Johne’s Disease Q&A for Goat …
Goat Submission Form Caprine Arthritis and Encephalitis (CAE) is a persistent lentivirus infections of goats that is economically important to the goat industry. The most common means of transmission is the ingestion of colostrum by kids nursing infected does. This means that using the same alleyways or handling equipment for infected and uninfected goats can spread disease, even if the goats never see each other.CAE is a serious infectious disease that reduces production and is a threat to animal health and welfare. The most common presentation is an arthritic form in adult goats.
In an infected doe, the virus is present in every joint, however the joints that become swollen and painful are those most commonly used. CAE may also cause mastitis or a drop in milk production. This brings us to CAE (Caprine Arthritis Encephalitis), a nervous disease in goats, first reported in 1974. There is no known treatment for CAE, so prevention is the best way to minimize the impact of this disease on your farm.The CAE virus lives within white blood cells that circulate in the blood stream to fight disease. One of the worst viruses that can afflict your goats is Caprine Arthritis Encephalitis Virus (CAEV).
This occurs when the virus affects the tissues of the brain and spinal cord. Clinically infected joints swell slowly, show no heat or pain response to touch, but are extremely painful to walk on.The second most common form of the disease is meningitis. Caprine Arthritis Encephalitis (CAE) is a progressive, debilitating, and contagious disease in goats caused by a lentivirus, meaning it is a slow growing virus, which is one of the reasons it is hard for producers to control. More research is needed on additional routes of transmission, but until the research is available, it is safest to assume that any contact with infected goats, bodily fluids of infected goats, shared airspace or ventilation, or sharing equipment with infected goats may transmit CAE.To prevent the spread of CAE in your herd you will need to control the spread of these body fluids. This form is classically associated with debilitating arthritis but can also be observed in less severe manifestations. CAE can also be spread by breeding, contaminated dehorning equipment and needles, and at parturition. Caprine Arthritis Encephalitis (CAE) is a virus that affects goats in multiple ways.
(1) CAE doesn’t kill goats directly. Caprine Arthritis Encephalitis (CAE) is a progressive, debilitating, and contagious disease in goats caused by a lentivirus, meaning it is a slow growing virus, which is one of the reasons it is hard for producers to control. Infection is widespread and arthritis in more than one joint is the most common clinical signs. Caprine arthritis and encephalitis (CAE) virus infection has emerged during the past 35 yr as a major cause of disease, primarily in European breeds of dairy goats under intensive management. The CAE virus infects its hosts for life but most infected animals are subclinical and thus never develop symptoms. It is most often seen in animals less than six months of age, and symptoms develop much more quickly than the arthritic form. In just a few weeks kids will become progressively weaker; unable to stand on the hind legs first and then on the front.

CAE is the bane of many goat producers and much emphasis is placed on raising The disease results from inflammation as immune system reacts to the virus. 2015-41595-24254 from the USDA National Institute of Food and Agriculture. The mastitic form of the disease, more often referred to as “hard bag,” usually appears in first time doelings that come in with udders that appear large and full but have no milk. This type of virus has a long symptom free incubation period followed by a gradual onset of disease, so goats can be spreading disease within the herd but not showing any outward signs that they are infected. There are five main presentations of the disease, with arthritis being the most common in Canada. Remember, it is better to ship a goat a week too early than a day too late. Pneumonic CAE: This form can be noted by a chronic cough, followed by rapid breathing, difficulty breathing in general, weight loss, pneumonia, and enlarged lymph nodes. This form seems to affect goats who are older and have been carrying the disease symptom-free for many years. Diagnosis can be made by blood testing. Also known as paratuberculosis, this infection is contagious, which means it can spread in your herd. The virus is intimately associated with white blood cells; therefore, any body secretions which contain blood cells are potential sources of virus
Ensure that CAE affected goats are culled early, so they are still fit to ship.
