An energy system is needed to optimize feed formulation and influence economics and sustainability. This study assessed the sensitivity of productive energy (PE) and classic net energy (CNE) to BW…
…adjustment. Thus, in the short term, pigs consume the same amount of total feed resulting in increased energy intake and gain if dietary energy is increased or reduced energy intake…
…on dietary Arkansas Net Energy (ArkNE), metabolizable (AME, AMEn), and classic net (CNE) energy values. Four experiments (E1 to E4) fed broilers a total of 60 pelleted diets within 1-56…
Arkansas net energy (Ark NE) is a productive energy system based on actual dietary energy utilized for gain and maintenance. A total of 48 diets with varying levels of total…
…also measured. Concentrations of digestible energy, metabolizable energy, and net energy in net energy were calculated by regressing soybean meal energy intake on daily intake of soybean meal. Results indicated…
…recorded, body protein, fat, and energy (net energy for gain, NEg) and processing weights (i.e., breast meat, leg quarters; breast-to-leg ratio, BLR) were determined with dual-energy X-ray absorptiometry. Heat production…

…met), but including BC allows detecting +18% FHP differences. FHP and body energy retention (ER), expressed per unit of feed intake, account for productive energy (Arkansas Net Energy; Ark NE)….
…for feeding phases. Two studies were conducted to determine the daily dietary energy utilization for protein deposition by using dual energy x-ray absorptiometry (DEXA) (GE Lunar Prodigy). In Exp1, a…
Productive energy (PE) predicts performance and economics better than N-corrected apparent metabolizable (AMEn) or classic net energy (CNE; CNE = AME – heat increment, HI). This study developed models to…
