Diego Martínez (University of Arkansas)     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 gain (BWG), feed conversion ratio (FCR), and net energy for gain (NEg) and maintenance (NEm), and developed models to predict BWG, FCR, a ...

IntroductionThe poultry industry aims to optimize the breast weight of the broilers because of its relatively higher market value. Through the years, improvements in breast meat yield have not only led to myopathies (Caldas-Cueva et al., 2021) but also to increased heat production (Martinez et al., 2019) due to the higher body protein content and turnover rates (Maharjan et al., 2020a; 2021b) in m ...

IntroductionOptimizing the breast size of broilers is a critical economic target due to its higher market value versus other cut-up pieces. Historical improvements in breast production have shown an impact on the efficiency of broilers in using dietary energy (Martinez et al., 2019a), which accounts for 70–75 % of the poultry feed cost. They have also been associated with quality conditions ...

1. IntroductionModern broilers show increasing growth rates, improved feed conversions, and increased breast meat size and yield, which play a pivotal role in the economics and sustainability of poultry production. Indeed, across the years, broilers have become leaner [1], and the industry aims to increase breast meat production due to its higher market price.To achieve this aim, operation profess ...

IntroductionIn poultry, the net energy (NE) is the sum of the energy retained in the body and lost through heat production. Under its classic definition, the prediction of NE requires precise and accurate determinations of fasting heat production (FHP) and heat increment, which accounts for the energy production due to feeding, digestion, and the associated physical activity (Maharjan et al., 2021 ...

IntroductionThe poultry industry aims to increase the breast weight of broilers due to its higher market price. However, the breast size is associated with meat conditions such as woody breast (Maharjan et al., 2021a), the body protein turnover (Maharjan et al., 2020a, Maharjan et al., 2021b) and lean mass weight (Martinez et al., 2020a), and changes in the partitioning of the dietary energy (Mart ...
