Vibriosis/Campylobacteriosis Cattle • Venereal disease (mating or AI) • Bulls – bacteria present in prepuce, penis and semen • Cows – Reproductive tract Sheep • Spread by ingestion of contaminated water or feed (placental/aborted material, faeces)
Clinical signs Cattle: • No obvious signs in bulls • In cows – abortion and infertility • Cows returning to oestrus • Low conception and/or calving rates Sheep: • Abortions • Extended breeding season. • Low lambing rates • Poor milk supply • Weak and dying lambs
Prevention * Vaccinate bulls (and cows) annually (2 shot initial course) * Vaccination should be given 4 weeks before joining. * Use CHS to demonstrate pre-purchase vaccinations in bulls * Culling older bulls Vaccination regimes: 1. Do not vaccinate 2. Vaccinate all bulls 3. Vaccinate all heifers 4. Vaccinate all bulls and heifers 5. Vaccinate all bulls, heifers and cows.
