Proper lighting can enhance feed efficiency, leading to better weight gain, and also stimulate hormone production, boosting egg production in layers

Light management, including light intensity, duration, and even color, significantly impacts poultry growth, productivity, and overall health. Optimal light conditions encourage activity, improve feed conversion, and stimulate hormone production, leading to good quality as well as number of eggs.

Proper lighting stimulates feeding behavior, leading to improved growth rates and better feed conversion. Broilers exposed to optimal lighting conditions feed more consistently, grow faster, and reach market weight more efficiently, resulting in higher productivity and reduced time to marketProper lighting stimulates feeding behavior, leading to improved growth rates and better feed conversion.

Light management significantly impacts poultry growth and productivity. Adequate light exposure stimulates activity, promoting better feed conversion and weight gain. It also influences hormone release, impacting reproductive performance and egg production. Furthermore, proper lighting helps establish rhythmicity, synchronize essential functions like body temperature, and enhance feeding and digestion.
Elaboration:
Growth and Development:
Poultry, especially broilers, benefit from specific lighting regimens. For example, 20 hours of light per day has been shown to promote the highest growth rate in young broilers. As birds age, they can adapt to shorter day lengths. However, extremely short or long day lengths can negatively impact growth.
Reproduction:
Light, especially during the laying period, plays a crucial role in egg production. Birds need a minimum of 16 hours of light per day for optimal egg production. Light stimulates the release of hormones like FSH and LH, which are essential for ovulation and egg shell formation.
Behavioral Benefits:
Proper lighting helps ensure the birds’ well-being. It allows for adequate flock inspection, facilitates access to feed and water, minimizes injurious behavior (like feather pecking), and supports normal eye development.
Nutrient Metabolism:
Light influences the bird’s metabolism, including how they process nutrients. This can impact feed efficiency and overall health.
Hormonal Influence:
Light stimulates the release of hormones like growth hormone-releasing hormone, which can impact growth, maturation, and reproduction.
Disease Prevention:
Sunlight, when incorporated into the lighting scheme, has natural disinfectant properties, reducing the spread of diseases.
Energy Efficiency:
Natural light can reduce the need for artificial lighting, leading to lower energy costs and a more sustainable farming practice.

Growth Rate
1. Broilers (eat birds): Light duration and intensity impact feed intake and activity.
Shorter dark periods (18 – 23 hours of light/day) encourage continuous feeding, leading to faster growth.
However, too much light can cause leg problems and stress, a short dark period (e.g., 1–4 hours) helps with bone development and rest.
2. Reproductive performance (layers and breeders):
On set of lay: Light stimulates the hypothalamus, triggering reproductive hormone production. Increasing day length (photoperiod) mimics springtime and induces egg production.
Peak production: 14–16 hours of light per day is ideal for layers to maintain peak egg production.
Breeder flocks: Proper light management synchronizes sexual maturity, improving fertility and hatchability.
3. Behavior and welfare:
Light affects bird activity levels, aggression, and comfort.<div>
Low-intensity light: (5–10 lux) can reduce aggression and cannibalism in layers.
Intermittent lighting: patterns can reduce energy costs and improve feed conversion in broilers.
Providing natural dawn and dusk simulations reduces stress by preventing sudden darkness.
4. Light spectrum (color):
Birds perceive light differently from humans.</div><div>
Red/orange light (long wavelengths): Stimulates reproduction (used in laying houses).
Blue/green light (short wavelengths): Calming effect, promotes growth and reduces activity in broilers.
UV light: Enhances vision, feather pecking reduction, and natural behaviors.
