Application of the 1996 NRC to Protein and Energy Nutrition of Range Cattle

  title={Application of the 1996 NRC to Protein and Energy Nutrition of Range Cattle},
  author={H. H. Trey Patterson and Don C. Adams and Terry J. Klopfenstein and Gregory P Lardy},
Based on applications of the 1996 National Research Council (NRC) Nutrient Requirement of Beef Cattle (2000 update) model at our laboratories and on use of the model to evaluate published literature, it is our assessment that the NRC model (Level 1) represents an advancement in nutrient requirements of grazing cattle. We evaluated 8 published studies (35 treatment observations) to compare observed changes in body condition score (BCS) to those predicted by the NRC model, and to develop criteria… CONTINUE READING
