![]() 1 The incidence in Boer goats is unknown, as no CAE surveys have been conducted since their release from quarantine into Australia. The incidence of CAE in meat and fibre goats in Australia appears to be low and CAE has not been demonstrated in Australian Rangeland goats. A significant percentage of a herd may thus be infected before clinical signs become evident, and some carriers never develop signs, so infection rates may be under-estimated.ĬAE is present in the Australian dairy goat industry some producers have successfully eradicated it from their herds, however infected dairy goat herds remain in production. CAE is a slow virus and clinical signs are usually not evident until after the first kidding i.e. Infection generally occurs immediately after birth via ingestion of colostrum. ![]() The World Organisation for Animal Health (OIE) requires 6 monthly reporting of CAE and MV incidence.ĬAE is spread by body secretions and is present in blood. MV can affect both sheep and goats and causes chronic pneumonia and nervous disease.ĬAE is widespread in the developed world, and is present in Australia. Due to their similarities, these diseases have been classified together as Small Ruminant Lentiviruses (SRLV) since the early 2000’s.ĬAE, also known as Caprine Retrovirus or “Big Knee”, causes chronic peri-arthritis in multiple joints of adult goats, encephalitis (mainly in kids), chronic mastitis (also called “hard udder”) and wasting. BackgroundĬaprine Arthritis Encephalitis (CAE) and Maedi Visna (MV) are diseases caused by lentiviruses from the retrovirus family. The Goat Health Statement and National Kid Rearing Plan will function as Caprine arthritis encephalitis risk-minimisation strategies. A single national eradication strategy should be developed by the goat industry groups in Australia, and veterinarians should be involved in all stages of the program. ![]() Caprine arthritis encephalitis should be considered by the Animal Health Committee for classification nationally as a notifiable disease.
