Technical Field
The invention relates to the field of pig raising equipment, in particular to a novel pigsty based on a double-channel ventilation system.
Background
Along with the improvement of living standard of people, the demand of meat products increases, the pig raising industry develops rapidly in recent years, in the breeding process, the ventilation setting of a pigsty is an important part, the growth and health of pigs are affected by the quality of ventilation, and the ventilation type of the pigsty at present mainly comprises two ventilation modes of natural ventilation and mechanical ventilation. The natural ventilation has the defects that when the pigsty is ventilated in winter, wind directly enters the pigsty from the outside of the pigsty without preheating, and when the temperature is low in winter, cold air directly enters the pigsty to form harmful wind and blow the harmful wind onto the pig body, so that the pigsty causes wind cold to catch a cold, and when the temperature is high in summer, the ventilation effect is poor. The mechanical ventilation has two common modes of positive pressure ventilation and negative pressure ventilation at present, and also has some defects, such as higher equipment installation cost, high energy consumption required by ventilation, unobvious cooling effect in high-temperature summer seasons, difficulty in controlling harmful wind in winter and easiness in aggravation of pig cold stress. In addition, leaks still exist in many details, for example, ammonia at the bottom of the dung ditch is diffused into the pigsty, the fan cannot effectively take away the ammonia at the bottom of the dung ditch in the pigsty, the overall growth environment effect in the pigsty is poor, and a certain influence is caused on part of the pigsties.
