ABSTRACT:
A method is disclosed for providing a poultry house or other livestock enclosure with an environment favorable for animal growth and unfavorable to propagation of microorganisms which includes starting the grow out cycle with the birds confined to about one-quarter of the enclosure and expanding the area with increasing body weight while keeping the body weight to area at least one pound per square foot; injecting tempered outside air mixed with inside air through an air jet device into said enclosure at a temperature below enclosure air temperature and at a velocity of about 10,000 cubic feet per minute with intermittent operation having a maximum duty factor of about 0.4 and a periodicity of about ten minutes. When outside air temperature is below 30.degree. F. the effective area for egress of air is reduced by closing the poultry house curtains to produce a slight positive pressure during air injection; air is circulated within the house intermittently or continuously by fans mounted near the peak of the roof and directed lengthwise of the house; the duty factor of the air injection process is increased as total body weight increases and volume of injected outside air is reduced for lower outside temperatures.
