Which of the following statements is most correct? Question Select one: a. The net energy value of a diet is always lower than metabolizable energy due to body heat increment. b. The total digestible energy and net energy are the same in all animals. c. The maintenance energy requirement is almost the same value of metabolizable energy in all animals. d. Maintenance energy is always reduced by heat and fecal energy loss. e. The gross energy and digestible energy are not the same only because of the loss in heat increment during metabolism.
