“…According to our results, exposing the incubating eggs to 5000-6000 lux white LED increased post-hatch seminiferous tubule diameter and the number of Sertoli cells at 42 days of age as compared to that of chicks hatched from eggs incubated in the dark. Even though we used different intensities of light, our results are partly in parallel with the results of Coelho et al (2021). In a study, broiler eggs were incubated under darkness, under 12 h of lightness, and under 24 h of lightness.…”

“…In a study, quail eggs were incubated under white LEDs, green LEDs, red LEDs, and darkness (control). Growth rates, after the hatch, were higher (P<0.05) in birds from eggs incubated under dark and white LED (Coelho et al, 2021). In another study, the positive effect of continuous lightning during incubation on body weight at hatching was reported by Farghly and Mahrose (2012).…”

“…According to another study, conducted on three weeks old sexually immature male Japanese quails, testicular volume and seminiferous tubule diameters were significantly higher in quails exposed to 100 lux white fluorescent light as compared with quails exposed to 30 lux white or blue LEDs (Yadav and Chaturvedi, 2015). According to Coelho et al (2021), no difference in the anatomical and histological characteristics of the testes due to the light treatment during the incubation except for the diameter of the seminiferous tubules, which was greater (P <0.05) in the dark and in the white LED groups. According to Retes et al (2017), semen volume and sperm concentrations were not statistically different due to the light treatment, except for sperm motility, which was higher (P < 0.05) in birds from eggs incubated in different colors of light.…”

The objective of this study was to monitor the effect of exposing hatching quail eggs to high light intensity on testicular function Quail eggs were distributed into four groups; dark application during the 18-day incubation period (C), light application during the 18-day incubation period (L), 5 days of light + 13 days of darkness (5L), and 5 days of darkness + 13 days of light (5K) and incubated. After the hatch, 40 chicks were selected from each group and placed in rearing cages. On day 42 after hatching the quails were weighed and their testes were removed and then embedded in paraffin. The blood glucose level of the 5K group was higher than the blood glucose level of the L group, but there was no statistically important difference (P<0.05) between the L, C, and 5L groups. The diameters of seminiferous tubules were bigger in the 5L group as compared with the L group. The groups treated with light had bigger tubule diameters than the control group. The number of Sertoli cells was significantly lower in the C group. Incubating quail eggs under five days of darkness and thirteen days of light have a favorable effect on post-hatch male fertility potential

“…Eggshell pigments admit penetration or block different wavelengths of the light spectrum [ 27 ]. However, considering the particularities of each species of birds, the effects of light during the incubation period may be different [ 28 ]. Thus, more studies are needed to understand the transmission of light waves in different colors and species of birds.…”

The use of artificial lighting during the incubation phase is a tool that has been studied with the aim of increasing the production rates and hatchability. Using this, this study aims to investigate the effects of the luminous incidence of white and red monochromatic light on the production and metabolism of broiler chicks subjected to low temperatures. A total of 315 eggs of Ross 708 heavy breeders were used. The eggs were distributed randomly, with 35 eggs per tray, totaling 105 eggs per incubator. The treatments were the following: incubation without the use of light; the use of white monochromatic light; and the use of red monochromatic light. The lamps used were of the LED type. The samples were distributed in the factorial completely randomized experimental design with position effect on the tray. Candling, egg weighing, calculating the probability of survival and egg weight loss were performed. Temperatures were recorded using a thermographic camera. At birth, three chicks per tray were euthanized for evaluation: weight with and without yolk residue, gastrointestinal tract biometry, and blood and liver biochemistry. Analyses were performed using the R computational program. It was observed that there was a significant effect of the treatments on the levels of calcium, phosphorus, cholesterol, amylase, glucose, urea and glutamate pyruvate transaminase on the biochemical profile of the blood and on the thermographic temperatures of the eggs; the experiment was kept at low temperatures resulting in thermal stress, with an average temperature of 34.5 °C. Therefore, the use of red and white monochromatic light in the artificial incubation process for brown-colored eggs is not recommended, because in the post-hatching phase, it promoted the metabolism dysregulation on the blood biochemical profile to control the differentiation in the wavelength of traditional incubation.
