“…Lighting is one of the essential environmental factors in confined poultry houses. Light not only provides illumination for the poultry but also influences their physiological responses, behavior, growth and development, and production performance ( Lewis and Morris, 1998 ; Olanrewaju et al., 2006 ; Parvin et al., 2014 ; Borille et al., 2015 ). Currently, owing to the high energy efficiency, long working life, availability in different peak wavelengths, low electricity consumption, and low rearing cost ( Hassan et al., 2013 , 2014 ; Huber-Eicher et al., 2013 ; Sultana et al., 2013a , b ; Liu et al., 2017 ), light-emitting diodes ( LED ) are gradually becoming a substitute for conventional incandescent and fluorescent lights for lighting in poultry houses ( Yang et al., 2016 ; Li et al., 2018 ).…”

“…The quantity (intensity) and quality (color) of light are 2 important factors affecting poultry productivity ( Manser, 1996 ; Prayitno et al., 1997 ; Parvin et al., 2014 ; Elkomy et al., 2019 ). Some researchers have indicated that high light intensity could increase poultry activity, feather pecking and cannibalism, and sexual development ( Prayitno et al., 1997 ; Renema and Robinson, 2001 ; Shi et al., 2019 ) and increasing light intensity can reduce leg disease and total egg production of poultry ( Newberry et al., 1988 ; Lewis and Morris, 1999 ).…”

The behavior, growth and development, and production performance of poultry are affected by the light environment. The influence of light results from a combination of light sources, light intensity, light color, and the photoperiod regimen. With light-emitting diode ( LED ) lamps applied in poultry housing systems, specific light colors are desired for each time period for layer chickens. The objective of this study was to investigate the effects of a 2-phase mixed color lighting program (phase 1: blue-green, 1 D–13 wk; phase 2: yellow-orange, 14–20 wk) using LED lights on the blood parameters, skeletal development parameters, and sexual development parameters of caged layer chickens during their brooding and rearing periods. Fifty-two chickens were raised from 1 D to 20 wk of age in each of the 4 treatment groups with 3 replicates, with white (400–700 nm) light at phase 1 and phase 2 ( WL treatment as the control); blue–green (435–565 nm) light at phase 1 followed by yellow–orange (565–630 nm) light at phase 2 ( BG-YOL treatment); yellow–orange LED (565–630 nm) light at phase 1 and phase 2 ( YOL treatment); and blue–green (435–565 nm) light at phase 1 and phase 2 ( BGL treatment). The results showed that the serum Ig concentrations of the layer chickens in the BG-YOL treatment and BGL treatment were higher than those in the WL treatment at 13 wk of age ( P < 0.05). At the age of 20 wk, the serum glucose concentration levels of the pullets after the WL and BGL treatments were lower than those after the YOL treatment ( P < 0.05). Compared with the WL treatment, the YOL treatment significantly increased the bone mineral density of the layer chickens ( P < 0.05), and BG-YOL treatment promoted the development of the sexual organs (oviducts and ovaries) of the laying hens at the age of 20 wk ( P < 0.05). For the 50% egg production age, the YOL treatment was earlier than the other 3 treatments. This study demonstrated that appropriately staged spectral control using LED lights could have positive effects on the immune performance, bone development, and production performance of caged layer chickens during their brooding and rearing periods.

“…Light is an essential part of the physical environment and a powerful exogenous factor, which affects physiological development, behavioural processes and welfare of domestic fowls (Onbasilar et al, 2007; Parvin et al, 2014). Thus, artificial light has been widely used to modulate avian reproduction and growth rate.…”

Monochromatic green light-emitting diodes (LED) light stimuli influences the posthatch growth performance of chicks. This study was undertaken with the following objectives: i) to examine whether the green LED light stimuli induces an overheating effect by determining weight loss rate of fertile eggs during incubation period; ii) to look for the development of eyes and other primary organs at different ages of embryos and newly hatched chicks. Arbor Acres fertile broiler eggs (n = 480) were randomly assigned to 3 incubation groups and exposed to continuous white light, green light, or a dark environment (control) from the first day to 19 d of incubation. The light sourced from LED lamps with the intensity of 30 lx at eggshell level. The results showed that either green or white light stimuli during incubation did not significantly affect the weight loss rate of fertile eggs, hatching time, hatchability, chick embryo, or body weight (BW), the weight percentage of heart, liver, and eyes, as well as obvious systematic abnormalities in eye weight, side-to-side, back-to-front, or corneal diameter from 15 d of embryogenesis to 6 d of posthatch (p>0.05). Compared with the dark condition, green light stimuli during incubation tended to increase feed intake (p = 0.080), improved the BW gain of chicks during 0 to 6 day posthatch (p<0.05), and increased the percentage of pectoral muscle to the BW on 3- and 6-day-old chicks. In addition, embryos or chicks in green light had lower weight percentage of yolk retention on 19 d of embryogenesis and 1 d of posthatch in comparison to those in dark or white group (p<0.05). These results suggest that providing 30 lx green LED light stimuli during incubation has no detrimental effect on the development of eyes, heart and liver of embryos and hatchlings, but does have potential benefits in terms of enhancement of the chick growth during the early posthatch stages. In addition, the fertile broiler eggs stimulated with 30 lx green LED light during incubation does not cause an overheating effect.

“…Jusqu'à présent, seule la durée d'éclairement a pu être étudiée en période hivernale chez l'oie (Bonnefont et al, 2015). Plusieurs autres facteurs, comme la nature du spectre lumineux et son intensité pourraient cependant avoir un impact significatif sur le comportement d'ingestion, les performances pondérales et le bien-être des palmipèdes, comme c'est le cas chez les poulets de chair (Mendes et al, 2013 ;Parvin et al, 2014). Concernant la température, des études en conditions climatiques contrôlées permettraient d'évaluer précisément son effet sur l'hyperphagie et la stéatose, et ainsi de définir des itinéraires techniques optimaux.…”

La production de foie gras, telle que pratiquée aujourd’hui, est remise en question par les associations de protection animale, mais aussi par le Conseil de l’Europe. Le Comité Permanent de la Convention Européenne pour la protection des animaux dans les élevages a ainsi recommandé que des études portant sur des méthodes alternatives à la prise forcée d’aliment chez les palmipèdes soient mises en place dans les pays européens producteurs de foie gras. Cette synthèse a pour objectif de présenter l’état d’avancement des recherches sur ces méthodes alternatives. Les voies de synthèse et de stockage de lipides chez les oiseaux seront abordées ainsi que le comportement alimentaire et le métabolisme hépatique des oiseaux migrateurs, ayant permis de définir les bases biologiques des recherches menées sur la stéatose spontanée chez les palmipèdes domestiques. Les résultats des recherches conduites sur l’engraissement hépatique spontané des palmipèdes, les effecteurs de celui-ci et l’impact en terme de durabilité du système seront discutés. Enfin, plusieurs perspectives de recherche sur des leviers possibles tels que l’alimentation, la conduite d’élevage, la sélection génétique et l’étude du microbiote intestinal, seront proposées.
