Light Requirement for Layers
Light requirement for a layer is:
- 10 hours
- 16 hours — Correct Answer
- 18 hours
- 20 hours
Explanation:
Correct Answer: 16 hours
Layers require 16 hours of light per day for optimum egg production. The remaining 8 hours are in darkness.
Light Requirements Across Poultry Types
- Layer: 16 hours of light/day
- Broiler: 23 hours of light/day (near-continuous light to maximize feed intake and growth)
Why Light Matters for Layers
- Light stimulates the hypothalamic-pituitary-gonadal axis, triggering LH and FSH release which drives ovulation and egg production.
- Light should never be decreased during the laying period, as this signals the approaching winter and suppresses production.
- Recommended light intensity for layers: 10 lux at bird level.
- Red light is used to control cannibalism and feather pecking in poultry.
