Influence of Lighting Regimes on Egg Production and Quality in Layer Chickens

CHAPTER ONE

1.1 Background to the Study

Light is one of the most critical environmental factors affecting poultry behavior, physiology, and productivity. In layer chickens, lighting influences feeding patterns, hormone secretion, and reproductive performance (Abiola et al., 2020). Proper lighting regimes help maintain consistent egg production and improve egg quality parameters such as shell strength and yolk color.

Different lighting schedules, including variations in intensity, color, and duration, can significantly affect laying performance. For example, longer light exposure stimulates reproductive hormones that enhance egg-laying cycles, while poor lighting may cause stress and irregular production (Onyeanusi et al., 2019). Therefore, understanding the influence of lighting regimes on egg performance is vital for improving flock management and optimizing production efficiency.

1.2 Statement of the Problem

Many poultry farmers in Nigeria still rely on natural daylight without considering its variation across seasons. This inconsistency often leads to a decline in egg production and poor egg quality during short daylight periods. There is a need for scientific evaluation of lighting programs suitable for tropical environments.

1.3 Objectives of the Study

1. Examine the effect of different lighting regimes on egg production rate.

2. Assess the influence of lighting duration on egg weight and shell quality.

3. Identify the most effective lighting schedule for optimal egg performance.

1.4 Research Questions

1. How do lighting regimes affect egg production and quality?

2. What duration of light exposure enhances layer performance?

3. Which lighting system produces the most consistent egg quality?

1.5 Significance of the Study

This research will provide evidence-based recommendations for poultry farmers to improve lighting management. By understanding the link between light and egg production, farmers can increase efficiency and reduce economic losses caused by seasonal changes.

1.6 Scope of the Study

The study will be conducted on commercial layer farms where artificial lighting systems can be controlled. Data on egg production, shell quality, and feed consumption will be collected over an eight-week period.

1.7 Operational Definition of Terms

• Lighting Regime: A controlled schedule of light exposure designed to influence animal behavior or physiology.

• Egg Production: The total number of eggs produced by hens within a given period.

• Egg Quality: The internal and external attributes that determine egg freshness and market value.
