SUMMARY An investigation was conducted to determine if depriving goat kids of colostrum and rearing them away from the herd would prevent transmission of caprine retrovirus infection. Twenty‐four newborn goat kids were deprived of colostrum and reared on cow's milk away from their dams from an endemically infected goat herd. Twenty‐three colostrum‐deprived kids had no evidence of retrovirus infection at birth. One kid had sucked briefly and obained some colostrum resulting in passive transfer of antibody but it did not develop evidence of infection. Nineteen showed no serological evidence of infection over the 370 days of the study. One colostrum‐deprived, segregated goat was subsequently found to be infected and developed arthritis‐synovitis. Three had doubtful positive response in one or 2 serological tests during the period but no evidence of infection in leucocyte co‐cultures. Cells centrifuged from colostrum of infected goats were co‐cultivated with foetal goat synovial membrane cultures. Caprine retrovirus was isolated from cells in the colostrum from the 3 goats examined.
