Prevention and treatment of foot rot in sheep

Rotten hoof disease is also called inter-hoof decay or inter-toe decay. It is easy to occur in autumn. It is an infectious disease that can occur in sheep, cattle, pigs and horses. Sheep hoof rot is infectious and non-contagious, which is caused by necrotic bacilli invading the seam of sheep's hooves, causing hooves to soften and rotting wounds to produce purulent secretions. It is characterized by local tissue inflammation and necrosis. Because the disease often affects the hoof, it is called "rotten hoof disease". The disease occurs in all parts of China, especially in the vast pastoral areas in the northwest, which is often endemic and does great harm to the development of sheep.

Preventive measures of hoof rot in sheep

1. Eliminate various factors that promote the disease.

① strengthens the hoof care, often trims the hoof, avoids using sharp, hard and thorny feed, and deals with hoof trauma in time.

② should pay attention to the hygiene of the enclosure, keep it clean and dry, and don't overcrowd the sheep.

③ tries to avoid or reduce grazing in low-lying, moist areas.

2. When the disease is found in the sheep, the whole flock examination should be carried out in time, and all the diseased sheep should be separated for treatment. All healthy sheep were treated with 30% copper sulfate or 10% formalin for preventive bathing. The enclosure should be thoroughly cleaned and disinfected, and the topsoil should be removed and replaced with new soil. The feces, necrotic tissue and contaminated grass were incinerated thoroughly. Sheep with rotten hoof disease should be isolated and treated in time. Healthy sheep are kept together or grazed in the same pasture. If there are more sick sheep, the pastures and drinking places should be changed; choose high-dry pastures and go to the sandy river to drink water. Stop grazing in polluted pastures and reuse after at least two months.

3. Injection of anti-foot rot vaccine "clovax". The first two injections were given at intervals of 5 to 6 weeks. After that, it was injected once every 6 months. The vaccine works well, but 100% can only be achieved under the best management conditions. The vaccine can also be used for treatment, but its main role in the future is to take partial preventive measures and, most importantly, to be combined with good management. Because vaccines are expensive, sheep owners usually only use them for rams. For dead sheep or slaughtered sheep, the necrotic tissue should be removed first, and then skinned, waiting for the skin and hair to be dried before it can be transported.

Treatment of hoof rot disease in sheep

First of all, it is isolated to keep the environment dry. Then according to the development of the disease, appropriate treatment measures should be taken.

1. Remove the necrotic tissue. When a clean wound occurs, rinse with vinegar, 4% acetic acid, 1% potassium permanganate, 3% Lysol or hydrogen peroxide, and then bathe the hoof with 10% copper sulfate or 6% formalin. If it occurs in large quantities, smear the affected area with 10% gentian purple or turpentine every day.

2. If the abscess is not broken, the abscess should be cut and discharged, then washed with 1% potassium permanganate, then daubed with concentrated formalin, or sprinkled with potassium permanganate powder.

3. After the necrotic tissue is removed, 10% chloramphenicol alcohol solution can be applied locally with penicillin aqueous solution (100-200iu per ml saline) or oil emulsion (1000iu per ml oil). For seriously sick sheep, such as secondary infection, local administration should be accompanied by systemic use of sulfonamides or antibiotics, of which sulfadiazine or oxytetracycline injection is the best.

4. Put the gauze of formalin semen soaked 2% into the rotten place of the hoof fork and remove the bandage with medical gauze for 24 hours.

5. Purulent secretions in the hoof fork with serious illness, wash the secretions with potassium hypertonic acid solution, plug the fork with penicillin powder and bandage with gauze for 24 hours.

6. In the granulation stage, oxytetracycline and glycerol can be used at 1:10; when granulation is excessive, 10% halogen ointment or halogen powder can be applied. In order to prevent the irritation of the hard object, the diseased hoof can be bandaged.

7. Soak the affected area with 1% potassium permanganate solution for 10 minutes. Once in the morning and once in the evening.

8. After washing the rotten hoof first, wipe it with 5% iodine tincture and coat the outside with pine distillate oil. Once a day.

9, traditional Chinese medicine treatment, can choose peach blossom powder or dragon bone powder spread to the affected area, to cure sheep rotten hoof disease, according to the degree of disease, adhere to several methods to rotate several times of treatment.
