Chicken eggs are often incubated in complete darkness, obtaining light only fitfully with the incubator opening during the incubation process. There is very little knowledge available as to how light system effect on bird's production, and no data available as which light type is more energyefficient in using. Therefore, this paper offers the modification of the design for egg incubator that will be used easily, affordable and simple to maintain and concentrates on aims to give a comprehensive concept of environmental stimuli during incubation can affect the chicken production. Thus, this paper aimed at designing and evaluating the performance of a LED lighting circuit that is applied in an egg incubator, for the ability to increase the hatching rate with the lowest power consumption using a switching power supply.The present study suggests using mosfet, capacitor, and inductor for AC applications, in this circuit that is rectified the output current through a bridge rectifier as well as reduces its ripple. This current is uniform with DC applications which suits to drive LED lighting system. This is a low cost and dynamic circuit and can be used for lamps up their power 40W effectively. To evaluate the effect supplying of the lighting system during the incubation period, it was incubated chicken eggs by an amplitude of 720 eggs under variable luminous flux and different lighting periods compared with incubation in the dark. It was demonstrated that providing LED light during incubation can reduce daily power consumption compared with the other lighting systems as well reduction of the death rate of embryos post-hatch. The results obtained of the test revealed the highest hatchability proportion value was 86.88% with daily power consumption of 154.32 W under luminous flux of 700 lm within 12 h of the lighting period as compared to 77.83% which was incubated in complete darkness, The equation of the trend line related to highest hatchability percentage is The Energy Consumption =78.852 luminous power + 8.58.
Design and Performance Evaluation of an Automatic Temperature Control System in an Incubator
This paper aimed at designing and evaluating the performance of a circuit that can be used in an egg incubator, capable of controlling and monitoring of the required temperature automatically within the range of 32 to 39 C in a chamber using nonlinear sensor with possible linearization. Monitoring of temperature can be done using different types of sensors such as infrared sensors, thermal cameras, or any other alternative temperature measurement technique. This paper considers the use of thermistor due to its ruggedness and high level of sensitivity. Thermistor is a semiconductor device which senses the temperature in the chamber and the action of its output is send to a comparator which serves as a switching device in the circuit with the help of fast action of relay. The development of embryos in an incubator is highly sensitive to the environmental temperatures, studies shows that temperature manipulations around 38 C can be appropriate for hatching. The circuit consists of different stages: Power stage, stabilizing and amplifying stage, sensing and comparing stage, switching stage and loading stage respectively. All the stages work simultaneously to control the temperature in the chamber within the hatching period of 21 days with periodic turning of eggs manually. The performance evaluation and its output response show a favorable outcome as compared to standard hatching period.

Design and Construction of an Arduino Microcontroller-based EGG Incubator
International Journal of Computer Applications
Meeting the high demand for poultry products calls for the use of artificial egg hatcheries but the backyard and small-scale poultry farmers are constrained by the dependence on natural incubation or on commercial hatcheries for young birds for breeding. In this paper an incandescent bulb heat source incubator is designed and constructed to hatch 14000 quail eggs (4500 chicken egg equivalent). The incubator system is an Arduino microcontroller-based, which controls the heaters, air circulation fans and the mechanism for turning the trays, through relays. The prevailing conditions in the incubator (temperature and the humidity) are displayed on a 16x2 LCD screen. The objective of the design is to help produce a low cost, energy efficient incubator for hatching Japanese quail eggs.
Product design, prototyping, and testing of twin incubator based on the concept of grashof incubator
As the demand for prematur infant incubators are constantly high, especially in Indonesia as the fifth-ranked country of the world's most prematur baby (675,700 babies per year), the concept of grashof incubator has been developed to fulfill the needs of Indonesian citizens. As the demand grows, the need to solve twin prematur babies' problem has been emerging ever since. The designation of Twin Baby Incubator follows the basic concept of existing grashof incubator with bigger volume as a mean to include two babies at the same time. Using 3D modelling software, the product design development mainly focuses on adapting the current functionalities of grashof incubator into the twin grashof baby incubator, such as keeping the babies' cabin temperature at 33°C-35°C by allowing natural convention and natural circulation to occur. Beside the main functionalities, the design also focuses on ergonomic aspects as well as material consideration as a mean to improve usability and efficiency. Furthermore, a research was conducted to make sure that the temperature of 33°C-35°C can be achieved regardless bigger volume of babies' cabin. As the design follows the concept of grashof incubator, the main components are light bulbs as the main heater and digital thermostat as a temperature controller. DS18B20 sensors are used to measure temperature where they are being placed at ten different points of measurements, and DHT22 sensor is placed to measure the level of humidity. The expected results of the research are the capability of developed twin incubator to achieve mandatory temperature, as mentioned above, inside the cabin using 4 x 15 W light bulbs as a heater.

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.

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...
