How is energy content of feed determined?

The energy content of feed is typically determined through laboratory analyses that measure the digestible energy (DE), metabolizable energy (ME), or net energy (NE) of the feed. These methods often involve bomb calorimetry to assess gross energy, followed by digestibility trials to evaluate how much energy is absorbed and utilized by animals. Additionally, standard equations and tables may be used to estimate energy content based on feed composition. Ultimately, these analyses help in formulating diets that meet the energy needs of animals effectively.
