Abstract
The results of operating a voluntary ovine brucellosis accreditation programme in 14 stud and 9 commercial flocks in the Manawatu district is reported. From a total of 1992 CF test results there were 47 positive and 14 suspicious reactions; a total of 61 reactions (3.06%). Fifty six of these occurred in rams vaccinated during the previous 12 months, and only one further ram with epididymitis had a suspicious, and then a positive, CF test and is assumed to have had brucellosis (0.05%). One of the remaining three suspicious reactions was confirmed as a false suspicious, and the other two remain unclassified as either true or false. It was concluded the CF test is both highly sensitive and specific, and that the official acceptance of accreditation schemes is an urgent priority for the sheep industry.
