A plastic shed is built upon construction. Plastic sheds were built in the pens. Plastic sheds have good light transmission and can collect heat, which can increase the temperature of Shek Kuan around 5-7°C. At the same time, plastic sheds have less investment, simple production and quick results. Farmers disperse pigs generally according to the mode of housing, according to local conditions, due to the simple, simple ridge, umbrella, arched or single-slope sunny solar plastic shed. An active ventilation window is reserved on the south side for the purpose of adjusting the temperature and ventilation, and timely ventilation and ventilation. The plastic sheds can be heated and heated to 5°C, which is conducive to pig growth and weight gain. After entering the winter, the piggery must block the wind tunnel, hang the straw curtain, and paste the windows to prevent the rat mouth, cracks, gaps, broken tops, etc. in the circle from being blown into “dragon style†and “thief styleâ€. The two guarantees are the pig house plus the insulation layer and the pig house kept dry. 1 pig house plus insulation layer. The height of the enclosed pig house ceiling is 1.8-2 meters above the ground. Sawdust and rice hulls are placed on the shed, and the grass is laid on the ground for the pig to lie down. A vent is left every two days in the ceiling to remove ammonia and moisture from the house. 2 The pig house is kept dry. The higher the humidity in the pig house, the colder the pig feels; and it can easily cause skin diseases, respiratory diseases, infectious diseases and parasitic diseases in pigs. In order to prevent moisture and leakage, it is necessary to diligently change the hay and loose soil, let the pigs defecate the urine, keep the pig lying in a clean and dry place, provide a comfortable living environment for pigs, and promote the winter finishing pigs. The growth and development of health. The three increase is to increase the stocking density, increase the number of beds and increase the number of feeds. 1 Increase the stocking density. When the stocking density is high, each pig's floor space is reduced, and when lying down, they can be warmly attached to one another. At the same time, when the pigs are kept at high density, their body heat dissipation is also increased, which is conducive to raising the temperature inside the pig house. 2 increase the bed board. In the piggy stage, where conditions permit, it is best to use warm sheets such as wood boards, bamboo boards, thick fiber boards, etc. Where there are no conditions, prefabricated cement boards can be laid. 3 Increase the number of feeds. The purpose of increasing the number of feeds is to relatively increase the feed intake to compensate for the body weight deficit caused by the body fat and muscle metabolic heat production caused by the low temperature. Where conditions permit, it is best to take free food. Feeding can be added once in the evening at regular feedings. It can increase about 10% on the basis of the original feed energy level. The big pigs are low and the pigs are high. Piglets can be supplemented with high-energy feeds for fats and oils. Big pigs can increase the amount of common energy feeds such as corn in batches. The four preventions are low temperature, bite prevention, anti-chaotic feeding and disease prevention. 1 anti-low temperature. The optimum temperature for growing pigs is 15°C-25°C, and the normal growing temperature is generally 8°C or more. In order to ensure the normal growth and development of pigs, the best way is to use warm greenhouses, which use a thick plastic film to cover the top of the circle. The cover must have a slope of about 30 degrees for easy lighting. If the temperature in the noon circle is too high, it may be vented and ventilated. If it is snowing, it should be promptly removed. 2 bite-proof frame. In order to ensure the normal growth of pigs, feeding must be complete nutrition, lack of one or more ingredients, not only slow growth, but also may bite frame "evil", especially the lack of winter green feed, "evil" appear More likely. Therefore, it is necessary to replenish a variety of vitamins, minerals, and trace elements in the feed, and to separate them into strong and weak groups. 3 prevent chaos feeding. Feeding pigs should be done with stable feeding quality and stable feeding time. Ingredients should be based on different production performance and different growth stages. Avoid sudden changes in quality. If you need to change the material, increase the amount or change the feeding time, it should gradually change. When feeding in the winter, the mixed feed is best to be fed raw and dry, and the water temperature should be around 25°C when mixing with a small amount of water. In case of thin-feeding, the feed should be warm, and less ground should be added to prevent cold and cold. At the same time, pigs have a great demand for water. If there is no water in the lap, pigs will even drink urine, which will inevitably cause digestive diseases and other diseases. Therefore, constantly provide pigs with warm, clean drinking water. . 4 disease prevention. In winter, the air temperature is low, air is dry, and pigs are easy to occur. To ensure the healthy growth of pigs, pigs must always be kept clean, clean, and hygienic. Scents should be brushed, disinfected, or spray-disinfected regularly or irregularly. Pigs need to be vaccinated and they should be prepared with common drugs.
