1. Wind protection. In winter, cold winds intrude into pig houses. Attacks on pigs cause colds and pneumonia in pigs. Therefore, piggery should be built on a high-desert, south-facing, sunny side, with wood, straw or plastic before winter. Films and other places to block the piggery blocking the air, to prevent the intrusion of cold wind; at night in the pigskin door and window curtains to keep warm and cold.
2. Increase the stocking density. Increasing the stocking density generally increases about 40% in the winter than in the summer. The pigs increase their calories and naturally increase their temperature. At the same time, the pigs can sleep and heat each other, and they can also increase the overall temperature of the pig house.
3. Add energy feed and carefully feed. When preparing the pig's diet, the ratio of corn, sorghum and other energy feeds should be appropriately increased, or regular high-quality full-price feeds should be used for drinking warm water. The feed supply was sufficient. During the day, the number of feedings was increased. Feeding of a meal was maintained around zero at night, and pig food was dried to enhance cold-resistance and disease resistance, and to promote rapid growth.
4. Set the heat source in the pig house. Manually set the heat source in the pig house to increase the temperature in the pig house. Use hot air heaters, heaters, coal stoves and other equipment to provide the heat source, and use electric heating plates, infrared light bulbs and other heating equipment to provide extra heat for the pig incubator . In the use of coal-fired heating equipment, attention should be paid to the smoothness of the flue to avoid carbon monoxide poisoning in pigs due to poor smoke and carbon monoxide detention. At the same time, measures must be taken to prevent fire.
5. Remove harmful gases. If the concentration of harmful gases in the pig house is too high, the ability of the pig to resist disease and keep the cold will be significantly reduced. Therefore, the daily use of noon high temperature period, open the doors and windows ventilation, remove harmful gases, exchange fresh air, is conducive to the growth of pigs. .
6. Keep the pig house dry. The dangers of wetness in pig houses: First, the higher the humidity in the pig house, the more cold the pigs feel and the pigs will get together and cause crushing, crushing and even death. The second is conducive to the growth and reproduction of bacteria, can easily cause epidemics, common skin diseases, respiratory diseases, infectious diseases and parasitic diseases. Therefore, pig house drying is one of the main measures to ensure the health of pigs.
