Severe cold seasons lasts six to seven months in most regions of Inner Mongolia. Due to the cold climate condition, the growth speed and bodyweight of sheep have decreased, the lambing rate and survival rate of the lambs have seriously reduced and the consumption of feed has increased in cage-free breeding style, which has brought huge economic loses to sheep farming in those regions. In order to prevent the reduction of sheep bodyweight and provide adequate heat energy for sheep shed, it is necessary to adopt the greenhouse sheep breeding way. However, the commonly used methods for greenhouse heating, such as wood burning, coal burning or feces burning, usually cause environmental pollution and their resources are limited. As a new energy,solar energy is one of the most abundant energy resources that can be used by human being. It is also a kind of clean energy without environmental pollution and can be developed and used wherever possible without transportation problem. The utilization of solar energy in greenhouse sheep breeding will promote the development of animal husbandry in a healthy, efficient, resource-conservational way.%内蒙古大部分地区的严寒季节长达6～7个月，受寒冷气候条件的影响，散养羊生长缓慢，饲料消耗量增加，掉膘现象严重，产羔率和羔羊成活率也受到严重影响，大大降低了养羊的经济效益。建筑暖棚不仅能提供充足的热能，还可防止羊只掉膘。但是，常用的取暖方式以燃烧木材、煤或羊粪砖为主，存在着污染环境的隐患，并会受资源短缺的限制。太阳能作为一种新能源，是人类可以利用的最丰富的能源，可以就地开发利用，不存在运输问题，是一种洁净的能源，不会造成污染和公害。因此，利用太阳能采暖和暖棚养羊能够推动畜牧业向健康、高效、资源节约的合理方向发展。
