Impact of coccidiosis and enteritis on poultry energetics and feed energy value

Diet energy density is a major factor in broiler production costs, but metabolizable energy system has limitations in accurately predicting broiler performance due to its low sensitivity to actual metabolism. The productive energy (i.e., Arkansas Net Energy) system, which measures productive energy, provides a more accurate assessment of energy utilization, particularly under conditions affected by gut health, like enteritis and coccidiosis. This article highlights opportunities for assessing the effects of enteritis and coccidiosis on poultry energetics, evaluating dietary interventions on gut health, improving precision nutrition, and supporting One Health strategies in antibiotic-free production systems.
