Impacts of various lighting programs on chicken production and behaviour

Abstract Environmental changes have an impact on agriculture, especially the production of poultry. These changes have caused grave concerns that will negatively affect the health and productivity of chickens. We must consider illumination, density, and dietary aspects when determining the optimal environmental conditions for poultry rearing and output. Each of these variables influences the performance and behavior of birds uniquely. A crucial aspect of evaluating animal well-being is that it understands animal behavior. Artificial lighting has been widely investigated in poultry production over the last fifty years to enhance muscle gain and egg production while preserving an effective feed conversion ratio, bird health, and well-being. Yet, researchers and breeders still disagree over the ideal light quality and quantity, density, and feeding levels for poultry farming, particularly for chickens. This evaluation, therefore, covered the most up-to-date practical methods for enhancing illumination, density, and feeding-related aspects of poultry behavior, health, and production.
