“…Guo et al . [41] agreed with our findings; they found an improvement of a-Naphthyl-acetate esterase and increased antibody production in broilers exposed to intermediate or low-intensity blue lights for the increased melatonin or activation of T and B lymphocyte proliferation.…”

Background and Aim: Manipulating lighting colors and regimens is considered an effective mean for improving broiler productivity. The influence of red, blue, and white light-emitting diode (LED) was investigated using three different regimens of lighting and darkness; continuous 23 h light (L):1 h dark (D), continuous 18 h L:6 h D, and intermittent 16 h L:8 h D hours on the performance, carcass weight (CW), feed and water intake (WI), serum glucose (GLUCO), triglycerides (TG), and cholesterol (TC), intestinal bacterial load, growth and metabolic hormones, and efficiency of Newcastle disease (ND) vaccine. Materials and Methods: A total of 252 1-day-old Ross broilers on deep litter were divided into nine groups. The 1st, 4th, and 7th groups were exposed to continuous 23L:1D, the 2nd, 5th, and 8th groups were exposed to continuous 18L:6D, and the 3rd, 6th, and 9th groups were exposed to intermittent 16L:8D (4L:2D, 4 times) lighting regimen using red, blue, and white LED lights, respectively. A total of 1350 samples (225 sera, 225 swabs, and 900 organ samples) were collected. Results: Blue LED group revealed a highly significant increase (p<0.01) in live body weight, body weight gain, performance index, CW, spleen, heart, and liver weights, and anti-ND antibody titer, as well as a highly significant decline (p<0.01) of feed intake, WI, GLUCO, TG, TC, growth hormone, insulin, tri-iodothyronine (T3), tetra-iodothyronine (T4), total bacterial count (TBC), and total Enterobacteriaceae count compared to red and white LED lights in all tested lighting regimens. Continuous 23L:1D and 18L:6D regimens were significantly (p<0.01) superior to intermittent 16L:8D in their influence on the performance, CW, biochemistry, hormonal profile, and bacterial load. Conclusion: The blue LED light associated with continuous 18L:6D or 23L:1D h regimen is highly recommended in broiler houses for their enhancing the productive performance, growth, and immunity.

“…These results proved that broiler chickens were more sensitive to light intensity. Whereas, when boilers reared at low light intensity environment, they had a low level of stress and strong light is considered a stress factor in poultry production (Guo et al, 2018). Increased percentage of NDV antibody titer under dim blue light in this experiment suggested that low light intensity improved the cellular and humoral immune responses of broilers.…”

Poultry producers accustomed to use light colours in broiler production as atrial to increase their productivity, especially in the developing countries to cover the animal protein gap. This experiment was planned to study the effect of different blue light colour intensities (high, medium and dim) on a recently imported Indian River (IR) broilers to Egypt. In this study, 270 one-day old Indian River broiler chicks were used. The birds were exposed to high blue light intensity (HBLI), medium blue light intensity (MBLI) and dim blue light intensity (DBLI), through a monochromatic lighting system that was installed in different rooms for 24 hours daily. The birds were randomly divided and housed into three well controlled pens of 5.46 m2 with three replicates of 30 each using a density of 17 birds/m2 in the room. The results showed that the broilers reared under DBLI had a significantly (p< 0.05) higher body weight, body weight gain, Newcastle disease virus antibody titer and foot pad dermatitis with obviously, economic Feed conversion ratio (FCR) and low activities and heterophyil/lymphocyte ratio in comparing with (MBLI) and (HBLI). In conclusion, poultry producer can use dim blue light in their farms to reduce the activities and increase the productivity of the birds.

“…In the control group, the light intensity was 18 lux whereas in the experimental group, the light intensity was measured between 0 and 12 lux, below this value, in a large part of the house. Guo et al (2018) express that broilers under low light intensity might have similar performances. The findings of the study are consistent with this view.…”

The experiment was carried out to evaluate effects of point Light Emitting Diode (LED) lights source attached to the feeders and drinkers on the broiler performance compared with the standard ceiling with the bulb in environment controlled house with two clusters. Total of 3360 chicks were divided into 2 groups (control and experimental) consisting 3 replicates of 560 chicks with 12.5 birds/m 2 stocking density. Although, light intensity was measured as 18 lux at the level of feeders for the control group, it was measured 82 lux inside the feeders, 12 lux at the outer edge of them, while the measuring was showing 1 lux at 15 cm distance from the feeders 8 lux at the water dropper and zero in other areas for the experimental group. Standard rearing techniques and commercial diets were used during experimental period and parameters such as growth performance, feed conversion ratio (FCR) and mortality of broiler chicks were determined. The mean chick weight at the beginning of the experiment was similar in the control and experimental groups. There was no difference between lighting applications at the age of first week, however, at later stages, body weight (BW) was recorded significantly higher (P≤0.05, P≤0.01) in LED illumination treated group compared to control group. No significant differences were observed in feed intake and FCR between lighting treatments. In 42 day old, feed conversion ratios in control and LED lighting treated group were determined as 1.651 and 1.607, respectively (P>0.05). The mortality rates of control and LED lighting treated groups were found to be 5.24 and 3.51 (P≤0.05) at the age of 42 days. No negative effect of Point LED lights system on weekly body weight gain, feed intake, and feed conversion ratios were observed, but a positive effect on cumulative body weight and mortality. Therefore, pointed LED can be used as a lighting system in broiler production being cost effective without compromising the productive performance.
