A local semi-mechanical incubator was developed to hatch some kinds of poultry eggs with the purpose of decreasing egg losses and increasing incubation efficiency. A comparative study was conducted on the performance of the incubator before and after development. Performance was investigated as a function of change in temperature, relative humidity , number of turns and kind of egg in terms of hatching ratio , loss ratio and hatching cost . Experimental results revealed that hatching ratio and hatching cost were in the optimum range with the use the developed incubator under the following conditions : §Temperature of about 37.5 C , relative humidity of about 55% and number of turns of 12 times per day . §Improvements lead to of increasing of safety factors and professional integrity for laborer and detecting any shortcoming in components of the incubator electricity circuit.
Summary in Arabic.
Poultry--Hatcheries.
Poultry--Feeding and feeds.
Electromotive force.
Eggs.
Humidity.
Poultry--Effect of global warming on.
Agricultural machinery.
