temperature of the chicken, which is a measure of the chicken house the

first element of the environment. (1) the parameters: ventilation in

summer peak demand calculations, 4~5 cubic metres per kilogram of body

weight per hour, harmful gas concentration does not exceed 20ppm ammonia,

hydrogen sulfide, l0ppm, co 0.15%. (2) ventilation natural ventilation

and mechanical ... 5. thermal insulation roof cold season is the region

of greatest heat loss, are also hot towel sunlight than any other region,

so the roof insulation is the most important region, followed by the

walls, if open sheds to make doors and Windows switches freely, and seal

well. On most of the walls and roof insulation must be taken or

equivalent devices, thermal insulation materials require higher thermal

resistance, good thermal insulation properties, and thicken the North

wall must also be taken of thickness and measures such as roof and

ceiling canopy. In places with more rain, due the eaves of roofs on both

sides extending outward. Pheasants (pheasants) farm building (a) site

choose pheasant fields should be selected gaozao terrain, sand texture,

well drained, slightly to the South of terrain. Mountain areas should be

selected under the sunny, spacious, ventilation, sunshine, where the

drainage is good. Pheasant farms should be built in a quiet, safe place,

away from residential areas, factories, the main traffic artery, but

taking into account feed, transportation problems. A clean water source,

water is not contaminated. To have a reliable power supply, not only to

maintain normal lighting,air, keep house air fresh, cooling, moisture,
