The objective of this work was to establish a model to estimate the metabolizable energy (ME) requirements for laying hens from Lohmann LSL line, by the factorial method. To determine the influence of ambient temperature on ME requirements for the maintenance, experiments were accomplished in environmental controlled rooms at constant temperatures of 12, 22 and 31 ºC, by the comparative slaughtering technique. The net energy for weight gain was determined by regression of carcass energy content in function of body […]
