Which of the following symptoms is typical of louse infestation in livestock?
Answer Details
The symptom that is typical of louse infestation in livestock is itching of the body. Lice are ectoparasites that live on the skin and hair of livestock and feed on their blood. As they feed, they cause irritation and itching, which can lead to the animal rubbing and scratching against hard surfaces to relieve the itching. This can result in hair loss, skin lesions, and even secondary infections. While abdominal pain and profuse salivation are symptoms of other livestock diseases, oozing out of blood is not a common symptom of louse infestation.
