Ask a question in the formula (digestible energy)

The "digestible energy" of corn shown in the picture is 3.40. How is this calculated with "metabolic energy"? The recipes on my books are all marked (corn: metabolic energy (megajoule, kg): 14.6), but I don't understand 3.40 here? And the standard "digestible energy" in this formula is 3.5. I think many recipes are marked with "metabolic energy". What's the difference between the two? Attachments: you need to log in to download or view attachments. No account number? Registration-according to international units, energy should be expressed in joules. 1 joule = 4.184 calories, then 1 kcal = 4.184 kilojoules. You can figure it out by yourself-it is recommended that the landlord take a look at the basic books on animal nutrition. I don't understand. Is his 3.40 unit of corn (megajoules, kilograms) or something? Gz002dp in 2009-12-6 23:24 add the following content landlord can you give an example? I'm here. Thank you! Corn: 14.6 megajoules divided by 4.184 = 3.489 mega calories or 3.5 mega calories
