When designing and building a sheephouse, it is more economical and beneficial to improve the thermal insulation capacity of the sheephouse than to maintain the body temperature by consuming feed or to ensure the temperature of the sheephouse by heating.

① Strengthen the thermal insulation design of the roof and ceiling. In the outer enclosure structure of sheephouse, the roof and ceiling lose the most heat. In order to make full use of the heat energy generated by sheep metabolism, it is of great significance to strengthen the thermal insulation design of the roof to reduce heat loss. Set insulation layer (furnace dust, sawdust, etc.). ) is an effective measure to increase the thermal resistance of roof. Roof and ceiling structures must be tight and airtight. With the development of building materials industry, synthetic materials used for ceiling insulation include glass wool, polystyrene foam and polyurethane board. Setting a canopy in cold areas can reduce the net height of the sheep shed and help to increase the temperature in the shed. Clear height of 2 ~ 2.8 meters tends to be used in cold areas.

② Strengthen the thermal insulation design of the wall. The wall is the main enclosure structure of the sheephouse, and the heat loss is second only to the roof. If hollow bricks are used instead of ordinary red bricks in wall construction, the thermal resistance of the wall can be increased by 41%; However, the thermal resistance of aerated concrete block can be increased by 6 times. The thermal resistance of the wall will also be greatly improved by using hollow wall or filling thermal insulation materials in the hollow.

③ Door and window design. There are fewer doors and windows on the north and west walls in cold areas, so it is important to strengthen the thermal insulation of the north and west walls, and to add door buckets, double windows or temporary plastic films and curtains to the outer doors. These are all important measures to strengthen the thermal insulation of sheep houses in winter.

④ Thermal insulation design of the ground. The treatment of the ground in the sheephouse directly affects the sheep's health. Compacted soil and concrete floor have good thermal insulation characteristics under dry conditions and are suitable for sheep houses. The cement floor has excellent characteristics such as firmness, durability and impermeability, but the cement floor is hard and cold, which is not good for sheep in cold areas. It needs to be paved with wooden boards, straw mats or stable mats. The dry wooden board is an ideal warm ground-animal bed, but in fact, when the wooden board is laid on the ground, it often absorbs water and becomes a good heat conductor, which is very cold and not strong. Grass bedding can not only improve the warm conditions of cold and hard ground, but also form a warm microclimate around sheep. Straw mats are also moisture-proof measures. However, due to its large volume and heavy weight, bedding grass is difficult to be used for industrial sheep raising. In order to overcome the shortcomings of cold and hard concrete floor, rubber or plastic stables can be used to improve the heat insulation performance of the floor.

⑤ Choose the form of sheephouse which is beneficial to heat preservation. The form of sheephouse is closely related to thermal insulation. Under the same thermal design, the heat loss of long-span sheephouse and round sheephouse through the external structure is small, and the building materials used are also economical. At the same time, the sheep shed has a large effective area and high utilization rate, which is convenient to adopt advanced production technology and technology to realize the mechanization and automation of animal husbandry production process.

⑥ Dehumidification and moistureproof. Taking all measures to prevent indoor humidity is an effective method of indirect heat preservation. Because the thermal conductivity of water is 25 times that of air, the thermal conductivity of wet air, wet walls, floors and ceilings is often several times higher than that of dry air and walls, which will reduce the thermal insulation capacity of sheephouses. The increase of water vapor content in the air in the sheephouse will greatly improve the conduction and heat dissipation of the sheep and aggravate the heat consumption of the sheep. Because the indoor air humidity is high, it has to be eliminated by increasing the number of air changes, which is bound to be accompanied by a lot of heat loss. Therefore, the design and construction of sheep houses in cold areas should not only take strict moisture-proof measures, but also reduce the water used for feeding management as much as possible, and at the same time strengthen the cleaning of sheep houses and the discharge of feces and urine to reduce the generation of water vapor.

⑦ Increase the feeding density. Under the premise of not affecting the feeding management and the sanitary condition in the house, appropriately increasing the feeding density of sheep in the house is equivalent to increasing the heat source, which is an effective auxiliary cold-proof and heat-preservation measure.

(8) Strengthen the maintenance of sheep shed. Before entering the winter, we should make preparations for wintering and keeping out the cold, including sealing doors and windows, setting up wind-proof walls, and plugging gaps and holes between walls and roofs. These measures have played an important role in improving the cold-proof and heat-preservation performance of sheephouses.

(2) heating of the sheephouse

In cold winter, it is difficult to ensure the appropriate temperature for sheep only by building insulation. Therefore, heating equipment must be used, especially in sheep delivery rooms and sheephouses. Sheep houses generally use local heating, and heat energy is generated by stoves (including firewalls and earthworms). ), electric heater, hot umbrella, infrared ray, etc. And supply it to one or several sheepfolds.
