| Abstract: | Three commercial flocks, deriving replacement rams from 15 parent studs, had respectively 33 of 71,13 of 31 and 8 of 82 rams positive to the Br. ovis CF test. In the first flock, clinical findings supported a diagnosis of active Brucella infection. In the other two flocks, positive results were attributed to vaccinational titres persisting for up to 3 years after vaccination. It is concluded that permanent identification of vaccinated rams would assist in Br. ovis flock-testing programmes. |
