Control Over Environment of Southern Layer Hen Farm

In this study, the environment of the layer hen farm is controlled by the rebuilding hencoop and the harmlessly disposing of chicken wastes. Installing ventilator and nozzle in layer hencoop and effectuating longitudinal ventilation and spray will lead to a fall of 3～5℃ in indoor temperature during the summer high-temperature season. Making chicken wastes into commercial fertilizer through fermenting and desiccation and discharging sewage after disposing and qualifying will produce good social and economic effects.
