Abstract

A number of infectious agents are potential threats to the fetus of a pregnant cow with resultant abortion. These agents include Leptospira sp., Campylobacter fetus and agents such as infectious bovine rhinotracheitis (IBR) and bovine virus diarrhea (BVD) viruses. Maintenance in the cow of a high level of immunity to these agents during pregnancy can insure protection of the fetus. In particular, vaccines against BVD and IBR viruses can establish protective immunity throughout gestation.
