A trial involving nineteen zebu steers with initial live weight of 270 kg were conducted with the objective of determining their energy requirements and the efficiency of utilization of the metabolizable energy for gain (kg) and maintenance (km). Four steers were slaughtered at the beginning of the trial, performing the reference group, three were fed at maintenance level and the remaining were uniformly allotted to a complete randomized design, in three treatments, with different levels of concentrate in the diets […]
