Architectural Design of Pigsty With Heat Resistant and Temperature Preservation and Fly Prevention

Using brick, tile, cement, reinforce bar and plastic film or sunshade net construct doublerow fatten pigsty and singlerow breeding pigsty which are low costly and can keep warm in winter, prevent heatstroke and fly in summer. During the winter time, the temperature inside can reach 10 ℃ without heating. While in summer time it is 3 to 5 ℃ lower than the temperature out of pigsty.When the temperature reachs 35 ℃ or more,using spraying or water drops to lower temperature.Breeding and reproduction can be done in this simple pigsty all the year round and 3 batches of finishing pigs can be produced in a year. The cost of fatten pigsty is about 80 to 100 yuan per square meter, while sow pigsty is about 100 to 150 yuan per square meter, which are very suitable for lowprofit pig raising in Shandong rural areas.
