Metabolizable Energy Values Determined with Intact and Cecectomized Roosters

intact or cecectomized were used to determine the ME of a diet. Seven intact and 7 cecectomized roosters were fasted for 3 d, with total excreta collection on d 2 and 3. Approximately 1 wk after completion of the trial, the same roosters were force-fed 28 g of a diet that was 85% corn and 15 % soybean meal after a 1-d fast. Excreta were collected from d 2 and 3 and dried. There was no differ-ence in the energy and nitrogen excreted by intact and Key words: apparent metabolizable energy, true metabolizable energy, rooste
