依据猪趴卧、采食、排便占据舍内不同区域和寻求温热舒适位置趴卧的生物学习性，在各种简易保温猪舍的设计基础上，改单一猪舍为母猪及肥猪联合猪舍，并将猪舍外围护墙（北墙）和猪床改造成空心结构，内填充保温材料，以提高猪舍的保温性能。为防止潮湿和有害气体的增加，在塑料棚上方前檐下设换气窗，使舍内形成通过换气量可以控制温热状态的小气候。加强了猪床及围护结构的隔热性能。在北墙设有防暑通风窗。越冬时在运动场上方扣双层塑料棚。每单元舍内净面积２２ｍ２，可同时饲养６～８头育肥猪和１头带仔哺乳母猪。适合我国北方地区中小养猪场及养猪专业户养猪使用。
Based on the biological learning of lying, eating, and defecating pigs in different areas of the house and seeking warm and comfortable positions, based on the design of a variety of simple insulation pigs, a single pig house is used as a sow and fat pig combination. In the pig house, the exterior wall (north wall) and pig bed of the pig house were converted into a hollow structure filled with insulation material to improve the insulation performance of the pig house. To prevent the increase of humidity and harmful gases, a ventilation window is installed under the plastic shed above the plastic shed to allow the formation of a microclimate that can control the warm state through ventilation. The thermal insulation performance of pig beds and enclosures has been strengthened. There is a heat-proof ventilation window on the north wall. A double plastic shed is draped over the playground during the winter. The net area of each unit is 22m2, and 6-8 finishing pigs and 1 sow with lactating sows can be fed at the same time. It is suitable for the use of pigs in small and medium-sized pig farms and pig breeding households in northern China.
