Farm Goat Caprine Arthritis Encephalitis: Chronic Disease Welfare

Caprine arthritis encephalitis is a widespread viral disease in goats causing chronic painful arthritis, wasting, and neurological disease with significant welfare implications.

Key Facts

CAE virus infects a majority of goats in many commercial herds worldwide
The disease causes progressive joint swelling and arthritis causing chronic pain
Affected goats show stiffness, reluctance to move, and weight loss from chronic pain
There is no treatment or vaccine — prevention relies on preventing kid exposure to infected milk
Kids born to infected does must be separated at birth and fed heat-treated colostrum
Accreditation programs that test and cull positive animals can achieve herd elimination

Welfare Considerations

CAE represents a chronic welfare burden affecting goats for years. Arthritis pain is constant and progressive, affecting quality of life across the animal lifetime. Goats with advanced CAE struggle to move, compete for feed, or engage in normal social behaviors. The pain is real and measurable, yet management has historically focused on productivity impacts rather than welfare outcomes. Clean herd programs that prevent viral transmission represent the most effective welfare intervention, requiring commitment from producers but eliminating ongoing suffering at herd level.

What You Can Do

Support goat welfare certifications that require CAE testing and clean herd status
Choose goat products from farms participating in CAE accreditation programs
Advocate for mandatory CAE testing requirements in commercial goat production
Reduce goat product consumption to lower demand from intensive operations
Support veterinary research into CAE vaccines and treatments
