Where are volatile fatty acids absorbed most extensively in a healthy adult ruminant?
Correct answer: C. Across the rumen wall
- A. Across the ileal wall
- B. Across the abomasal wall
- C. Across the rumen wall
- D. Across the colonic wall
Explanation
The rumen epithelium absorbs most volatile fatty acids, including acetate, propionate, and butyrate, produced by microbial fermentation. The abomasum mainly performs acid and enzymatic digestion, while the ileum and colon are not the principal sites for this absorption.
