The objective of this work was to study the effect of dietary ME levels on the performance and the energy metabolism of male broilers on growing phase, from 22 to 43 days old. Two hundred and eighty-eight broilers were ramdomly assigned to three energy levels (3,050; 3,200 and 3,350 kcal/kg) and three feeding levels (ad libitum, 75% and 50% ad libitum), with four replicates of eight birds, to determine the energy maintenance requirements and the energy efficiency utilization. The method […]
