This work was conducted to study the quantitativecarcass traits of 36 buffaloes (12 Murrah - MUR, 12 Jafarabadi - JAF and 12Mediterranean - MED) averaging 18 months old and initial body weight (BW) of330 kg finished in feedlot. Twelve animals of each genetic group were randomlyassigned to three sub-groups (four animals) and distributed to the followingtreatments: Maturity 1 - slaughter weight at 400 kg of BW, Maturity 2 - slaughterweight at 450 kg of BW, or Maturity 3 - slaughter weight at 500 kg of BW. Animalshad free access to a diet containing 50% of forage (DM basis). After each slaughterempty body weight (EBW) was determined through the sum of body parts. No differencesamong genetic groups and maturity were observed for yields of hind and forequarters,whole shoulder and whole rump. However, animals slaughtered at 400 kg of BWhad lower yield of beef plate than those slaughtered at 500 kg of BW while animalson treatment 2 were intermediate. Opposed behavior was observed regarding wholeshoulder yield. Production of meat from Murrah, Jafarabadi and Mediterraneandid not differ for yields of carcass yield and prime cuts.
