Lighting Programs: Explained
Lighting programs are key in poultry management, controlling light exposure to influence growth, maturity, and egg production. This module explains their importance and application throughout the breeder cycle to optimize flock health and productivity.
START
The Science Behind Lighting Programs
Lighting programs are designed to control the amount and duration of light that birds receive at each stage of their life cycle. Light acts as a biological signal, influencing growth, sexual maturity, and egg production. By adjusting light exposure, producers can delay or stimulate reproductive development, ensuring birds reach the right physiological state before laying begins. This precise control helps maintain flock uniformity, supports health and welfare, and maximizes production efficiency.

The Science Behind Lighting Programs
Breeder houses typically use LED or fluorescent lighting because these provide consistent brightness and can be dimmed for gradual changes. Longer light periods encourage egg production, while shorter light periods during the pullet stage delay sexual maturity so birds develop properly before laying.
- Light stimulates activity, feed intake, and reproductive hormones.
- Darkness allows birds to rest and maintain healthy growth.

How is the lighting controlled?
Lighting is managed through automated control systems that adjust both duration and intensity. MTech Systems products integrate lighting programs with environmental controls, allowing producers to schedule gradual light changes, simulate dawn and dusk, and maintain precise photoperiods. This automation ensures consistency, reduces stress on birds, and supports optimal growth and egg production.

Finish
Brood/Pullet Stage (0-21 Weeks)
Purpose: Focus on skeletal development, body weight control, and preparing for reproduction. Males and females are often housed separately. Birds are transferred to lay farms around 21–23 weeks.
Click to turn on the lights.
Next
Lay Farm Stage (20-21 Weeks)
Purpose: Birds are moved from pullet to lay farm, unless using all-in/all-out. The goal is for hens to reach maturity and start mating, ensuring consistent egg production and natural mating in breeders.
Click to turn on the lights.
Next
Point of Lay/Capitalization (Approx. 25 Weeks)
Purpose: This stage marks peak production readiness as birds reach sexual maturity and produce high-quality eggs. “Capitalization” is when previous costs are included in the asset value and depreciated over the laying cycle, marking a key economic and biological milestone with the flock generating returns.
Click to turn on the lights.
Next
Lay Period (Approx. 25 Weeks)
Purpose: Longest and most productive phase of the breeder cycle. The goal is to maintain consistent egg production while preserving flock health and fertility. During this time, lighting programs, nutrition, and male management work together to sustain peak performance. Proper management ensures high-quality hatching eggs, good shell integrity, and optimal hatchability throughout the cycle.

Lay Period
Lighting remains at 14–16 hours of continuous light daily to keep the reproductive system active and prevent birds from going out of lay. Consistency is critical—any sudden changes in light duration or intensity can disrupt hormone regulation and reduce egg production. By maintaining a stable lighting schedule, producers support uniform laying patterns, fertility, and overall flock productivity.
LIGHTING PROGRAMS
Lay Farm Stage
Lighting is gradually increased to 14–16 hours per day to stimulate the hypothalamus and pituitary gland, which trigger the release of reproductive hormones. This increase signals the birds’ biological clock that it’s time to start laying. Proper timing of this light increase ensures birds are physically mature before egg production begins, supporting peak performance and flock uniformity.
LIGHTING PROGRAMS
Point of Lay/Capitalization
Lighting and capitalization go hand in hand because light is the key trigger for sustained egg production. At this stage, the lighting program maintains 14–16 hours of continuous light daily, reinforcing the hormonal signals that keep the reproductive system active. Consistent light exposure ensures hens remain in lay and achieve peak production quickly and uniformly. Any disruption in lighting can negatively impact egg output and flock performance, making precise light management essential for profitability.
LIGHTING PROGRAMS
Brood/Pullet Stage
Lighting starts at 23–24 hours per day to boost feed intake, activity, and early skeletal growth. Over time, it’s reduced to 8–10 hours daily to delay sexual maturity. Light exposure affects multiple glands that control reproductive hormones. By limiting light, producers prevent birds from maturing too early, ensuring the reproductive system develops fully for strong performance later.
