Productive energy, as determined by Arkansas net energy, predicts broiler processing weights, carcass market value, and gross profit.

ABSTRACT: This study assessed the sensitivity of Productive Energy (PE) to breast meat production, feed efficiency, and broiler economics, developed models for processing traits and economics, and examined economics dynamics. The experimental design involved 96 pens, 12 per block and eight blocks, with each pen within block receiving one of 12 dietary treatments for one week. Treatment diets, varying in amino acid concentrations, starch, and energy densities, were control-fed. The weights of processing body parts and net energy for gain (NEg) were determined with Dual-Energy X-Ray Absorptiometry, and fed heat production, fasting heat production (FHP), and net energy for maintenance (NEm) with calorimetry chambers. N-corrected apparent metabolizable energy (AMEn) was determined. PE was calculated as
