What's wrong with the goat who always stands against the wall without eating grass?

I think I have sheep Japanese encephalitis.

Sheep don't eat grass and lean their heads against the wall, which is a neurological symptom, usually caused by encephalitis in sheep. The symptoms of sheep encephalitis are: rising body temperature, not eating, turning around or walking to one side, resisting obstacles. The treatment is mainly sulfanilamide combined with antipyretic drugs. Japanese encephalitis in sheep is mainly prevented by vaccine, and blood-sucking insects are one of the main transmission routes of Japanese encephalitis, so immunization is usually started in May and June every year.
