The aim of this study was to determine the effects of lighting type [light-emitting diode (LED) and compact fluorescent (FLO) light] and cage tier on welfare traits such as feather score, body and comb wounds, bumble foot and footpad dermatitis, beak damage, keel bone deformity, finger damage, aggressive pecking behavior, and the avoidance distance test (ADT) in laying hens reared in an enriched cage system. A total of 400 layers were used to determine these traits at 25 and 45 weeks of age. A total of 80 layers were used to determine tonic immobility (TI) duration and induction number. The …

Turkish Journal of Veterinary & Animal Sciences
This study?s aim was to investigate the effects of age, light source type (light-emitting diode (LED), and compact fluorescent (FLO)), and cage tier on production performance and egg quality traits of layers reared in the enriched cage system. A total of 800 Nick Chick White layers were used in the study. A total of 800 eggs were used for egg quality traits at 25 and 45 weeks of age. The enriched cage tiers were coded as I, II, III, and IV from bottom to top. Layer age significantly affected egg mass, hen-day egg production rate, hen-house egg production rate, feed …
