Problems Encountered In The Control Of Heartwater In Angora Goats
This preliminary investigation confirmed that when Angora goats were immunized against heartwater, either when kids or young goats, they still had an immunity to heartwater a year later when they were challenged with a vaccine containing Cowdria ruminantium. An overwhelming majority of the uninoculated animals which were challenged at the same time were susceptible to clinical heartwater. Strategic immunization to obtain enzootic stability to heartwater is suggested. In these experiments the immunization of Angora goats was not accompanied by severe losses.
