Ruminal microbial digestion of protein Flashcards
1
Q
What are the stages in microbial digestion of protein?
A
- Peptide absorbed by bacteria
- Broken down to AA
- AA synthesised to microbial protein
OR
- deaminated to ammonia and VFA which the bacteria use to manufacture endogenous protein
2
Q
What are the products of microbial metabolism of straight chain AA?
A
acetate, propionate, butyrate
3
Q
What are the products of microbial metabolism of branched AA?
A
branch chained VFA, used as growth factors by microbes
4
Q
How are AA and protein digested by the rumen once microbial degradation has occurred?
A
In abomasum in same way as in simlple stomached animals
