2.6.1 Energy represented by A is the energy absorbed by the animal after digestion, which is the gross energy minus the faecal energy. Digestible energy 2.6.2 Label B represents the energy lost through urine. Urinary energy 2.6.3 Energy represented by E is net energy, which is used for maintenance and production. Since the animal is pregnant, a function would be for the growth of the fetus. Fetal growth / Production / Maintenance 2.6.4 Step 1: Calculate the digestible energy (A). Digestible energy (A) = Gross energy − Faecal energy; Digestible energy (A) = 37.2~MJ − 9.8~MJ = 27.4~MJ Step 2: Calculate the metabolizable energy (C). Metabolizable energy (C) = Digestible energy (A) − (Gases and urinary energy (B)); Metabolizable energy (C) = 27.4~MJ − 4~MJ = 23.4~MJ 23.4~MJ
