Abstract

The act of expelling a living or dead fetus from the uterus from 5 weeks to about 40 weeks of pregnancy is called abortion, when it is unable to exert an independent life in an extra-uterine environment. Only 30% to 40% of aborted fetuses have defined etiological diagnosis because of the many causes involved. Among these causes have bovine viral diarrhea and infectious bovine rhinotracheitis. The economic losses caused by these diseases are represented by the decrease in reproduction, infertility of sick animals, the embryonic deaths with repetitions of cycles, the abortions, the births of calves with congenital defects and delayed development.
