How to treat sheep with foot-and-mouth disease? What are the symptoms and routes of transmission?

Foot-and-mouth disease in sheep is commonly known as foot-and-mouth sore and foot-and-mouth disease in folk. It is an acute, febrile, and highly contagious disease caused by foot-and-mouth disease virus in cloven-hoofed animals. Goats and sheep can all suffer from this disease, and sometimes it can be transmitted to humans. How can sheep be treated for foot-and-mouth disease? What are the symptoms and routes of transmission?

1. Occurrence of symptoms

The incubation period of sheep and goat disease is 1-7 days, with an average of 2-4 days. The main symptoms are elevated body temperature, loss of appetite, depression and claudication. Oral blisters often occur in the oral membrane, blisters on the tongue are rare, oral lesions are more common in goats than sheep, blisters often occur in the hard palate and tongue, ewes often miscarry, hoof blisters are small, not as obvious as cattle.

II. Ways of infection

The main source of transmission of foot-and-mouth disease in sheep is diseased livestock, followed by infected wild animals (such as yellow sheep), mainly through digestive tract and respiratory tract, as well as through eye conjunctiva, nasal mucosa, nipples and skin wounds. if people or healthy sheep come into contact with saliva, blisters and milk of diseased animals, they may be infected. Dogs, cats, rats, blood-sucking insects and human clothes, shoes, etc., can also spread the disease. Dairy goats sometimes see nipple lesions, reduced milk, suckling lambs are particularly prone to disease, hemorrhagic gastroenteritis, may also occur malignant foot-and-mouth disease, due to acute heart paralysis and death, the mortality rate can reach 20-50%.

III. Treatment methods

1. Strengthen nursing care of sick sheep

First of all, it is necessary to strengthen nursing care for sick sheep, such as dry enclosure, good ventilation, soft feed (such as grass, noodle soup, rice soup, etc.) and clean drinking water, and often disinfect the enclosure.

two。 Wound disinfection treatment

Wash the mouth with 0.1-0.2% potassium permanganate, 0.2% formalin, 2% potassium permanganate, 0.2% formalin, 2-3% alum or 2%-3% acetic acid, and then smear the festering surface with iodoglycerin or lactide 3% copper sulfate, or spread ice boron powder. Soak the hooves with 3% odorous potion, 3% cresol soap solution, 1% formalin or 3% 5% copper sulfate, or smear them with disinfection ointment or 10% iodine. Then wrap it with a bandage, it is best not to wash the hoof more, because dampness can hinder recovery, breast disease should be milked carefully, wash the nipple with 2% boric acid water, and then apply disinfectant ointment

3. Inject antibiotics

For sheep with malignant foot-and-mouth disease, special attention should be paid to the maintenance of cardiac function, cardiotonic and glucose injection should be used in time. In order to prevent and treat secondary infection, penicillin can also be injected intramuscularly and crystalline camphor can be taken orally. 1 gram each time, twice a day, the effect is good, and it can prevent the development of malignant foot-and-mouth disease.

IV. Preventive measures

1. Strengthen quarantine

The introduction of animals and animal products, feed and biological products from disease-free countries or regions is strictly prohibited. Animals and their products from disease-free areas should also be quarantined. when positive animals are detected, the whole group of animals shall be destroyed and disposed of. Vehicles, animal wastes and other polluters should be disinfected on the spot

two。 Strict disinfection

In the event of an epidemic in areas free of foot-and-mouth disease, decisive measures should be taken to cull and destroy all diseased animals and animals of the same group, and strictly and thoroughly disinfect the polluted environment.

3. Vaccination

In the epidemic areas of foot-and-mouth disease, animals are vaccinated with attenuated or inactivated vaccine of foot-and-mouth disease with the same type of local epidemic strain. Because the attenuated vaccine of cattle and sheep may cause disease to pigs and the safety is poor, it has been changed to inactivated vaccine of foot-and-mouth disease.

4. Report the epidemic situation in time

When foot-and-mouth disease occurs in the fauna, the epidemic situation shall be reported immediately, the diagnosis shall be determined, the epidemic spots, epidemic areas and threatened areas shall be designated, isolation and blockade measures shall be implemented, and emergency immunization shall be given to the animals in the epidemic areas and threatened areas.

The above is the introduction of the transmission route, preventive measures and treatment of foot-and-mouth disease in sheep by Tuliu.com. We must pay attention to timely detection and report of the epidemic situation.
