Arkansas Net Energy: A productive energy system sensitive to broiler performance and body composition.

ABSTRACT: This study determined the sensitivity of productive energy (PE; Arkansas Net Energy) to performance and body composition and developed predictive models based on PE. Chicks (2,148 day-old ones) were placed in 96 pens and assigned to one of 12 dietary treatments, including varying concentrations of total digestible amino acids (TDAA), digestible CP (dCP), digestible fat (dFat), digestible starch, and non-starch polysaccharides (NSP). Eight replications per treatment, one per block, were used, being the block consecutive groups of birds weekly starting the seven-day experimental period. In each block, birds were control fed to meet similar ME intake, placed in calorimetry chambers to determine fed (HP) and fasting heat production (FHP), and scanned (Dual-Energy X-Ray Absorptiometry) to deter
