CAPRINE ARTHRITIS AND ENCEPHALITIS CODE

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. We comply with the Federal Trade Commission 1998 Children’s Online Privacy Protection Act (COPPA).CAE is a virus that affects goats.

MSU is an affirmative-action, equal-opportunity employer, committed to achieving excellence through a diverse workforce and inclusive culture that encourages all people to reach their full potential. Tattooing equipment or dehorning instruments should be cleaned when being shared between animals with animals of unknown CAEV status.

Limit contact between animals at the time of breeding as the potential for transmission during natural breeding does exist.

Negative animals should be milked first and younger animals should be milked before older animals.

Separation of positive animals must be complete.Maintain a testing program for CAEV positive does in the herd.Careful attention must be paid to achieving the proper temperatures and times. Prevent milk-borne transmission with heat treated colostrum and pasteurized milk.Prevent perinatal transmission by removing kids at birth without allowing contact with the infected doe.Michigan State University Extension recommends the following to control CAEV infection: Individuals testing positive for the CAE virus should be removed from the herd. Kids should receive only heat-treated colostrum and pasteurized milk or milk replacer if there are infected does or does of unknown status in the herd. Standard pasteurization of treating milk to 165 oF for 15 seconds is recommended for CAEV prevention. Heat treating colostrum for 60 minutes to 135 oF has been shown to prevent transmission of CAEV to kids. Pasteurized kid rearing methods are the key to eliminating milk and colostrum as a route of entry for CAEV. Even with supportive care, the encephalitic form is usually fatal.ĬAEV infection and spread may be prevented by purchasing only test-negative animals or maintaining a closed herd and removing kids from infected does immediately after birth. Although there is no specific treatment for CAEV, goats may be given supportive care including pain medication and antibiotics for opportunistic bacterial infections. Approximately 35 percent of infected goats will develop arthritis as a clinical sign during their productive lifetime.

Contact transmission between adult goats is considered to be rare except during lactation. Blood (e.g., contaminated instruments such as needles, dehorners, etc., and open wounds) is regarded as the second most common way of disease spread. CAEV is primarily transmitted to kids via colostrum in the first few feedings after birth or by comingling milk from an infected doe or does and feeding it to kids. The arthritic form of the disease is most common in adult goats, while the encephalitic form is most common in kids. Farms with both sheep and goats should incorporate both species into all prevention and control programs. CAE virus may also be spread among adult goats through contact with body secretions including blood and feces of infected goats. The disease is typically spread from mother to kid through the ingestion of colostrum or milk.

Cross-infection of sheep with CAEV and goats with OPPV can occur. Caprine arthritis encephalitis virus (CAEV) is a member of the small ruminant lentiviruses (also includes ovine progressive pneumonia virus, or OPPV, of sheep), which may lead to chronic disease of the joints, and on rare occasions, encephalitis in goat kids less than six months of age.
