Abstract

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 energy-efficient 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.
