Before the Mid-Autumn Festival, the temperature is still high and the air humidity is high. The porcine necrotic dermatitis is very likely to occur in the pigs. Attention should be paid to treatment and prevention.
Pig necrotizing dermatitis is a chronic infection caused by necrotic bacilli that causes necrosis of the superficial tissues of the skin. It occurs in the rainy, humid, and high temperatures seasons. The necrophagous bacilli widely exist in the soil, marshland, stagnant pits, sludge ponds, etc. in nature. Usually with the personnel, utensils and outside the dust into the pig house, when the empty bar is not strict disinfection of necrosis will remain in the house, when the pig skin or mucous membrane damage, such as the pig after the transfer to each other bite or the venue When a prominent sharp object is stabbed, the disease is most likely to be infected.
Porcine necrotizing dermatitis is characterized by necrosis and ulceration on the skin and subcutaneous tissues of the affected pigs. It usually occurs in the stage of piglets and piglets, and is commonly seen in suckling pigs. It occurs in the head, face, neck, body side, and buttocks. Often start from the head, gradually spread to the body behind the pig, the affected area first appeared with blisters-like rash, a few lesions deep to the muscle layer, blisters ulceration, the formation of grayish yellow, gray brown or black scab, under the skin pus Ulcers, severely ill pigs were erected and showed a hedgehog-like appearance. The pigs did not show any itching symptoms. Severely reduce or refuse to eat, increase body temperature, weight loss, and finally die due to failure.
If you regularly strengthen prevention, the disease can be avoided. It is necessary to strengthen feeding and management, check, clear or straighten the sharp protrusions on the fences and grounds, and keep the floor and playground of the pig house clean and dry. When shearing the teeth of a newborn son, the shearing surface should be approximately equal to the gums, and it is best to polish and smooth the cut and apply a 2.5%-5% iodine solution or amoxicillin powder to the cut teeth. Frequent disease-plagued old farms must regularly disinfect the pigpen and its ground and surrounding environment with disinfectant drugs twice a week. Pigs should be coated with iodine in time after traumatic injury; toy-like items such as empty disinfectant bottles, feed bags, chains, etc. should be hung on the obstetrics or nursery bar, on the growth bar gate, or in other places, and the line of sight of the pigs should be transferred to reduce their fighting. Bite opportunities can reduce or eliminate the occurrence of porcine necrotizing dermatitis.
After discovering the pigs suffering from necrotizing dermatitis, the sick pigs should be isolated in a timely manner and treated in the far column. The diseased bar and the adjacent pig barn and its ground, ditch, etc. should be thoroughly treated with a disinfectant such as compound iodine. Pigs were sterilized twice daily for more than 1 week. For affected pigs, first remove the necrotic tissue from the wound and expose it to the red wound. Then wash it with 1% potassium permanganate solution or 3% hydrogen peroxide solution once daily. The final condition can be coated or filled with one of the following drugs: 5%-10% formalin pine oil; potassium permanganate, charcoal powder (with potassium permanganate); rhubarb lime powder (rhubarb 1 serving, 2 servings of lime, first boiled with rhubarb for 10 minutes, then mix with lime, stir well to dry, remove rhubarb, study for fines, fill); soya bean oil or various vegetable oils (after boiling, heat and in In the wound area); 30 grams of realgar, 100 grams of lime, plus tung oil into a paste (filling the wound). At the beginning of the disease, injectable dexamethasone plus penicillin plus streptomycin or vitamin C (penicillin and vitamin C are injected separately), dexamethasone plus amoxicillin can also be injected, and Flucor, oxytetracycline, enro For example, sandcastle, etc., are not effective at the late stage of the disease; at the mid-to late stage, the affected area is scrubbed with a 1:4 formalin solution.
