Abstract
Ram epidiymitis caused by Brucella ovis can be effectively controlled by an annual program combining rigorous culling of clinically affected animals and appropriate vaccination of the remaining animals. Yearling rams purchased or saved as replacement breeders should be immunized at 4-5 mo. of age by 2 injections of B. ovis bacterin spaced 3-6 wk apart. Annually, approximately 1 mo. prior to the breeding season, all rams, replacements and older breeders, should be carefully examined by palpation of the scrotal contents. Every ram evidencing an abnormality should be culled as a breeder. All the remaining rams should receive a booster injection of B. ovis bacterin.
