我国北方地区冬季牛舍内一般不采暖,舍内温度较低。与屋面、墙壁相比较,地面的热量损失虽不算大,但由于牛体直接接触地面(如站、卧),所以地面的保温性能直接影响牛的生长发育及生产能力。舍温过低,将使产奶量下降。为了控制地面热量损失和维持一定的地面温度,地面结构应采取保温措施。在现有的畜舍中,多在混凝土地面上抹水泥砂浆,这种地面的优点是坚固耐久、整体性强、造价较低、施工方便,但这种地面吸热性强,保温性能差,会使牛体感觉太凉。造成“凉”,还有另外两方面因素,一是冬季地面下土壤温度较舍内温度低;二是由
Winter in northern China is generally not heating, the temperature is low. Compared with roofs and walls, the heat loss on the ground is not very large, but because the cattle body directly contacts the ground (such as standing and lying), the insulation performance of the ground directly affects the growth and production capacity of cattle. Too low temperature will reduce milk production. In order to control the ground heat loss and maintain a certain ground temperature, the ground structure should take insulation measures. In existing livestock houses, cement mortar is often applied to the concrete floor. This type of ground has the advantages of strong durability, strong integrity, low construction cost, and convenient construction. However, this type of ground has a high endothermic property and poor insulation properties. It will make the cow body feel too cold. There are two other factors that contribute to the “coolness”. First, the soil temperature below the ground in winter is lower than the temperature in the house;
