MEASUREMENTS OF COMPONENT HEAT LOSSES OF POULTRY
Abstract
Scientists and engineers have long studied the problem of the heat production of animals. Their studies have, of course, been limited by the tools available and by the particular discipline of the experimenter. To further the study of the environmental offects of this problem, an apparatus and method were developed. While final solutions have not been possible, this study helps clarify the problem. and defines aspects of the problem that still must be re- solved.The apparatus developed was a gradient layer calorimeter designed to measure the component heat losses (radiation and convection) of poultry. The inside surface of the calorimeter was lined with two thermopiles, which were used to measure the heat flow. A gradient layer thermopile. was used to determine the total sensible heat. A four-p1 radiometer thermopile was used to determine the radiant component of heat loss. Air was circulated through the calorimeter to maintain normal conditions for animal metabo- lism. The inlet air temperature was maintained equal to outlet air temperature.
