“…These findings are important, because they confirm that the positive effect of in ovo GL photostimulation during the hatching process (from the time the eggs are transferred to hatching trays and until hatch), will remain during the entire growth period, and will give results similar to GL photostimulation during the entire incubation period. Furthermore, it is possible that the in ovo GL photostimulation effect on plasma GH levels during the last critical stage of incubation (as shown in Dishon et al., 2021 ), may affect the hormonal imprinting process, by affecting the responsiveness and quantity of the GH receptors, as found during last stages of incubation and hatching ( Dishon et al., 2021 ) as well as during the post-hatch period in this experiment. According to Csaba (1986) , hormonal imprinting processes occur when a hormone affects its receptors either in quantity, responsiveness, or both.…”

“…It was shown in several studies, including our previous papers, that in ovo GL photostimulation elevate the expression and secretion of different components of the somatotropic axis ( Halevy et al., 1998 ; Zhang et al., 2014a , 2014b ; Dishon et al., 2017 ; Dishon et al., 2018 ). In our previous paper ( Dishon et al., 2021 ), we discovered that in ovo GL photostimulation of broiler embryos from embryonic day ( ED ) 18 until hatching (hatching period), showed similar elevation in somatotropic axis activity, manifested by increased plasma GH levels and hypothalamic GHRH and liver GHR and IGF-1 mRNA levels on the day of hatching. The aim of this study was to examine the effect of selected in ovo GL photostimulation periods on post-hatch broiler growth and somatotropic axis activity.…”

Targeted in ovo green light ( GL ) photostimulation during the last days of broiler egg incubation increases embryonic expression of the somatotropic axis, similar to in ovo green light photostimulation from embryonic day ( ED ) 0 to the end of incubation. The aim of this study was to examine the effect of selected in ovo GL photostimulation periods on post-hatch broiler growth. Four hundred twenty fertile broiler eggs were divided into 7 treatment groups: the first incubated in the dark (standard conditions) as a negative control; the second incubated under monochromatic GL from ED0-ED20 (positive control); the third group incubated under monochromatic GL light from ED15-ED20; the fourth, fifth and sixth groups were incubated under monochromatic GL on ED16, ED17, and ED18, respectively; and the seventh group was incubated under monochromatic GL from ED18-ED20. All illumination was provided intermittently using LED lamps. After hatch, all chicks were transferred to a controlled room under standard rearing conditions. The group incubated under green light from ED18 until hatch showed similar results to the positive control group in body weights, as well as breast muscle weights (as % of body weights), and an elevation in the somatotropic axis activity during the experiment. We suggest that broiler embryos can be exposed to in ovo GL photostimulation from ED18 until hatch (hatching period), and still exhibit the same performance as obtained by photostimulation from d 0 of incubation.

“…A stimulatory effect of monochromatic light on body weight has been observed after embryonic exposure to green light (Rozenboim et al 2004(Rozenboim et al , 2013Zhang et al 2014b), although some studies did not find this stimulatory effect (Dishon et al 2018;Tong et al 2018). Studies exploring mechanisms mediating possible stimulatory effects of green light have suggested changes in the activity of the somatotropic axis (Halevy et al 2006;Dishon et al 2021). In our experiment, concentrations of thyroid hormones did not differ between groups.…”

“…Moreover, recently, melatonin has been suggested to be involved in developmental programming (Chen et al 2013;Hsu and Tain 2020). Interestingly, a recent study indicates that the critical period for the green light to influence the somatotropic axis occurs in the final stages of embryonic development, after day 18 (Dishon et al 2021), when the melatonin biosynthesis steeply increases.…”

Light during incubation can influence embryonic and postembryonic development of chickens, but the underlying mechanisms are poorly understood. Previous studies have demonstrated that red and blue lights during incubation had opposite effects on the development of embryonic melatonin biosynthesis; red light results in the highest and blue light in the lowest amplitude of the daily rhythm. Therefore, in this study, we investigated if exposure to monochromatic red (632 nm) and blue (463 nm) light during incubation can differently influence growth, selected biochemical (glucose, cholesterol, triacylglycerols) and endocrine (corticosterone and thyroid hormones) traits and behavioural parameters during postembryonic development in broiler chickens. For analysis, we used 10 and 11 hatchlings incubated in red and blue light, respectively and 10 birds per each group (six males and four females) in 3-weeks-old broilers. During the rapid growth phase (days 18, 20 and 21 of age), higher body weight was recorded in broilers incubated under red compared to blue light, whereas endocrine and metabolic traits did not differ between the treatments. The improved growth rate was related to behavioural traits, mainly because chickens incubated in red light exhibited more passive (resting, standing, preening, dust bathing) and less active behaviours (walking, foraging, fighting, wing-flapping) than the blue-light incubated birds. The time spent for eating and drinking and the results of the tonic immobility test did not differ between both groups. Our results suggest that red and blue monochromatic light during incubation can differently program the postembryonic development of broilers, with possible consequences for their growth and welfare.

“…By giving monochromatic light, birds were found to prefer green and blue light during certain growth periods ( Khosravinia, 2007 ; Cao et al, 2008 ). Stimulation with monochromatic green light increased somatotropic axis activity ( Dishon et al, 2021 a) and plasma prolactin levels during embryonic phase ( Dishon et al, 2017 ), especially after 15 d of hatching ( Dishon et al, 2018 ). Also, green light stimulation during embryogenesis improved the post-hatch body weight, breast muscle growth and feed conversion ratio of broilers ( Zhang et al, 2012 , 2016 ).…”

The importance of lighting regimen is increasing with the industrialization of poultry production, as lighting has been intimately associated with not only the establishment of rhythm and synchronous physiology of broiler chickens, but also the secretion of hormones associated with broiler maturation and growth. In recent years, increasing attention has been paid to the effects of lighting management on growth performance, immune status, and welfare of broilers. An appropriate lighting regimen, including proper source of lighting, intensity, duration, and wavelength (color) of light, is crucial to improve the growth performance and welfare of broilers. In this review, we updated the impacts of different light regimens on health and growth performance of broilers.
