What are the prevention and control methods for sheep bluetongue disease?

Sheep bluetongue disease mainly occurs in sheep and is a viral disease with strong harmfulness, spread mainly by insects. It mainly harms the respiratory system and digestive system of sheep, and ulcer-like lesions appear at the affected sites. Because it occurs commonly and is highly harmful, it has attracted the attention of farmers. For what symptoms occur when the disease develops and the specific prevention and control measures, please read the following content.

I. Symptoms of damage

An abnormal rise in body temperature in the early stage indicates that the pathogen has already latent and is causing harm. After the disease manifestations appear, there will be listlessness, separation from the flock, swelling of the lips, saliva hanging on the face and behind the ears, and the oral cavity becoming congested and then turning blue and purple. Gradually it erodes, ulcerates, rots, and bleeds, the feet become inflamed, and movement is abnormal. In the later stage, there is emaciation and constipation.

II. Causes of the disease

It is caused by reovirus infection. Except for suckling lambs, which have a certain resistance, sheep at all other stages are very susceptible to infection and disease. It not only infects sheep, but also infects cattle and other ruminant animals. These animals can infect each other, and the virus is mainly transmitted by Culicoides midges and sheep lice flies. Hot and humid weather is the main predisposing factor for the disease.

III. Prevention and treatment

1. Seed selection and quarantine

Choose sheep with strong adaptability and strong resistance for breeding. All introduced and purchased sheep must be carefully quarantined to ensure no latent pathogen before introduction. After introduction, they should be raised in isolation for about one month and then quarantined again; after confirming there is no disease, they can enter the farm for breeding. If nearby farms develop the disease, quarantine your own sheep promptly and use medication for prevention.

2. Cleaning

Regularly clean the farm, pens, grazing areas, and other environments, and spread medicine around the perimeter to prevent various insects from entering. Also frequently wash the sheep's bodies, and perform medicated baths and regular deworming with medication; both internal and external parasites must be eliminated.

3. Epidemic prevention medication

Vaccination should be carried out before this disease occurs to prevent it. If other farms begin to develop the disease, vaccinate promptly to prevent infection. If the disease occurs, use Guohao Yangtaille and concanavalin for injection treatment together, and for severe cases add antibiotics to treat complicating inflammation.

Today we introduced the occurrence and transmission routes of sheep bluetongue disease, the symptoms for identifying it after harm, and some predisposing factors, and most importantly explained the specific prevention and treatment methods.
