Objective and methods of conducting digestion trials in ruminants

OBJECTIVES AND METHODS  OF CONDUCTING  DIGESTION TRIALS IN RUMINANTS

Objective

  • The digestibility of dry matter and nutrients in feedstuff is determined by conducting digestion trial.
  • The digestibility of nutrient is used for calculation of the
    • Digestibility of Crude Protein (DCP) 
    • Total Digestible Nutrients (TDN)  in feedstuff, which is calculated by adding the amount of digestible crude protein, digestible carbohydrate (crude fibre and nitrogen free  extract) and (2.25 x digestible ether extract)

Methods

  • In vivo Methods
    • Direct Method
    • Indirect
      • By difference
      • By using indicator/marker
  • Semi in vivo (In sacco) method
  • In vitro method
