Good Practice based on Current Knowledge

To prevent abortions from happening or abortive agents from entering the herd:

• Establish a closed herd policy.
• Screen and isolate bought-in animals.
• Establish good biosecurity on the farm.
• Establish a good recording system for abortions on the farm (date, cow, stage of gestation, additional information, results of systemic examination by a vet).
• Get a veterinarian to carry out a systemic examination of all cases of abortion in the herd if the annual incidence is more than 4% (4 cows in 100).
