Pathogen : The pathogen is the swine fever virus of the genus Fibriovirus, which is present in the whole body and body fluid of sick pigs, among which lymph nodes, spleen and blood contain the most poisonous substances. The virus is weakly resistant to adverse effects and is prone to death in a dry environment and some disinfectants. The diseased pig house and the polluted environment lose contagiousness after 1 to 3 weeks at dry and high temperatures. 2%~3% of caustic soda can inactivate the virus after 30min, and 5% bleaching powder can kill the virus after 1h of operation.
Epidemiology: Pigs of all breeds, ages and genders are susceptible, wild boars are also susceptible, sick pigs and poisoned pigs are the source of infection, and the virus is excreted through feces, urine and various secretions. The main routes of infection are the digestive tract and the respiratory tract. The invading portal is the tonsils, which then enter the blood circulation. The disease is highly contagious and has no seasonality.
Clinical symptoms: The incubation period is generally 5 to 10 days.
The most acute type: sudden onset, rapid symptoms, elevated body temperature to 42 ° C, extreme mental depression, lying down, sick pig skin mucosa purpura, bleeding.
Acute type: This type is the most common, sudden onset, the course of disease is 1~2 weeks, eat less or not eaten, the body temperature continues to be high fever at 40~42 °C, sick pigs chill, tweet, like to drink cold water, conjunctival flushing and inflammation, some sick pigs have nerves Symptoms, tremors, convulsions, faeces in the early stages of the disease, dry constellation, constipation and diarrhea alternately.
Acute and chronic: the course of disease is mild, the course of disease can reach 20~30 days. The pregnant sow may not show symptoms after infection, but the virus is transmitted to the fetus through the placenta, causing miscarriage, stillbirth, deformity, fetal mummification, or giving birth. The piglets were weak, tremor, and finally died.
Pathological changes: systemic lymphadenopathy, dark purple, bleeding around the cut surface, marble-like, epiglottic cartilage and laryngeal mucosa, bladder mucosa, epicardium, lung membrane, intestinal serosa, peritoneum and subcutaneous, etc. Or blood spots; kidney is yellowish, with small red spots on the surface, infarcts in the spleen, hemorrhage and necrosis in the mucous membrane of the chronic swine fever, and in the vicinity of the echogenic valve and the cecum and colon mucosa, button ulcers of different sizes can be seen. , protruding from the mucosal surface.
Prevention and treatment of swine disease : no specific drugs, strengthen prevention work, and strictly implement the vaccination program.
Plastic dimple drainage sheet is made of high molecular, produced by extrusion and adsorption. The tri-dimensional space can drain gas and fluid. It`s a multi-functional material, can from channels for water and gas easily, which is sound insulation and vibration isolation. In the field of civil construction can be widely used in building roof system layer overhead, planted roof drainage ventilation, basement waterproofing system production, thermal and moisture isolation of the interior surface, road and rail tunnel drainage protection. In the urban land, space, material resources are becoming scarce today. Plastic dimple drainage sheet to provide the most valuable option.
