Monochromatic light-emitting diode (LED) source in layers hens during the second production cycle
ABSTRACTLight is an important environmental factor for birds, allowing not only their vision, but also influencing their physiological responses, such as behavioral and reproductive activity. The objective of this experiment was to evaluate the impact of different colors of monochromatic light (LED)...

The objective of this experiment was to evaluate the impact of different colors of monochromatic light (LED) sources in laying hens production during the second laying cycle. The study was conducted in an experimental laying house during 70 days. A total of 300 laying hens Isa Brown® genetic strain, aged 95 weeks, in the second laying cycle were used in the study. The artificial light sources used were blue, yellow, green, red and white. The light regimen was continuous illumination of 17 h per day (12 h natural and 5 h artificial) in a daily light regimen of 17L:5D (light: dark). The Latin Square design was adopted with five treatments (five colors) divided into five periods, and five boxes, with six replicates of ten birds in each box.

The monochromatic light source may be considered as an alternative to artificial lighting in laying hens during the second production cycle.http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1415-43662015000900877&lng=en&tlng=enluz artificialprodução de ovoscor de fonte luminosa |
