1. Vigilance against viral diseases Winter seasonal diseases such as influenza, diarrhea, contagious gastroenteritis, and asthma are more frequent. We must immunize with important vaccines, such as epidemic diarrhea and transmissible gastroenteritis, such as double vaccines, swine fever, and pig asthma, and control the immunosuppressive diseases on farms.
2, good respiratory disease prevention Pig respiratory disease clinical manifestations of pneumonia symptoms, pigs showed cough, increased eye and nose secretions, increased respiratory rate, body temperature, mental depression, loss of appetite, slow growth or stagnation, etc. A stiff pig is formed. Porcine respiratory disease syndrome is usually caused by porcine reproductive and respiratory syndrome virus, pseudorabies virus, swine flu virus, Actinobacillus pneumoniae, porcine circovirus type II or one or more species or mycoplasma first invading the respiratory tract of pigs. The respiratory defense barrier, and then a variety of airborne pathogens, such as Pasteurella multocida, Streptococcus, Haemophilus parasuis, Borrelia bronchiseptica, etc., can easily enter the respiratory tract and lungs, resulting in secondary Mixed infection. The disease mostly occurred in nursery pigs and finishing pigs aged 6 to 8 weeks, causing serious economic losses to the pig industry. Immunization should be done for vaccines against pseudorabies and blue-ear disease, and drugs should be used to control infections such as mycoplasma and Haemophilus parasuis.
3, pay attention to warm to strengthen the warmth of the piggery, the timely repair of damaged housing, plastic film, the pighouse has to strengthen the warm work to carefully check the piggery pipe leaks, whether there is thieves wind invasion and so on. In addition, pay attention to ventilation while strengthening warmth, prevent the stimulation of porcine respiratory tract by harmful gases, and properly increase the supply of pig energy feed.
