Total Feed Requirement During Laying Period
Total feed requirement during laying period (21–72 weeks) is:
- 18 kg
- 25 kg
- 40 kg — Correct Answer
- 50 kg
Explanation:
Correct Answer: 40 kg
During the full laying period from 21 to 72 weeks of age, a layer hen consumes a total of approximately 40 kg of feed.
Calculation Basis
- Duration: 72 − 21 = 51 weeks = 357 days
- Daily consumption: 110 g/day
- Total = 357 × 110 g ≈ 39.27 kg ≈ 40 kg
Layer Ration Requirements (BIS 2007)
| Parameter | Layer Phase I | Layer Phase II |
|---|---|---|
| CP% (min) | 18% | 16% |
| Ca% (min) | 3.0% | 3.5% |
| ME (kcal/kg) | 2600 | 2400 |
| Salt% (max) | 0.5% | 0.5% |
High calcium (3–3.5%) is essential in layer diets for proper egg shell formation (shell = ~94% calcium carbonate).
