Abstract
2% (mixed) + concentrate (separated, semi-complete diet). The animals were put on a 24-h fast with water ad libitum and they were weighed before taking them to the slaughterhouse. Later, they were slaughtered by the method of captive bolt stunning. The hot carcasses were weighed 4 h after the end of the dissection and remained at temperature of 4 ?C for 24 h to determine the cold carcass weight. Later, the dissection of the left carcass was conducted to determine the percentage of edible meat (first and second class), bone, and excessive
fat. No differences were found for the indicators hot carcass weight, cold carcass weight, yield, first and second-class meat, bone, and fat. Supplying the concentrate twice a day permitted obtaining larger amount of total meat in the carcass.
Key words: cattle, carcasses, sugarcane.
