“…These results suggest that the shorter incubation period of the GL group of eggs is related to the higher growth rates of their embryos. The observation that lighted incubation of chicken eggs reduced hatch time is consistent with other researchers (Siegel et al, 1969;Walter and Voitle, 1972;Coleman and McDaniel, 1975;Bowling et al, 1981) who have reported a reduction in hatch time from 5 h to 3 days due to lighted incubation.…”

“…Similar improvement in hatchability were reported from lighted incubation of meat type strain eggs (Szymkiewick et al, 1985). However, these findings were not in agreement with Zakaria (1989) who reported no difference in hatchability of meat-type breeder eggs between FL and dark incubations, nor do they agree with those of Bowling et al (1981) who reported a reduction in hatchability of White Leghorn eggs due to lighted incubation. The hatch time of the GL and D treatments of 465 and 489 h of incubation, respectively, revealed that the GL incubated eggs hatched earlier by approximately 24 h (Figure 1).…”

“…Further study may be needed to clarify these points. This finding agrees with the results of Gill and Gangwar (1985) and Bowling et al (1981), but contradicts with the findings of Lauber and Shutze (1964) and Lowe and Garwood (1977), Coleman (1979) and Zakaria (1989) who found no differences in body weight at hatch between lighted and dark incubations of eggs. Whilst Coleman and McDaniel (1975) reported an increase in body weight at hatch of FL incubated eggs.…”

The effects of dark-control (D) and continuous green light (GL) exposure of incubated meat-type breeder eggs (Hybro) on embryonic growth from 5 to 15 days of age, hatching time, hatchability per cent and chick hatching weight were investigated in three consecutive experiments at 33, 38, and 41 weeks of age. A total of 798 eggs were used in this study. Eggs were set in an incubator on trays either in the D or under two tubes of 20-watt green fluorescent light during the first 18 days of incubation. Eggs from both treatments were transferred to the dark hatching compartment at 19 days of incubation. The light intensity was in the range of 1,340 to 1,730 lux at the surface of the eggs. GL incubation of eggs significantly (p<0.01) increased weight (expressed as an absolute value) and daily weight gain of embryos at 11 and continued to 15 days of age, hatchability per cent by 4.8%, reduced dead embryos per cent and chick weight at hatch by 37 and 2%, respectively and accelerated hatching time by about 24 h when compared with the D-control incubation. Chicks hatched at 504 h of incubation had significantly (p<0.01) higher body weight, expressed as an absolute value or as a percentage of egg weight, than those hatched earlier at 456 h of incubation. It was concluded that the GL incubation of meat breeder eggs reduced incubation period and chick weight at hatch and increased embryonic growth and hatchability per cent.

“…Archer (2017) found that the Red and White light treatments had a higher hatch of fertile eggs than those of both Green and Dark treatments, but he found that Green light did not improve hatchability in his study suggesting that the wavelength of light responsible for increased hatchability. On the other hand, this result disagreed with Bowling et al (1981) who reported a reduction in hatchability of White Leghorn eggs due to white lighted incubation. Moreover, Zakaria (1989) reported no improvement in hatchability of meattype breeder eggs incubated under white fluorescent light.…”

Key words:Quail, Broiler Breeder, Incubation, Light, HatchabilityLight influences hatchability efficacy of poultry eggs as well as their productive and reproductive performance. Apparently fertile eggs of Japanese quail and Cobb 500 broiler breeder used in this study and incubated surrounded by dark, red and green light environments in order to investigate their effects on hatchability, embryonic mortalities and egg weight loss during incubation. Results revealed that, Red and Green light had significant increase (P < 0.05) on both scientific and commercial hatchability of Japanese quail and Cobb 500 eggs compared to those exposed to darkness during incubation. Moreover, Red light decreased (P < 0.05) early embryonic mortalities. Total egg weight loss of Japanese quail significantly decreased by application of green and red light color during incubation, Meanwhile, Green light decreased the total egg weight loss Cobb 500 broiler breeder eggs. These results suggested that Red or Green light is possibly the key spectrum to improve hatchability.

1. Eggs from two layer-type breeder flocks (ISA-W vs Leghorn) between 30 and 45 weeks of age were used in 4 trials to study the effects of lighted incubation on embryonic growth from 5 to 18 d of age and hatchability per cent (HP). The physical dimensions, eggshell characteristics and conductance (EC) of eggs of the two strains were compared. 2. Eggs were set in an incubator on trays either in the dark-control or under two tubes of 20-watt white fluorescent light during the first 18 d of incubation. The light intensity ranged from 1230 to 1790 lux at the surface of the eggs. Eggs were transferred to dark hatching compartments at d 19 of incubation. 3. The genetic make-up of birds influenced the physical dimensions and eggshell characteristics of eggs. ISA-W eggs had higher weight, surface area (ESA), volume (EV), width, EC, shell volume and HP, and lower ESA:EV ratio, per cent shell, shell density and dead embryos than those of Leghorn eggs. 4. Lighted incubation increased daily embryonic growth (mg/d) and HP by 3.9 and 5.9%, respectively, when compared with the dark-control incubation. 5. The physical dimensions and eggshell characteristics of eggs influenced the effects of lighted incubation on embryonic growth and HP. Lighted incubation increased embryonic growth and HP of ISA-W eggs. The increase in embryonic growth and HP of the Leghorn eggs was not significant. 6. The genetic make-up of birds influenced the physical dimensions and eggshell characteristics of their eggs and these differences in the characteristics of hatching eggs influenced embryonic growth and HP when incubated under light.
