摘要
雁门关寒冷地区应用暖棚养羊,可以保持适宜的温热环境,显著提高生产效率。暖棚的设计决定其采暖性能,通过不同屋面角设计暖棚,并比较其温热特性,以及暖棚对肉羊生产性能的影响,结果表明,屋面角为60°和50°的暖棚均有较好的采暖功能,50°屋面角暖棚温热环境稍次于60°屋面角。雁门关地区最佳屋面角应为60°。
Raising sheep in warm shed will maintain appropriate hypothermic surrounding and improve production effectiveness in cold areas.Heating performance of the warm shed is affected by its design.Warm sheds with different angles between warm shed and ground were designed to compare the effect of hypothermic performance and production performance to mutton sheep.Results showed that both the warm shed of 60° and 50° were good for heating.And the effect of 60° angle was better than that of angle 50.So the most suitable angle between warm shed and ground in Yanmenguan area is 60°.
