Talk:Atwater system

Is this formula really correct?
$${\text{Metabolisable Energy}} = \left(\text{Gross Energy in Food}\right) - \left(\text{Energy lost in Foods, Secretions and Gases}\right)\text{Urine}.$$ I understand that the term "Energy lost..." is multiplied by "Urine". Is that correct? I'm not a nutritionist, so I don't know enough about this system. --SnowRaptor (talk) 14:54, 30 May 2009 (UTC)
