UDP protein, or undegraded dietary protein, refers to the portion of protein in animal feed that escapes breakdown by microbes in the rumen of ruminant animals.
In simpler terms, UDP protein is the protein that passes through the rumen of animals like cows and sheep without being digested by the microorganisms present there. This undegraded protein then becomes available for digestion and absorption in the small intestine.
Here's a breakdown:
- Ruminants: Animals with a four-compartment stomach, including the rumen (e.g., cattle, sheep, goats).
- Rumen: The first and largest compartment of the ruminant stomach, where microbes break down feed.
- Dietary Protein: Protein consumed through the animal's diet.
- Undegraded: Not broken down.
Therefore, UDP is a crucial protein source for ruminants, providing amino acids directly to the small intestine after bypassing the rumen's microbial digestion.
