Resumo: 	The Brazil sacrifices many dairy calves at birth, which can become a very serious problem merchandising. The objective of this experiment was to evaluate the physical carcass composition and meat quality characteristics of Holstein calves in feedlot or pasture with supplementation, slaughtered at 140, 180, 220 or 260 kg body weight. In the early termination calves had on average 57 kg and 58 days of age. The confined animals were fed forage (corn) and concentrated, in the ratio of 40:60 and concentrated pasture supplemented with 1% body weight. The experimental design was completely randomized in a factorial 2 x 4 (two feeding systems x four slaughter weights). It was observed a significant interaction between slaughter weight and finishing system only for the texture of the meat. The finished animals on pasture showed improved texture with increased weight, whereas the confined animals did not affect the weight. Animals finished on pasture had higher muscle percentage (69.48% vs 66.57%), and lower fat percentage (9.58% and 9.75 kg vs 13.20% and 13.08 kg) compared to confined animals. There was a linear increase in the total amount of muscle, bone and fat, muscle / bone ratio, compared edible portion / bone, palatability and juiciness when increased slaughter weight. The percentage of bone and meat coloring decreased linearly with the increase of slaughter weight. The proportion of muscle and fat, showed quadratic behavior. The animals of dairy breeds are excellent producers of lean meat, with good smoothness, flavor and juiciness.
