How Pigs Fight Common Respiratory Diseases in Winter
Winter is a season of high incidence of porcine respiratory diseases. With the large changes in external factors (eg, strong wind, temperature difference between day and night), the risk of developing respiratory diseases in pigs increases. How to prevent the invasion of respiratory diseases in pigs in winter and reduce death losses, and save costs It is a common concern for farmers. Breeding households develop respiratory diseases at high frequency during the daily pig raising process. It is necessary to understand and master the respiratory disease and control technology in winter pigs. In this paper, data collection and collation of porcine respiratory diseases and their prevention and control were conducted in the hope of providing effective reference for farmers. (1) Multi-pathogen mixed infection. Porcine respiratory diseases are mostly caused by interactions of viruses, bacteria, parasites, environmental stress, and poor immunity in pigs. Clinically, single factors cause less pathogenic diseases, and thus show a respiratory system in pigs. The syndrome group is the respiratory disease syndrome (PRDC) in pigs. It is often a double or multiple infection between viruses and viruses, viruses and bacteria, bacteria and bacteria. Such as porcine reproductive and respiratory syndrome and multiple weaning syndrome after weaning. (2) A large proportion of porcine respiratory diseases has changed from acute to chronic, and it is difficult to eradicate pigs, becoming an often-occurring and frequently-occurring disease. The harm is becoming more and more serious. (3) The disease is complicated, serious, and the mortality rate is high, and the onset is rapid and spreads quickly. (4) Stress is an important cause. Such as climate change, pigs are overstocked, the pigs are weaned, mixed, transported, and transported in long distances. The temperature of the pig house is too large, the humidity is too high, the ventilation of the pig house is poor, and the air quality is poor (ammonia, hydrogen sulfide, carbon dioxide Too high) etc. Second, the typical symptoms: In the case of respiratory disease, the pigs have increased cough, especially when they enter the pig house in the morning. Pneumonia, mouth breathing, abdominal breathing and other different respiratory symptoms, normal or elevated body temperature, fecal softness, etc., with the climate change, respiratory symptoms also occur in varying degrees of change. If the treatment is not timely, the pigs develop high fever and respiratory symptoms worsen, the growth rate becomes slower, the pigs gradually become thinner, the back hair becomes rough, the tip of the ear becomes purple, the skin becomes red, and even the nasal cavity is bleeding and the foam is forgotten. Third, prevention and control measures: (1) Strengthen feeding and management: Feeding and management of pigs at various stages should be well done to ensure the nutritional level of the pigs and feed for mildew should be prohibited. In winter, it is necessary to do well in heat preservation and cold protection, and to ensure that the temperature is in the appropriate range, but also to do Good ventilation and work. (2) Establish a sound biosafety system: adhere to self-cultivation and self-support, establish safe and stable breeding herds, do not introduce species from areas with epidemic situation, introduce pigs to be isolated, monitored, and quarantine, and finally gregarious. The whole field must implement the all-in/all-out system to ensure at least two stages of delivery and conservation. In addition, the most important thing is to regularly sterilize the injection and the environment, separate the excreta and urine, clean it up in time, and keep the pig house, feeding and management equipment and the environment clean and hygienic. (3) Strengthen the immunization measures: The vaccine can be used in healthy pigs to produce immune protection. It must be under good husbandry and management conditions to exert the best immunoprotective effect of the vaccine. In strict accordance with the requirements of the instructions, inoculate related vaccines. It is possible to immunize sows and protect piglets with sow antibodies. (4) Drug prevention: a combination of comprehensive treatment and symptomatic treatment. Treatment should pay attention to the combination of drugs, such as the combination of antiviral drugs and broad-spectrum antibacterial drugs, the use of broad-spectrum antibacterial drugs in combination. And at any time according to the changes in the symptoms of the disease to replace the drug treatment to prevent the emergence of drug resistance. Regardless of the degree of respiratory disease in pigs, even minor illnesses cannot be ignored. In particular, pig body temperature rise, cough and other symptoms, will become the cause of many diseases, often become the "source of all diseases," if not timely control, will cause irreparable damage, so to be the main prevention, Timely discovery of timely treatment.
