Effect of Artificial and Natural Day Light Intensities on some Behavioral Activities, Plumage Conditions, Productive and Physiological Changes for Japanese Quail

Abstract

This study was designed to evaluate the effects of different artificial light intensity; 10, 50, 250, 500 lux and natural day light (NDL, average 375 lux) from 3-18 week of age on behavioral activities, plumage conditions, productive and physiological traits for grower and layer of Japanese quail. A total of 270 Japanese quails chicks (3 week old) were randomly assigned to five treatment groups according to different light intensities. The results showed that the birds subjected at NDL and 250 lux spent significantly more time standing than those recorded in 50 and 500 lux groups. Also, birds kept at 500 lux spent significantly more time walking compared with other groups. The lowest plumage deterioration was detected in birds kept under NDL compared with other experimental groups. The heavier body weight (p#0.05) at 6 weeks and weight gain from 3-6 weeks were detected for birds reared at NDL and 250 lux compared with 500 lux and did not significant with the rest of the experimental groups. While, Hen Day Egg Production (HDEP) and Total Egg Mass (TEM) were linearly increased beginning of 50 lux with increasing light intensity. Fertility percentage was significantly higher in 250 lux group than in 50 lux and was not significant with the other groups. Hatchability percentage was significantly decreased in 10 lux group compared with the other groups. Serum level of T 3 was decreased linearly with increasing light intensity. Birds kept at 500 lux had reduced overall number of Ovarian Yellow Follicle (OYF), relative weight of ovaries and testes and cloacal gland area compared with the other groups. From our results, it could be concluded that neither high light intensity (500 lux) nor low light intensity (10 lux) had a positive effect on most traits. Therefore, to maximize productive, reproductive parameters and increase revenue economic may be by using moderate artificial light intensity if we used closed-side housing system or NDL if we used open side housing system for production of Japanese quail.

Impact of different artificial light intensities on some reproductive, productive performance aspects and blood picture of male quail

“…Other research indicates that artificial light has beneficial economic effects on quail results. The current study revealed that reaction to different light intensities did not influence the level of triiodothyronine hormone level relative to the control group, this result disagrees with pervious study (37) who found that light induces increased releasing of metabolic hormones, including triiodothyronine, thyroxine, insulin, growth hormone and insulin like growth factor-1.…”

“…The mean values of broiler behaviors were affected by different light intensities. These findings are in agreement with the results of Khalil et al (2016) who observed thatdim light reduced eating and drinking behaviour. But, it is contrary to the findings of Newberry et al (1988) who claimed that the light intensity had no effect on the behaviour of eating and drinking.…”
