(1) General requirements for sheep houses: The choice of sheep house location can be based on specific needs. Larger sheep breeding farms and finishing farms should choose places where the land is high in dryness, crowds are not crowded, there is no environmental pollution, and forage feed supply is convenient. In addition, consideration should be given to whether transportation is convenient and whether the water source and water quality are good. Depending on the condition of the house, suitable arrangements should be made under family-fed conditions. The sheep house should be spacious, otherwise the air is dirty and wet, and the phenomenon of individual sheep eating less than a few sheep will occur, affecting growth. The average area required for each sheep, adult sheep is about 1,6 to 2 square meters, bred sheep is 1 to 1,2 square meters, the area occupied by pregnant sheep, breast-feeding goats and rams, should be more appropriate. Shed height is generally 2, 3 ~ 2,5 meters. The building of the sheep building must take into account the warmth of winter, but also pay attention to ventilation and summer heatstroke. Shelter doors should be appropriately wide enough to prevent sheep from entering and entering the crowded areas, resulting in miscarriage of ewes. The width of the door is generally 1, 5 to 2 meters. The sheep house floor should be more than 20 cm above the ground outside the house so that the sheep collar can be dry and no water can accumulate. Building materials can be made on the spot, with the principle of durability. (2) Types of sheep houses: The architectural form of the sheep houses can be determined according to specific conditions, and it is not necessary to require them all. Because of the adaptability of Small Tail Han sheep, both house feeding and half-house feeding can live well. At present, pre-production is more popular in the following categories: 1 Houses circle: The house is surrounded by rectangles with a ridge at the center of the roof, steep slopes on both sides, and bricks, stones, or earthen walls. The doors should be located in the south or North, and to install a door more than 1.2 meters wide. The window on the south side wall should have a large area and a large quantity. The north wall can only have 1 to 2 small windows. Such a shed circle can be airy and light and cool in the summer, and sunny and sunny in the winter, which is conducive to keeping the sheep body healthy. 2 Houses open-air combination circle: In the outside of the house, there is another open-air ring. The house part is shaded and kept warm to provide rest for the sheep: The open-air circle is sunny enough for sheep to be transported to and received sunlight. This ring is suitable for constant feeding of sheep. 3 Rectangular sheep houses: This is a form commonly used in China, but its internal layout, structure, and setting of sports grounds are different due to the different feeding areas and feeding methods. In places where grazing is a major priority, sheep only spend the night in the open air. They only rest in sheep sheds during the winter and spring gestation and lambing periods. Drinking and supplementing are usually carried out in the stadium. The equipment in the sheep shed is very simple. During the feeding period or in the sheep farms mainly for house feeding, sheep are mostly housed in sports grounds, and there should be fixed grass racks, feeding troughs, drinking troughs, etc. in these sheep farms. The rectangular sheep-raising sheep houses are mainly double-rowed, and if they are double-headed, they are aisles in the middle, and then fixed feeders with neck ridges are built on both sides of the walkway; For tail-type sheep houses, the walkways, feeding troughs, and neck ridges should be on both sides of the window. The walkway should be paved with cement and masonry. In order to ensure the amount of sheep's movement, there should be a playground equivalent to 3 to 5 times the size of the house and shaded facilities. 4 Single Shed: Shepherd stays in the sheep shed only during rest or bad weather. Grass feeding and feeding are carried out in the stadium. This type of sheep shed is mostly used in warm areas. The front of the sheep shed is open and the rear wall has windows. 5 Sheds combined with sheep houses This type of sheep houses can be roughly divided into two forms. One is to use one side wall of the original sheep house to complete a sheep shed with three walls and open fronts. The sheep usually stay in the shed for the night. In the winter and spring lambing period, it enters the sheep house; the other form is a wall with three sides, and the side of the sunny sheltered side is a 1.0-1.5-meter-high wall, the lower wall is open, and the outside is a sheep shed on the playground. It only stays on the playground and enters the shed during the winter and spring seasons. This kind of shed combined with sheep houses is suitable for warm winter springs. 6 Shelter Shelter: This sheep home is essentially a more convenient and functional shelving combined sheep home. This kind of sheep house can be used as the sun in the winter and spring seasons to increase the temperature of the night sheep house and avoid the danger of pregnancy and the lambing ewe being affected by the cold. This type of sheep house can be based on the original three-storey walled shed. It is a low wall about 1.2 meters high along the 2 to 3 meters from the front room of the shed, and a width of about 2 meters in the middle of the low wall. The door, the top of the low wall and the edge of the shed were supported by wood or wooden frames, covered with agricultural film, and fixed with wooden slats, and the door was covered with a curtain. In the east and west walls, an air intake hole can be opened or closed at a distance of 1.5 meters from the ground. At the top of the roof, two adjustable exhaust windows with the same aperture as the air intake hole are also reserved. When the winter temperature falls to 0 to -5°C in the north, the temperature in the greenhouse can increase 5 to 10°C higher than that in the greenhouse. When the temperature falls to -20 to 30°C, the temperature in the greenhouse can increase compared to the temperature outside the greenhouse. 20 °C or so. The greenhouses with greenhouses for greenhouses also have solar energy sheds that use steel skeletons as the main body, walls, and all parts. Regardless of the form, attention should be paid to opening the air inlet, exhaust window, and lap door before the grazing, and then close the shed door and the air inlet and outlet at noon to increase the shed temperature. Because the agricultural film is easy to age, it should be promptly repaired, and attention should be paid to the timely cleaning of the ground in the shed, dry soil, and keep the shed and the ground dry. The size of the shed depends on the number of sheep, and each ewet averages about 1 to 1.2 square meters of shed area.
