HATCHING CHICKEN EGGS USING COLORED LED LIGHT TITLE: HATCHING CHICKEN EGGS USING COLORED LED LIGHTS
ABSTRACT: Light manipulation has been an effective measure to improve poultry production. Providing light during incubation has been shown to affect hatchability, but the use of LED lights has not been evaluated. This study aims to evaluate the effects of using colored LED light during incubation of native chicken eggs on hatchability. To determine this, the experiment will be carried out in four groups with total number of 8 eggs (2 eggs per incubator). The eggs will be incubated 24 hours of the basic incandescent lighting (Set-up A) as the controlled set-up and 24 hours of complete colored LED lighting, Set-up B with yellow LED light, Set-up C red LED light and Set-up D with blue LED light, as the experimental groups. All groups will use 25W light bulbs. After setting the condition of the artificial environment, the eggs will be carefully monitored through the conventional way of incubating the eggs in terms of turning and candling, until the eggs reach the expected hatching period of 21 days. The results will show that there are significant effects of colored LED lighting on hatchability of native chicken eggs. There will be significant differences observed among the chick performance such as the weight, vitality and mortality of the chicks in four groups in which chick weight at hatch was the heaviest in group of eggs exposed to complete red LED lighting during incubation (Set-up C).
Design and Fabrication of Low-Cost Incubator to Evaluate Hatching Performance of Egg
European Journal of Engineering and Technology Research
In this study, a poultry egg incubator was designed, fabricated, and tested to evaluate its hatching performance. The incubator consists of a microcontroller with egg turner trays and incubating chamber of 116 nos. of egg capacity. The hatchability of the developed incubator was 79.3% and 87.1% hatchability during manual and automatic trials respectively. The temperature in the developed incubator was within the acceptable incubation temperature ranges from 37.6 °C to 38.6 °C. The average relative humidity in the developed incubator was maintained at 63.6% at manual and 55-65% at automatic trial. The eggs were turned manually approximately at 6 hours of interval. On the other hand, in the automatically controlled trial, it was done by egg turner maintaining exactly 6 hours of interval. It is noted that the percentage of hatching in rice husk incubators is below 55% which is much below comparing with the developed incubator. Also, the newborn chickens in rice husk incubators are unhe...

The thermal and luminous conditions in aviaries affect the production and quality of eggs. Thus, the aim of the present study was to evaluate the thermal and luminous environment of commercial laying hen aviaries equipped with compact fluorescent (CF) and light-emitting diode (LED) lamps and their influence on egg production and quality. The study was carried out in two commercial laying hen facilities with similar construction features and management. The first facility was illuminated with CF lamps and the second with LED lamps. The thermal environment was assessed via air temperature, air relative humidity, and enthalpy. The evaluated lamps provided a similar thermal environment in both facilities. The aviary equipped with LED lamps showed higher illuminance than the one equipped with a CF lamp. Production performance was evaluated through feed intake (FI), feed conversion (FC), mortality (M), and laying percentage (LP). Specific gravity (SG) was used to evaluate eggshell quality. The variables related to production performance and eggshell quality of laying hens raised in aviaries equipped with LED lamps were statistically equal (F-test, p > 0.05) to those raised in aviaries equipped with CF lamps. These results indicate that the replacement of CF lamps with LED lamps does not adversely affect the yield and quality of eggs.
THE EFFECT OF PHOTOPERIOD, LIGHT INTENSITY AND WATTAGE POWER ON EGG COMPONENTS AND EGG QUALITY
Abstract A total number of 840 birds were used in this experiment to study the effect of photoperiod, light intensity and wattage power on egg quality of Dandarawi chicken. The birds were classified into seven groups, (120 birds of each) two for the light intensity, two for photoperiod, two for wattage power and one as a control for all treatments. The traits studied were: Egg components (egg weight, egg shell weight, yolk weight and albumen weight): Egg quality (specific gravity, egg shell thickness, albumen quality, yolk index, yolk colour). The results obtained in this study could be summarized as follows: 1- Egg components: The egg weight decreased as light intensity increased. The shell percentage was higher by using an intensity of 60 luxes as compared with 15 and 240 luxes. The yolk percentage increased as a light intensity decreased, the opposite was observed with albumen percentage. The increase in the light intensity was associated with a decrease of maximum egg weight. Egg weight shell and yolk percentages increased as photoperiod increased, while albumen percentage decreased with increasing photoperiod. Photoperiod accelerated and increased the maximum egg weight, since it was 46.8 grams at 38 weeks and 46.1 at 40 weeks for the groups exposed to 20 and 18 hours of light. The egg shell and yolk percentages decreased and albumen percentage increased as the age increased. Such decrease continues to 38 and 34 weeks for the groups kept at 20 and 18 hours, respectively, after which there was no decrease. Egg weight decreased as the wattage power increased. The use of 200 watt lamp power as a source of light seems to be stressful for hens. Egg shell percentage was not significantly affected by wattage power but yolk percentage was significantly decreased as the wattage power increased, while the albumen percentage increased by the increase in wattage power. Egg quality: There were no significant differences in specific gravity due to the light intensity treatments. While shell thickness, yolk colour and yolk index decreased as the light intensity increased. Hough units decreased by about of 0.6 and 2.4 units for the groups exposed to 60 and 240 luxes, respectively, as compared with that exposed to 15 luxes. However, Hough unit decreased as photoperiod increased. Specific gravity and yolk colour were not affected by lamp power, while shell thickness, yolk index and Hough unit decreased significantly with increasing lamp power, this may be due to the stressful effect resulted from high lamp power. Key words: Dandarawi fowl, photoperiod, light intensity and wattage power, egg quality

Providing light during incubation has been shown to affect hatchability, but the use of LED lights has not been evaluated. This experiment evaluated the effects of LED lighting during embryogenesis on White Leghorn and commercial broiler eggs. To determine this, two experiments were conducted, the first using White Leghorn eggs (N = 3456) and the second using commercial broiler eggs (N = 3456) where eggs were incubated 12 h of light and 12 h of darkness (LED) or complete darkness (DARK); the light level was 250 lux. Hatchability, embryo mortality, and chick quality were measured in both studies, and a subset of one of the broiler egg trials were grown out to investigate fear and stress parameters. There was no effect (P > 0.05) on hatchability of layer eggs; however, there was a difference (P = 0.02) observed in chick quality, with the LED group having more chicks (75.34%) with no defects than the DARK group (56.53%). Broiler eggs exposed to LED light showed an increase in hatchability (90.12%, P = 0.03) and an increase in no-defect chick percentage (86.12%, P = 0.04) at hatch compared to the DARK chicks (85.76% and 69.43%, respectively). Differences were observed between treatments during the 14 d grow-out. The LED birds had lower (P < 0.05) physical asymmetry (0.90 ± 0.05 mm) and heterophil/lymphocyte ratios (0.279 ± 0.021), indicating that they were less susceptible to stress than the DARK birds (1.16 ± 0.07 mm and 0.347 ± 0.021, respectively). There was no difference (P > 0.05) observed between treatments in growth, FCR, or fear measures at 14 d. These results indicate that providing LED light during incubation can improve chick quality in both white layer and broiler eggs; however, it only appears to improve hatchability in broilers, which could be related to shell pigmentation. It was also demonstrated that providing LED light during incubation can reduce the stress susceptibility of broilers post-hatch. Utilizing light during incubation may be useful tool for the poultry industry.

This study was conducted to evaluate the effect of a 12-h light, 12-h dark (12L : 12D) photoperiod of green light during day 1 to day 18 of incubation time, on embryo growth, hormone concentration and the hatch process. In the test group, monochromatic light was provided by a total of 204 green light-emitting diodes (522 nm) mounted in a frame which was placed above the top tray of eggs to give even spread of illumination. No light–dark cycle was used in the control group. Four batches of eggs (n=300/group per batch) from fertile Ross 308 broiler breeders were used in this experiment. The beak length and crown–rump length of embryos incubated under green light were significantly longer than that of control embryos at day 10 and day 12, respectively…

Chick production from developing embryo is a profitable business in Nigeria due to the high demand for protein. The constant failure of electricity supply in Nigeria obstructs operation of incubator and reduce its performance. This study developed solar powered poultry egg incubator.The heat generated by 150 eggs due to the metabolic activities was 21.9W. Out of the 146 eggs loaded 64 % of the eggs were fertile while the % of chicks hatched, chicks with unabsorbed yolk, fully developed chicks but not hatched and (egg explosion) banger were 44, 40, 13, and 3 % respectively. The solar powered system proved to be a good source of power which could provide continuous supply throughout the period of the incubation without failing.
Performance evaluation of a passive solar Poultry egg incubator
Evaluation of a Solar Poultry Egg Incubator designed and developed under Makurdi's weather condition on latitude 7P o P 7′N was undertaken. The incubator had a floor area of 1 mP 2 P and a height of 2 m from the floor. The average solar irradiance per square metre of the earth surface around Makurdi, Benue Valley, on latitude 7P o P 7′N and 111 m above sea level has been determined to be 224.17 W/mP 2 P over an average sunshine hour of approximately 7 all year round. This available solar power translates to 5.7 MJ of heat energy per day, the energy value on which this design was based. The design had a means of collecting the solar energy (using plane window glass), a means of storing the collected energy (using an 80 mm concrete slab serving as the thermal mass) and a means of transferring the stored energy (using a heat exchanger and direct dissipation from the thermal mass) into the incubating chamber where the fertile eggs are to be kept for the purpose of incubation. There was also a means of supplementing the main heat storage chamber, especially during cold night hours (using granite stones). The materials were pre-treated by painting them black for better heat collection. Maximum temperature of 95 P o P C was obtained in the heat collection chamber (surface of the thermal mass). The required temperature range for incubation of poultry egg is between 37 and 39 P o P C. The incubator was tested with 125 broiler eggs obtained from a reliable commercial hatchery for fertility and hatchability. Thirty Two (32) were found to be unfertile after candling on the 7P th P , 14P th P and 18P th P day of incubation; 93 were fertile, giving a fertility rate of 74.4 %. Out of the 93 fertile eggs loaded into the incubator, 68 of them successfully hatched, giving a hatchability efficiency of 73.1%. The incubation took 21.5 days. The solar incubator can be used to hatch all poultry eggs.
