Intestinal digestible bypass protein
Definition
The fraction of Intestinal digestible bypass (feed) protein is the fraction of rumen undegradable protein that can be digested by the small intestine.
Intestinal digestible bypass protein is part of the intestinal digestible protein system: Intestinal digestible protein (DVE) = Intestinal digestible bypass protein + MCP – MFP.
Protein digestibility calculation
Intestinal digestible bypass protein is calculated from the protein content, the percentage of resistance, and the digestibility of the rumen undegradable protein. The digestibility of the rumen undegradable protein (%) is determined using the mobile nylon bag technique. The amount of protein recovered in the manure is the non-digestible portion.
