Treatment of suspected exudative dermatitis in a farm on a farm

When I recently visited a medium-sized pig farm, I encountered a scab in the head, ears, under the abdomen, and limbs of a newborn pig, and similar symptoms appeared in some of the adjacent pens.

Incidence

First of all, there were more than 10 pigs in a certain pen, and there were similar signs of peeling. A considerable number of pigs were more serious. The disease spread quickly to five pens. The diffusion unit showed that there were similar symptoms in 1 litter to 2 litter pigs, and it showed a tendency to spread. Dehydration occurred more severely in some individuals, but no deaths occurred.

The main symptoms

The pigs born on the second day of a litter in one of the pens were found to have similar peeling patches. The main parts were in the head, ears, lower abdomen, limbs, etc., with a diameter ranging from 0.5 cm to 2 cm. No abnormalities, followed by plaque scarring, body wasting, dehydration, superficial swelling in the lymph nodes or edema. As the disease spreads, the pigs in different fields also have different degrees of infection, showing similar symptoms.

First visit results

According to the incidence and main symptoms, it can be diagnosed as exudative dermatitis.

Cause analysis

According to the situation of the farm, the main consideration is due to lack of disinfection time (2 days to 3 days), which causes the accumulation of pathogenic microorganisms and causes the disease; sows themselves are poisoned; mosquitoes or flies in the field; personnel mobility, equipment Sharing is the cause of the spread of the disease.

Processing advice

Considering that the disease is mainly transmitted through contact, the route of infection should be cut off.

Separate the onset bar from the normal bar with insulation boards, and use tools such as brooms and normal bars separately to reduce the entry of outsiders.

Cleaning the teeth of newborn pigs, using dry, soft pig beds, can reduce the incidence. Sows should be cleaned, disinfected, and then placed in clean, sterilized, or fumigated sheds before entering the delivery room. Disinfection treatment of local lesions of sows and sows immediately helps prevent the disease.

Strengthen the deworming work of pigs: use Igan Dien (Ivermectin) spices.

Strengthen disinfection, severe barn house with body disinfection twice a day, other barn house once a day, select some disinfectant with good disinfection effect and less irritation (eg 100 toxins, 100 toxins, 2.8, 6.8);

Keep the grass in the barn dry and the pig fur dry and clean so that no dirt such as feed or faeces can stick to the coat.

Trying to extend the time of disinfection of the empty bar, one day before entering the pig, it was disinfected with imported disinfectant (Nongfu).

Treatment: 1 individual treatment: Gentamicin/Amikacin and potent amoxicillin, dexamethasone (half-branch) intramuscular injection or selective intramuscular injection of saoxins; 2 population treatment: Ginga Sulphur, kanamycin, and oxacillin drugs drinking water; 3 body surface: waste oil and sulfur or potassium permanganate rubbed; 4 After using drugs, follow-up feedback should be provided in order to use effective drugs. For those who are dehydrated, timely rehydration with oral rehydration salt, pay attention to vitamin supplements.
