This work was aimed at evaluating the biochemical meat traits from Mediterranean buffaloes finished in feelot and slaughtered at different weights. Twenty eight Mediterranean young buffaloes, averaging 240kg initial live weight and nine months of age, were used. The animals were full fed with total mixed ration in feedlot until reaching slaughter weights of 450, 480, 510 and 540kg live weight (treatments). The pH values and temperature of the Longissimus dorsi and Biceps femoris muscles were collected at 2 hours intervals during 24 hours after the slaughter. Meat color was determined through the subjective and objective methods. No interaction effect was observed between treatment and time of ph and temperature collection. No treatment effects was observed in relation to the pH and temperature in the two studied muscles (Longissimus dorsi and Biceps femoris) during the cooling carcass process. The average values of initial pH and ultimatel pH of Longissimus dorsi and Biceps femoris muscles were 6.6 and 5.4; 6.3 and 5.5, respectively. The average values of initial and ultimate temperature of Longissimus dorsi and Biceps femoris muscles, were 39.7°C and 4.1°C; 40.4°C and 7.0°C, respectively. Meat color by the subjective method, did not differ among treatments studied, with general average of 3.41 points. Meat color obtained by the objective method, did not differ among the treatments studied, with average values: L * = 35.16; a*=12.43 and b*=5.29. In spite of presenting darker than bovine meat, buffalo meat doesn't bring damages as for the visual aspect for the consumer.
