The cold wind is raging in winter, the temperature difference between day and night is large, and there is a lot of heat loss in sheep, which coincides with the pregnancy period of most ewes. during the first overwintering period of breeding sheep, the demand for nutrients of sheep increases. Once raised improperly, sheep are easy to lose weight.

Sheep breeding in captivity

Sheep shed building requirements:

Choose the location. Sheep like to be dry and afraid of moisture. When building a sheep house, you should choose the leeward to the sun, the terrain is high and dry, and the soil drainage performance is good. At the same time, there should be clean water nearby, preferably green grass. The breeding area is far away from the residential area, and strict isolation measures are taken, and disinfection pools are set up at the entrances and exits of the farm area.

Basic building requirements. Moderate area: sheep are not crowded in the shed and can move freely. Generally, each breeder ram occupies 1.5 square meters, ewe 0.8 square meters, pregnant or lactating ewes 2 square meters, and young sheep 0.5 square meters. Local materials: materials can be made of hollow bricks, red bricks, steel frames, wooden sticks, cement rods, mud tiles, etc., subject to firmness and durability. Ventilation and light transmission: the window area is not less than 1 / 5 of the sheep house area. The sheep house can be opened to the sunny side. Heat preservation and moistureproof: the temperature of sheep house should not be lower than 0 ℃ in winter, and that of lamb house should not be lower than 10 ℃. The ground inside the sheep house is 20cm higher than the ground outside the shed.

Type of sheephouse:

A single-slope sheephouse. Simple sheep shed, suitable for small-scale sheep breeding area. The rear wall of the sheep house is 1.8 meters high and a playground is set up in the sun. The floor of the sheep house is 20cm to 30cm high, laid on a gentle slope, and kept dry. In winter, spread the bedding grass and change the sun frequently.

Elevated sheep barn. This kind of sheep house has higher requirements and is suitable for large-scale sheep breeding areas. The sheep house is a double-slope type with a height of 2.5 meters, with an internal walkway and an external sports ground. In order to keep the house dry and clean, the bottom of the elevated ring can be set at 50 cm above the ground. The bottom of the ring is made of steel bar and cement top into a grid type. A gap of 1 cm to 1.5 cm is appropriate for fecal discharge. A slope can be set up between the playground and the ground in the house (the slope ratio should not be greater than 1 to 2) for sheep to enter and leave freely.

Sheep shed facilities:

Sports Ground. Located in the sunny side of the sheep house, the area is 2 to 3 times larger than that of the sheep house, requiring dry ground and convenient drainage. Sheep lively love to climb high, can set up a high platform.

Feed trough. Sheep like to be clean and do not feed on ground grass or dirty grass. In order to reduce waste and make rational use of forage, a feed trough can be set up, suspended on the wall or placed on the floor of the house, and the height of the trough should be level with the back of the sheep.

The water is bad. In order to ensure an adequate supply of clean drinking water, a drinking sink can be set up in the playground, which can be made of brick and cement. At the same time, in order to facilitate cleaning and changing water, drainage holes should be set up.

Isolation house. Special isolation sheds should be built and kept at a distance from the sheephouses. After falling ill, the sheep are promptly put into the isolation house for observation and treatment, and then return to the herd after being cured. The newly purchased sheep are also raised in the isolation house in order to prevent the spread of the disease. After a period of time, it is determined that there is no epidemic disease and then return to the group. Sheep should be disinfected before and after entering and leaving the isolation house.

Prepare enough concentrate roughage. A large amount of coarse fodder such as corn straw and rice straw should be stored and utilized. The technology of crushing and processing bacterial enzyme compound biological preparation was adopted to improve the nutrition and utilization rate. Change the way "eating bones" and "eating noodles", that is, whole bundles of corn stalks and piles of hay are thrown into the sheepfold for feeding. If the number of sheep is small, you can put the grass in the basket, and then hang the basket for feeding; when the number of sheep is large, you can make a grass rack to feed the grass, and you can also tie up the grass and hang it at a height where the sheep can eat.

Supplementary feeding of sheep

Timely supplementary feeding:

In the withered grass period in winter, it is difficult to meet the nutritional needs of sheep by grazing alone, and it is suitable for half-day grazing and half-day supplementary feeding. In this way, it can not only reduce physical exertion, but also help to keep fat and gain weight. Ensure normal pregnancy, lambing, lambing and growth of sheep. Concentrate reference formula: corn flour 60% 70%, bran 10% 20%, meal 10% 20%, prepared concentrate an adult sheep fed not less than 600 grams per day, in addition, attention should be paid to the addition of salt, vitamins and trace elements; green and succulent feed such as carrots should also be added to lambs, breeding rams and pregnant ewes.

Adjust the sheep in time:

Bad weather in winter, poor feeding conditions, poor living environment of sheep, old, weak, sick and disabled sheep should be eliminated in time in order to reduce the pressure of feed management, reduce loss and improve the level of production.
