The Central Meteorological Observatory continued to issue Blizzard blue warnings at 06:00 on December 2. At 0800 hours on the 3rd and 8:00 on the 4th, there were heavy snowfalls in the northeastern parts of Liaoning, central and eastern parts of Jilin and central and eastern parts of Heilongjiang. Among them, eastern Jilin and southeast of Heilongjiang Blizzard is in some areas. This also raises the alarm for respiratory diseases in pig farmers. Sudden changes in temperature can easily cause various respiratory diseases. These diseases are characterized by acute onset, similar clinical manifestations, difficult diagnosis, and huge economic losses caused by swine breeding. A pig farmer understands the clinical symptoms of each disease and compares similar diseases. It is a key point for accurately diagnosing and preventing diseases. We will discuss the five respiratory diseases that are commonly occurring in winter and combine them with gems. Breeding technology for pigs in fermentation beds (click here for details) to help prevent and control farmers and reduce economic losses.

Second, the clinical symptoms of pleuropneumonia Pleuropneumonia sudden onset, short duration, morbidity and mortality are high. The incubation period varies from 1 to 7 days. In experimental infections, clinical symptoms occur 4 to 12 hours after infection. This disease has the typical symptoms of pneumonia and pleuropneumonia. There are differences in clinical symptoms and age, immune status, susceptibility, environmental stress factors, and the number and toxicity of pathogenic bacteria infections. Generally, they can be divided into the most acute type and acute type. Three kinds of subacute or chronic type.
Third, the pathological changes of porcine pleural pneumonia necropsy lesions are mainly found in the chest, with varying degrees of fibrinous hemorrhage, necrotizing pneumonia and pleurisy typical pathological changes. Most of the pneumonias are bilateral, and most of them have lesions in the heart's heart, sharp leaves, and temporal lobes, and have distinct boundaries with normal tissues. The pneumonia area on the temporal lobe is often local, with deep color, swelling, and firm quality. , Brittleness, adhesion of lung and pleura, or cellulose-like covering on the lung surface and pericardium IV. Treatment of porcine pleuropneumonia with florfenicol injection, 20-30 mg/kg body weight, 1 or 2 times per day, used in conjunction 3 ~5 d. Such as synergistic sulfamethoxazole injection or compound sulfamonomethoxine, respectively, intramuscularly, 2 times a day, the better.
V. Comprehensive control measures for porcine pleural pneumonia The disease is difficult to eradicate. Control and elimination of infections must be well controlled and controlled by animal husbandry and veterinary medicine.
5.1 Adherence to the principle of prevention as the main focus, prevention of weight, prevention of stress, and prevention and control
5.2 Enhancing Biosafety Newly introduced breeding pigs must be kept in isolation for 3 weeks without disease. The use of gems dry-sweeping fermentation bed pig breeding bacteria are beneficial functional species, can secrete catalase, urease, protease and other enzymes, the use of pig manure rapid growth, deodorizing effect is good, reduce ammonia, nitrous oxide The odor substances such as hydrogen sulfide, hydrazine, and 3-methylindole are generated and volatilized, so the fermentation bed has no odor. Reduce the generation and volatilization of odor substances such as ammonia, nitrous oxide, hydrogen sulfide, antimony, and 3-methylindole, and also effectively reduce the number of pathogenic bacteria in the environment and reduce the spread of infectious microorganisms.
5.3 Improve and strengthen feeding management Avoid crowding, reduce the breeding density of pigs, improve ventilation, do heat preservation and prevent sunstroke, limit stress changes caused by excessive changes in temperature, etc., can reduce the incidence of acute cases. The use of gems dry-fermented pigs to maintain the surface of the fermentation mattress material is maintained at more than 20 degrees throughout the year to ensure that the temperature inside the pighouse is constant from the outside world.
