For example, demographers use information in the report to calculate pregnancy rates, which are combined estimates of births and fetal loss.

In terms of safety, 22 members of the panel considered it investigative, citing concern over the risk of fetal loss following the procedure.

This data includes live births, abortions, and fetal losses.

Every major breeding farm in central Kentucky has been affected, with several experiencing fetal and foal losses as high as 30 percent.

Overall mortality rate is 20-30%; of all pregnancy-related cases, 22% resulted in fetal loss or neonatal death, but mothers usually survive.
