Which change generally increases the energy density of a livestock ration when it replaces an equal amount of cereal carbohydrate?
Correct answer: C. Adding vegetable oil
- A. Adding limestone powder
- B. Adding wheat straw
- C. Adding vegetable oil
- D. Adding common salt
Explanation
Vegetable oil contains much more energy per unit weight than carbohydrate, so it increases ration energy density. Straw, limestone, and salt contribute little usable energy compared with oil.
