1 Overnight maintenance of pig houses intruding pigs invading pig houses will cause pig colds and pneumonia and other diseases. Therefore, pig houses should be built on a high-drying, sunny side, and must be plugged into the north, west, and east sides before winter. The window hole, timely repair of the roof and the gap between the four walls, the pigs' windows and ventilation holes should be more than 1 to 1.5 meters above the ground in order to maintain a relatively stable temperature. 2 Doors and windows of pig house hanging curtains The doors and windows of the pig house can be covered with straw mulch before the winter or the whole door and window can be covered with plastic cloth to keep warm and cold. Outside the northern wall of the pig house, a straw barrier or windrows are used to cover the wind in the northwest of the northern wall of the pig house to prevent the northwest wind from invading the pig house. 3 take plastic shed plastic shed with less investment, high efficiency, easy production and so on. Farmers disperse pigs generally according to the mode of housing, according to local conditions, because of the simplicity, the arches, ridges, umbrellas or single slope sunny sheds. On the south side, an active ventilation window is reserved for temperature adjustment and ventilation. The plastic sheds can be heated and heated to a temperature of 7°C, which is conducive to pig growth and weight gain. 4 Laying mat beds In winter, 15 cm thick corn leaves or other hay should be placed on the pig bed, which can absorb moisture, remove moisture, absorb harmful gases, and increase pig bed temperature. It has been proved that 10 cm thick sawdust is placed in the pigsty and the starter is added. After a few days, sawdust starts to ferment. The temperature can reach 35°C and the temperature in the house can be increased. Sawdust washers are good quality fertilizers for crops. 5 Let the pig sleep warm and dig a 50-cm deep flat earth pit with a layer of soft grass on it. Cover it with straw to allow the piglets to warm up inside. You can also use a straw shed to stack soft hay on the inside. Drill inside to keep warm. 6 pig house plus insulation layer Closed pig house ceiling height of 1.8 to 2 meters above the ground, add sawdust and rice husk on the shed, the ground laying grass for pig lying. A vent is left every two days in the ceiling to remove ammonia and moisture from the house. 7 Carefully feed sorghum and corn and other energy feeds should be properly added when formulating pig diets. After the feed is fermented and fed, warm water is required. The supply of feed should be adequate, around zero every night, plus one night diet to enhance the ability to resist cold and disease and promote rapid growth. 8 Adding Chinese herbal medicines can add traditional Chinese medicines that promote blood stasis, spleen dampness, and dispelling cold and dispelling cold. It can not only promote rapid fattening of pigs, but also prevent cold and prevent disease. Prescription can be used Hawthorn, Atractylodes, tangerine peel, betel nut, Shenqu each 10 grams, 30 grams of malt, Chuanxiong, licorice, Nepeta, wind, each 60 grams of borage, 8 grams of wood, into the end of the feed with a small amount of feed in the morning, Feed it once a week. 9 Increased Breeding Density Generally, the number of pigs in the house can be increased by 1/3 to 1/2 in winter, so that the pigs can warm their body temperature to each other, and if the pigs have more heat, the temperature can be increased. Pigs entering new pigs should be carried out on dark days. They should be sprayed with the wine or a low concentration of odor and then sprayed on the pigs. The keeper must observe for several hours to prevent the pigs from fighting. 10 The higher the humidity in the piggery is, the more cold the pig feels and the pig's skin, respiratory, infectious, and parasitic diseases can be easily caused. In order to prevent moisture and leakage, it is necessary to diligently change the hay and loose soil, let the pigs defecate urine, keep the pigs lying in a clean and dry place, and provide pigs with a comfortable living environment to promote winter fattening pigs. The growth and development of health.
