The Effect of Red and White LED Light on Performance, Egg Quality and Some Behavior Characteristics of Laying Hens Raised in Enriched Cages




The objective of this study was to determine the effect of red and white LED light on sexual maturity, performance, egg quality and some behavior characteristics of laying hens. A total of 432 sixteen-wk-old Brown layer pullets (Lohmann) were randomly allocated to 2 treatment groups, each with 12 replicates. Treatment groups were consisted of 1) Monochromatic red LED lighting and 2) White LED lighting. Birds were housed in enriched cages during the experiment (16-32 wk). It was determined that hens reached sexual maturity 5 days and peak egg production 4 days earlier under monochromatic red light than under white light and produced 2,05% more eggs during the experiment. In the same period, it was seen that there was no significant difference in feed consumption and feed conversion ratio (FCR) between the lighting groups. However, it was seen that the hens had better FCR values in red light at 21, 23-26 and 29 weeks when egg production was high.

Egg weight and egg mass were higher in red light. Light color did not influence the egg quality characteristics, the rates of perch, nestbox use and cracked egg of laying hens. As a result, monochromatic red LED light treatment starting at the end of the growth period enabled the birds to reach sexual maturity earlier and produce more eggs during the laying period.
