Summary Clinical conditions affecting the reproductive organs were found affecting 17.2% of 2,332 rams. The following conditions were found: epididytimis 69.4%, atrophy 15.4%, varicocoele 9.5%, hernia 2.9%, cryptorchidism 1.2%, and hydrocoele 1.5%. The incidence of Brucella ovis antibodies as determined by the CF test in 2,332 rams from 12 flocks in north western Queensland was found to be 18.3%. The age distribution of ovine brucellosis among 1,772 rams whose ages were known was as follows: 1 year 2.1%, 2 years 10.4%, 3 years 15.9%, 4–7 years 21.8%, and over 7 years 24.4%. The age incidence of all the various clinical conditions as they affected the 1,772 rams was: 1 year 3.6%, 2 years 8.4%, 3 years 13.1%, 4–7 years 28.4%, and over 7 years 27.9%. Control of brucellosis in two flocks is reported and a possible means of control of this disease in Queensland is discussed.
