Depending on the sex of the animals, males presented better responses in CC (3.68 / 5 points), LW (69.41 kg), CP (56.24 kg) and CR (80.75%), while females obtained 3.38 / 5 points of CC, 65.68 kg of BW, 52.60 kg BW and 79.97% of CR. Regarding the breed, the mestizo animals prevailed over the criollos ones, presenting better CC (3.57 / 5 points compared to 2.71), LW (67.71 kg), CP (54.68 kg) and a CR (80.55% compared to 76.95%).
