Winter pig keeping warm cold method
1. Overhaul of pig houses: The intrusion of thieves' winds into pig houses in winter attacks the pigs' pigs and cause diseases such as colds and pneumonia. Therefore, the piggery should be built on the terrain of high dryness and sunny, and it must be plugged in the north and west before entering the winter. The east side of the window hole, timely repair of the roof and the gap between the four walls, the pigs' windows and ventilation holes should be 1.0--l from the ground. 5 meters or more to keep the temperature stable.
2, pigskin doors and windows hanging straw: the pigs' doors and windows before the winter can take the straw curtain cover or the entire door and window covered with plastic sheeting to keep warm and cold. Outside the northern wall of the pig house, straw is used to form wind barriers or windrows on the northwest to prevent the northwest wind from invading the pig house.
3, take the 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 arched, ridge-shaped above the shed. Umbrella or single-slope sunny shed. On the south side, an active ventilation window is reserved for temperature adjustment and ventilation. The plastic sheds can be heated and heated to 5°C, which is conducive to pig growth and weight gain.
4. Laying mat beds: In the 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. According to the sawdust, it is a good quality fertilizer for crops.
5, let the pig sleep warm nest: Dig a 50 cm deep flat earth pit, which is covered with a layer of soft grass, covered with straw above, so that the piglets in the heating; also can take a straw shed, which piled on soft hay, Let the pig drill inside to keep warm.
6, pigs plus insulation: enclosed pig house ceiling height of 1.8 to 2.0 meters above the ground. Sawdust and rice hulls were added to the shed, and grass was laid on the ground for pigs to lie down. A vent is left every two days in the ceiling to remove ammonia and moisture from the house.
7, carefully feeding: In the preparation of the pig's diet, should be properly increased energy feed such as sorghum and corn. The feed is fed after fermentation and it is necessary to drink warm water. 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, add feeding traditional Chinese medicine: You can add in the feed, blood stasis, spleen dampness, cold dispelling cold Chinese medicine, both to promote the pig's rapid fattening, but also cold resistance. Prescription can be used Hawthorn, Atractylodes, Citrus, Betel Nuts, Divine Comedy each 10 grams. Malt 30 grams, Chuanxiong, licorice, Nepeta, wind, Bairen each 60, 8 grams of wood, into the end of the study mix a small amount of feed in the morning once fed once a week.
9, increase the stocking density: In the winter, the number of pigs in the house is generally increased by 1/3 to 1/2, so that the pigs can warm up to each other's body temperature. In addition, the pigs can dissipate more heat and can increase the temperature. 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 pig house is kept dry: The higher the humidity in the pig house, the colder the pig feels; and it can easily cause pig's skin diseases, respiratory diseases, infectious diseases and parasitic diseases. 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.
