
