Digetible crude protein

DIGESTIBLE CRUDE PROTEIN

  • As determining the DCP of large number of foods is impracticable, often the crude protein value of the feed and the digestible coefficient of crude protein is referred from the tables available in the literature.
  • This holds good for concentrates which has relatively constant composition and digestibility coefficient.
  • With roughage, a different approach is usually taken owing to their greater variability and relatively greater importance of metabolic faecal nitrogen in material of low protein content.
  • In this case regression equation for DCP and CP are used to calculate the former. A typical equation

DCP ( g/kg DM) = CP(g/kg DM) X 0.9115 – 36.7

  • Is widely used for grasses, hays and silages.
