Solution: Purchase goats from herds tested negative for Caprine Arthritis Encephalitis (CAE) and Caseous Lymphadenitis (CL), and perform periodic testing on your own herd.
Explanation: CAE is a retrovirus causing arthritis, pneumonia, mastitis, and encephalitis. CL is a bacterial infection causing abscesses in lymph nodes and organs. Both are contagious and difficult/impossible to cure. Prevention through testing and biosecurity is key.
Notes: Consult a vet about testing protocols and biosecurity measures.
