Final answer:
Caprine Arthritis Encephalitis (CAE) is the most prevalent disease in goat operations, causing chronic health issues such as arthritis and encephalitis in affected animals.
Step-by-step explanation:
The most prevalent disease in goat operations is Caprine Arthritis Encephalitis (CAE). CAE is a viral disease that affects goats and leads to chronic conditions such as arthritis and encephalitis. It is transmitted through infected milk and other bodily fluids. It is important for goat operations to implement strict biosecurity measures to prevent the spread of this disease, as it can have significant impacts on the health and productivity of the herd. Other diseases that may be encountered in goats include Foot and Mouth Disease, Scrapie, and Bloat, but CAE remains a major concern due to its prevalence and impact.
