The core message: "In the early spring, pigs grow slowly, and the resistance is reduced. When feeding, should we pay attention to some fleas?" He said that in order to strengthen feeding and management, the key to raising pigs in early spring is to improve the pig's resistance. The method is as follows: 1. Raise the temperature of the pig house. First, the open-type pig house should be covered with plastic film, it is best to cover the double-layer plastic film. This method is suitable for fat pig houses and non-lactating sow houses. The second is the boiler-type heating supply in the sealed pig raising workshop. The third is heating heating plus electric heater, suitable for nursing sows. Second, increase the feed energy level. Adjust thinking methods, feed dry materials, drink clean warm water. Such as feeding wet material, use clean hot and cold water to mix, in order to maintain a certain material temperature, and clear the feeding trough after every food. Prevent moldy feed, pay attention to add mold agent. Third, increase the air circulation in pig houses. Due to the cold weather, the piggery is in a relatively closed state for a long time, and the air cannot be replaced in time. It is easy to cause the poisonous and harmful gases such as ammonia and hydrogen sulfide to seriously exceed the standards. Therefore, the ventilation window must be opened regularly to eliminate toxic and harmful gases. Fourth, do a good job of cleaning and sanitizing work. The piggery must be disinfected, the disinfectant may use iodine preparations, chlorine preparations and other highly effective disinfectants, and 20% of raw milk or 2% of caustic soda may be used for spill disinfection (disinfection with caustic soda is not allowed). The sheds are sterilized once a week with conventional disinfectants and can be appropriately adjusted depending on the condition of animal diseases. The feeder equipment is cleaned and sterilized once every 3 days. Doors, entrances and exits for human and animal access shall be equipped with disinfection pools or mats to disinfect carpets and be replaced at regular intervals. External workers must take strict disinfection measures when entering or leaving the vehicle. Fifth, do a good job of epidemic prevention and control work. Do a good job of immunization to prevent the outbreak of the disease. We will focus on the prevention of cold-cold, gastroenteritis and swine fever, highly pathogenic blue-ear ear disease, and foot-and-mouth disease.
