Correct answer: B. Mixing it in progressively over several days
- A. Replacing the entire ration at one feeding
- B. Mixing it in progressively over several days

- D. Adding large amounts of grain without roughage
Explanation
Progressive introduction gives rumen microorganisms time to adapt to changes in nutrient supply and fermentation. A sudden ration change, particularly a sudden increase in grain, can cause acidosis and reduced performance.
