北方冬季气候十分寒冷,畜禽舍内保温和通风换气一直是重点解决的问题。为了降低冬季猪舍保温取暖成本,多数猪舍通风换气不足,致使猪舍内空气环境较差,对哺乳母猪、仔猪健康发育影响较大,冬季仔猪易发或多发呼吸道疾病。为了解决北方寒冷季节猪舍内环境恶化问题,笔者针对猪场猪舍没有窗户或虽有窗户,但窗户太小、太少,夏天不利舍内通风降温的问题[1],并充分考虑猪舍在有利于猪生产的同时,冬季能防寒保温,夏季能防暑降温[2],设计了一
The winter climate in the north is very cold. The insulation and ventilation in livestock houses have always been the key issues to be solved. In order to reduce the heating and heating costs of winter pigsty, most pigsty ventilation and lack of ventilation, resulting in poor air environment within the pigs, lactating sows and piglets greater impact on the healthy development of winter pigs prone or multiple respiratory diseases. In order to solve the problem of deteriorating environment inside the pigs in the northern cold season, the author did not have any windows or piggybacks on the pig farm but the windows were too small and too small. In summer, In favor of pig production at the same time, the winter cold-proof insulation, sunstroke cooling in summer [2], designed a
