Abstract

A reduced profit margin in the poultry business has brought about the demand for more efficient methods of poultry farming. A savings of a few cents per bird on the cost of raising poultry may mean the difference between profit or loss. With this is mind an efficiency study was made of three types of electric brooders. Two of these types of brooders, the infra-red lamp and the conventional electric resistance type heating element and hover, are available commercially. The portable floor plate brooder with electric heating elements was constructed for research purposes in this study. These three brooders units were tested in portable, wood constructed, shed type brooder houses. No insulation was used in the construction of any of the houses. The floor was uninsulated except for the litter that was used on the floor. Bales of straw were used to bank the outside perimeter. Inside temperature of the brooder house was therefore subject to variation of the climatic temperature. Temperature variations in South Dakota in early spring may range from as low as minus fifteen degrees to as high as a plus forty degrees Fahrenheit. Under these conditions the primary purpose of this study was to compare the heat transfer from radiation, conduction, and convection that were recorded in each of the three types of electric brooders. This meant an investigation of materials that will radiate or transfer heat by radiation. Heat changes due to the variation of radiant energy received from the sun were noted.
