Crude Protein Percentage in Typical Layer Ration
A typical layer ration contains what percentage of crude protein?
- 14–16%
- 16–18% — Correct Answer
- 18–20%
- 22–24%
Explanation:
Correct Answer: 16–18%
A typical layer ration contains 16–18% crude protein. This is lower than broiler rations because layers channel nutrients primarily into egg production rather than body weight gain.
Crude Protein for Layers (BIS 2007)
| Feed Phase | CP% (min.) |
|---|---|
| Layer Chick | 20% |
| Layer Grower | 16% |
| Layer Phase I (22–42 weeks) | 18% |
| Layer Phase II (43–62 weeks) | 16% |
| Typical layer ration | 16–18% |
Quick Comparison
- Broiler ration CP: 22–24% (high for muscle growth)
- Layer ration CP: 16–18% (moderate; for egg protein synthesis)
Daily Feed Requirement for a Layer
- A layer requires 110 g of feed per day.
- Total feed for laying period (21–72 weeks): 40 kg.
Why Other Options Are Wrong
- 14–16% → too low; below BIS minimum for layer phase rations.
- 18–20% → this range overlaps with layer chick and broiler finisher, not typical layer ration.
- 22–24% → broiler ration level; too high for layers (excess protein is wasted and costly).
