As winter approaches, pig farmers face preparations for listing and breeding next year. How to get the pigs through the cold winter is crucial to achieving good production efficiency.
Feed hot food drink warm water. In winter, pigs eat on the one hand to increase body weight. On the other hand, heat energy converted from feed can resist cold. In order to meet the nutritional requirements of pigs, it is necessary to appropriately match coarse, fine, green, or mineral feeds according to different types of pigs, and feeds should be appropriately fed to feeds that produce more calories, such as corn, alfalfa, and oil cakes. Let the pig eat well. If you feed cold and cold water, it will not only consume a part of calories in your pigs, but also cause diarrhea in your pigs. The food temperature is 35 °C -40 °C is appropriate, adequate amount of feed must be put in at midnight plus a meal. Pigs have a large demand for water. If pigs do not have enough water for drinking, pigs will eat snow, eat ice cubes and drink urine. This will inevitably cause pigs to suffer from gastrointestinal diseases or other diseases. So give the pig plenty of warm, clean drinking water.
Keep warm. Suitable temperature for newborn pigs is 32°C-35°C, nursery pigs are suitable for 20°C-26°C, middle pigs and pigs are suitable for 15°C-23°C. Before the arrival of winter every year, the existing pigsty should be inspected and a plastic insulation shed can be built. When the pig house is collapsed and open-aired in a timely manner, even if there is a crack in the wall, it must be wiped with mud. Close the windows and excess ventilation holes, leaving the ventilation holes more than one meter from the ground.
The method of laying a mat bed: laying a 15 cm thick corn leaf or other hay in a sty, 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.
The high humidity in the winter pigsty not only enhances the heat of the pig's body, but also causes the disease to occur. In order to keep the pigs clean and dry, the pigs should be given regular excrement and urine. Under the premise of maintaining the temperature, increase ventilation and increase lighting.
Regular disinfection of the pigsty to prevent various common infectious diseases in winter and spring. Generally, iodophors, peracetic acid, and other disinfectants can be used to sterilize the pigs at noon on a sunny day, and the environment of the pig house is sterilized every day. The pigs can be sterilized 2-3 times per week. At the same time, do a good job of foot-and-mouth disease, swine fever, infectious gastroenteritis, rotavirus immunization.
