Beware of porcine dermatitis and nephropathy syndrome in summer
With the weather warming, mosquitoes increased, a number of farms in different parts of the pig skin, acute red, pink or purpuric rash, and scabies mite dermatitis, allergic dermatitis, exudative dermatitis and pig pox and other significant the difference between slow growth often leads to pigs, feed conversion decreased mortality.Porcine dermatitis and the disease known as nephrotic syndrome, occurred in the hot summer, other seasons was sporadic, often with other diseases such as eperythrozoonosis, streptococcus and other mixed hair.
Clinical symptoms
Pigs skin-like papules scattered spots, red papules began to develop into round or irregular bulge, red, purple lesions, followed by the center of the black and gradually extended to the whole of pimples, lesions occurred mainly in the back , hips and sides, and can be extended to the lower abdomen, and forelimb, serious coverage throughout the body. Ectoparasites (scabies mites) infection serious pig disease symptoms are relatively severe; individual swine fever, loss of appetite, progressive weight loss, shortness of breath, or even failure.Mild symptoms may gradually recovered after 1 week, severe symptoms usually die within 3 days, there are some diseases in clinical symptoms after 2 to 3 weeks before death.
Pathological changes
The main disease generally occurs in the skin and kidneys. Necropsy common hemorrhagic lymph nodes, kidney early swelling, khaki appearance anemia, renal cortical thinning fragile, advanced texture firm, renal capsule more difficult to peel through the renal capsule can not see the size of the surface 1, gray necrosis; pericardial effusion, cardiac soft; lung shows interstitial pneumonia, lobar pneumonia and other diseases; individual shows intra-articular bleeding. Changes in renal disease as the main basis for diagnosis.
Cause
Pathogenic porcine dermatitis and nephropathy syndrome by porcine circovirus disease (PCV-II), a disease caused, the current lack of effective vaccines to prevent infection of PCV-IIR. In addition, the blue ear virus, Actinobacillus pleuropneumoniae, Streptococcus, etc. can lead to the occurrence of porcine dermatitis and nephropathy syndrome in children (piglets - s.s. edit) after weaning multisystemic wasting syndrome related.
Mycotoxin long-term ingestion of mycotoxin pigs, the body's immune function and reduce resistance, but also more prone to this disease.
Poor conditions of stress factors in pig breeding, pig and mixed group of frequent transfer bar, pig breeding density, high humidity and temperature of pig, the incidence of ventilation can all increase.
Precaution
Strengthen the feeding and management as to minimize stress factors in the heat, ventilation, weaning, immunization, children pig castration, pig transfer bar, high density crowded, multi-dimensional in the water to add, reduce stress, enhance the body resistance force.
Strengthening environmental clearance of weeds around homes, alternating regularly disinfected, strengthen disinfection of pig farm environment and anti-mosquito efforts will focus on pigs isolated from healthy pigs in place for feeding and treatment.
Regular deworming good work
Add mycotoxin treatment agent in the disease period of high humidity and the rainy season or high season, the feed should be added to mycotoxin treatment agent, the general can only mycotoxin adsorbent adsorption of aflatoxin, it is best to use some new broad-spectrum mycotoxin treatment agent, both degradation of mycotoxins, but also a variety of adsorption and promote pig growth and mycotoxin, to prevent mycotoxin damage the health of pigs, and regularly add acid preparations to inhibit the growth of mold.
Drug therapy
Strengthen disinfection compound aldehyde, 100 poisoning, quaternary ammonium salt, organic chlorine and pig sick pig sprayed, 1 to 2 times daily for 7 days to 10 days. During the onset of all the pig and disinfect the surrounding environment, at least by two kinds of disinfectants and disinfection are two ways to turn disinfected to prevent drug resistance of pathogenic microorganisms.
Dietary anti-virus I, powder (2 bags per tonne) and 70% water-soluble amoxicillin (250 g per ton) + Houttuynia (3 kg per tonne), once a 10 days to 15 days, while doing pig insect group work, in feed dry two Iraqi net, 500 grams per ton to remove parasites in vivo.
More serious symptoms of pig, recommended amoxicillin + powerful injection + Qingkailing Houttuynia injection with dexamethasone, mixed intramuscular injection, once a day for 3 days; while pigs Victoria water (bottle versus 1 liter of water) for 5 days, suffering from pig skin spots will gradually disappear, this program can effectively control the disease.
