![]() ![]() A program of eradication is discussed in which kids are removed from their dams at birth, fed safe sources of colostrum and milk, and isolated from other goats until weaning. Heat inactivation (56 C) reduced approximately 10(5) median tissue culture infective doses of caprine arthritis-encephalitis virus to below titratable levels, and virus was not transmitted to kids fed virus-infected colostrum that had been heated at 56 C for 1 hour. Caprine arthritis-encephalitis virus (CAE) is a single-stranded, icosahedral, RNA virus of the family Retroviridae and the sub-family Lentivirinae. There is no known treatment for CAE, so prevention is the best way to minimize the impact of this disease on your farm. ![]() However, when uninfected does were milked with infected does, a high percentage became infected in less than 10 months. Prolonged direct contact for over 12 months between weaned cesarean-derived goats and virus-infected goats was necessary before horizontal transmission could be demonstrated under nondairy conditions. Transmission by the aerosol route was not demonstrated, and even short-term direct contact between virus-infected bucks and virus-free does during breeding did not result in transmission. Intrauterine infection may have occurred in 2 of 32 cesarean-derived goats, but postpartum horizontal transmission could not be ruled out. Basically, this virus is responsible for. ![]() In addition, it appeared that transmissions through other secretions of the doe occurred, but were less important than transmission in milk and colostrum. Caprine arthritis-encephalitis (CAE) is one of the major diseases, among the other disease affecting the goat industry. Caprine arthritis-encephalitis virus was isolated from goat milk and transmitted most efficiently to kids through both milk and colostrum. ![]()
