Introduction Body energy refers to the amount of internal energy a cow has at her disposal to support physiological functions (milk production, growth, reproduction, maintenance, activity). Ideally, body energy would be directly measured using individual feed intake and physiological function records. In field conditions, however, such information is not available. For this reason, indirect measures of body energy have been suggested based on the body condition score and live weight of a cow.
