One negative test result doesn’t mean an animal is negative.Ĭontrolling CAE:* If you have enough negative stock, start 2 herds- one negative and one positive herd. This time they were high so she showed up positive. Last time her antibodies were low, so she tested negative. * The most likely is that the doe has been infected with CAE the whole time, but her antibody levels are going up and down. * The doe might have been infected at the last test but she hadn’t made any antibodies yet (it can take up to 8 months to get antibodies). * It’s unlikely, but possible that the doe has been infected since the last test. My doe tested negative last time but was positive this time, how does that happen? CAE has also been found in semen, so it’s possible that a doe may get infected from an infected buck. One infected doe milking into bulk milk can infect all the kids drinking it. The major way goats get infected is by drinking infected colostrum/milk. Only a few infected animals develop clinical disease, such as chronic arthritis, mastitis, pneumonia or brain disease, but even a goat without clinical signs has a reduced productivity. Infection with the CAE virus is lifelong. ![]() (There are other diseases that can cause swelling in goats knees).Ĭaprine Arthritis and Encephalitis (CAE) is a viral disease that mainly affects dairy goats. ![]() The joint pain and stiffness increases over time until the goat often starts walking around on its knees. Typically people will notice the knees swelling up and the goat becoming lame. The severity of signs ranges from severe to very mild. Older goats can sometimes get the nervous form too, it looks like listeria- circling, head tilt. The kid is usually bright and alert and keeps eating. Initially the signs can look like a lameness. The kids become increasingly weak in the back legs until they can’t walk (over days/weeks). There are two main forms of the disease: nervous and arthritic. ![]() Goats are infected as kids when they drink colostrum from an infected doe. It is a very slow virus and signs take a long time to appear. ![]()
