Defining Characteristics of Roughages
Which of the following is true about roughage feed stuff:
- These are bulky & low-density feed
- Poor in digestibility
- Low in energy content (or) TDN
- All the above — Correct Answer
Explanation:
Correct Answer: All the above
All three statements about roughage are true: roughage feeds are bulky and low-density, have poor digestibility, and have low energy content (TDN <60%).
Roughage — Defining Characteristics
| Feature | Roughage | Concentrate (comparison) |
|---|---|---|
| Bulk/density | Bulky, low density | Compact, high density |
| Digestibility | Poor/low | High |
| TDN/Energy | <60% TDN | >60% TDN |
| Crude Fibre | >18% | <18% |
| Main function | Belly-filling (rumen fill) | Energy supply |
Examples of Roughage
- Dry: Straw, stover, hay
- Succulent: Silage, green fodder, pasture, tree leaves
Why Other Options Are Wrong
- Bulky & low-density alone → correct but incomplete
- Poor digestibility alone → correct but incomplete
- Low TDN/energy alone → correct but incomplete; all three features together define roughage
