Cellular immune response of infectious bursal disease and Newcastle disease vaccinations in broilers exposed to monochromatic lights

Abstract

To investigate the effects of various monochromatic lights on T lymphocytes proliferation and serum nitric oxide production in chicken vaccinated with infectious bursal disease and newcastle disease vaccines, a total of 60 one-day-old broilers were exposed to red, green, blue, white and yellow light by using a light-emitting diode system for 6 weeks. The results indicated that the proliferation of peripheral blood T lymphocytes in the chickens exposed to white and green lights significantly increased when compared with other groups at 37 days of age (P < 0.05). In the early days, the results were different. The enhancement of T lymphocytes proliferation with green and yellow lights occurred at 18 days, whereas the enhancement with green light was less than other lights at 30 days. Red light promoted NO (nitrix oxide) production at maximum level in the chickens, while green light suppressed it at minimum level after 37 days. These results suggested that green and white lights had strong effects on immunity, especially at the last days of rearing.

Effect of different lighting sources on the performance of broiler breeder hens

“…These results reflect that the Arbor Acres Plus breeder hens were more comfortable (less stressed) and calmer (less aggressive behavior) under LED lighting compared to birds raised under Inc lighting during the rearing period. Lewis and Morris (2006), Mendes et al (2010), Sadrzadeh et al (2011), Firouzi et al (2014, Zhang et al (2014), Mousa-Balabel et al (2017), Abdel-Azeem and Borham (2018), Soliman and El-Sabrout (2020), Wu et al (2022) and Horodincu and Solcan (2023) reported that light source and color (wavelengths) can affect birds' behavioral activities, health, immunity, and mortality. Similarly, Kamanli et al (2015) revealed that LED lights reduced the mortality rate of birds.…”

Light regimen on health and growth of broilers: an update review

“…During the rearing period post-hatch, green light enhanced T lymphocytes proliferation and had promotive effects on immunity ( Avesta et al, 2011 ). Interestingly, replacing white light with blue light have been reported to modify the activities of heat shock biomarkers, and confer higher resistance to heat stress on broilers ( Abdo et al, 2017 ).…”
