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
