Crude Protein Percentage in Typical Broiler Ration
A typical broiler ration contains what percentage of crude protein?
- 18–20%
- 16–18%
- 12–16%
- 22–24% — Correct Answer
Explanation:
Correct Answer: 22–24%
A typical broiler ration contains 22–24% crude protein. Broilers have high protein needs for rapid muscle development and fast body weight gain (market weight at 6 weeks).
Crude Protein Requirements Across Broiler Phases (BIS 2007)
| Feed Type | CP% (min.) |
|---|---|
| Broiler Pre-starter (week 1) | 23% |
| Broiler Starter (weeks 2–3) | 22% |
| Broiler Finisher (weeks 4–6) | 20% |
| Typical broiler ration (overall) | 22–24% |
Why Broilers Need More Protein Than Layers
- Broilers grow from ~40 g (day-old chick) to ~2 kg in just 6 weeks — rapid muscular development demands high protein.
- Layers need less body protein; energy goes into egg production instead.
- Broiler FCR = 2 (2 kg feed needed per kg weight gain).
Why Other Options Are Wrong
- 18–20% → insufficient for maximum broiler growth performance.
- 16–18% → this is the crude protein range for layer rations.
- 12–16% → too low; used for layer grower or certain maintenance rations.
