The Effect of Feeding High Energy Diets Containing Supplemental Fat on Broiler Weight Gain, Feed Efficiency, and Carcass Composition

Abstract We studied the effect of feeding two levels of energy in starter diets [3135 kcal metabolizable energy (ME)/kg low energy and 3410 kcal ME/kg high energy] from 0 to 28 days and finishing diets (3190 kcal ME/kg low energy and 3465 kcal ME/kg high energy) from 28 to 56 days upon broiler weight gain, feed conversion, feed consumption, calorie consumption, and abdominal fat content Feed conversion of male and female broilers fed the high energy starter diet from 0 to 28 days or the high energy finisher diet from 28 to 56 days was superior (P .05) by diet; however, weight gain during the 28 to 56 day feeding period demonstrated a sex-diet interaction (P .05). A sex-diet interaction was observed (P
