Infection is widespread and arthritis in more than one joint is the most common clinical signs. Less often diagnosed are pneumonia and progressive weight loss.In CAE infected goats, symptoms typically appear around two years of age, but can appear at any time in adulthood.Goats displaying signs of CAE should be seen by your herd veterinarian. The disease results from inflammation as immune system reacts to the virus. CAE is a chronic multi-systemic disease in goats. It was named for two of the most common forms of the disease — arthritis, which usually is […] The disease is often painful and severely limits production by preventing goats from accessing feed, leading to weight loss. One of the worst viruses that can afflict your goats is Caprine Arthritis Encephalitis Virus (CAEV). The virus is intimately associated with white blood cells; therefore, any body secretions which contain blood cells are potential sources of virus The most common means of transmission is the ingestion of colostrum by kids nursing infected does. There are five main presentations of the disease, with arthritis being the most common in Canada. Most often characterized by big knees, the virus also does irreparable damage to the lungs as well and affects the immune system leaving the goat defenseless against most common ailments. 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. This form seems to affect goats who are older and have been carrying the disease symptom-free for many years. 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. CAE can also be spread by breeding, contaminated dehorning equipment and needles, and at parturition.The target tissues of CAE virus are the joints, mammary glands, lungs, and brain. However, a minority of infected animals will develop progressive, untreatable symptoms including Diagnosis can be made by blood testing.
CAE is easily spread, and healthy goats can be carrying the virus.Ontario Goat represents Ontario’s milk, meat and fibre goat farmers with a united voice and is dedicated to enhancing the goat industry through education, collaboration, innovation and strategic alliances.Proudly representing Ontario's dairy, meat and fibre goat farmers with a united voice 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. The virus can survive outside the body until the fluids have dried up, meaning if a goat coughs and leaves mucous on the wall or drops milk or birthing fluids on the floor it has the potential to infect goats for several hours.
All breeds of goats are susceptible to this retrovirus, and prevalence of infection is related to exposure to virus. Johne’s Disease Q&A for Goat …
The udder will not be hot or painful, but is quite firm to touch.
Infection is widespread and arthritis in more than one joint is the most common clinical signs. This brings us to CAE (Caprine Arthritis Encephalitis), a nervous disease in goats, first reported in 1974. For general information on managing animal health in Australia (including goats), please consult the latest edition of ‘Animal Health in Australia‘. A buck with CAE can also transmit the virus to a doe during breeding. CAE is a disease of goats caused by a lentivirus.
Any opinions, findings, conclusions, or recommendations expressed in this publication are those of the author(s) and do not necessarily reflect the view of the U.S. Department of Agriculture. 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.
If a goat is diagnosed with CAE and the disease progresses to the point where they are no longer productive members of the herd and are not fit to ship, humane on-farm euthanasia is recommended to minimize suffering.CAE can be spread through contact with milk, saliva, or mucous of infected animals, via coughing, and possibly via other routes if infected and healthy goats are mingled. Also known as paratuberculosis, this infection is contagious, which means it can spread in your herd.
