Evaluation of an in vitro digestibility procedure for dietary fiber in high-fiber feed ingredients fed to growing pigs

The objective was to develop and validate a nutritional tool to measure in vitro digestibility of fiber among high-fiber ingredients. Also to measure changes in gut physiology and function of growing pigs fed diets with different fiber types and concentrations.

Key Points:

  • Dietary fiber digestibility affects the concentration of metabolizable energy among sources of corn distillers dried grains with solubles (DDGS).
  • In vitro procedures can be used to measure digestibility and fermentability of fiber among corn DDGS sources.
