A dairy cow receives a diet rich in rapidly fermentable starch and develops a sharp fall in rumen pH. Which condition is most likely?
Correct answer: D. Ruminal acidosis
- A. Grass tetany
- B. Simple indigestion
- C. Ketosis
- D. Ruminal acidosis
Explanation
Rapid starch fermentation produces acids faster than the rumen can neutralize them, causing ruminal acidosis. Ketosis is mainly associated with negative energy balance after calving, not primarily with low rumen pH.
