The Effects of Green LED Lighting During Incubation on Embryo Growth, Hatching Performance, Post-Hatch Growth Performance, Intestinal Morphology, Slaughter and Carcass Characteristics.
Article in Veterinary medicine and science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIn recent years, research has increasingly focused on the role of light exposure in stimulating embryonic development of broilers, particularly regarding how different lighting conditions during incubation may affect growth and performance outcomes.
objectivesThis research examined the effects of continuous green LED lighting (560 nm, 15 lux) throughout incubation on embryo growth, hatching performance, post-hatch growth, intestinal morphology, and carcass traits.
methodsIn this study, 600 Ross-308 hatching eggs were divided into two groups: a control group incubated in darkness and a group exposed to continuous green LED light (560 nm, 15 lux) throughout incubation.
resultsResults showed no significant differences in embryo weight, length, or yolk sac usage between groups at day 19 (p > 0.05). Green LED lighting reduced relative heart weight (p < 0.01) and chick weight at hatch (p < 0.05) while significantly shortening incubation time (p < 0.001). Embryonic mortality and hatchability were not affected (p > 0.05). By day 42, broilers incubated under green LED light exhibited lower body weight and cumulative weight gain (p < 0.05), though feed conversion ratios remained similar across groups (p > 0.05). Carcass analysis revealed no significant differences in yield, but relative liver weight was higher in the green LED group (p < 0.01). Subtle changes in intestinal morphology, particularly in the jejunum, were observed with age.
conclusionWhile green LED lighting did not affect hatching performance, it negatively impacted body weight, heart weight, and liver development.
