Failure to conceive and repeat breeding is generally the only symptom seen. Instead, repeat breeding appears to occur after the virus settles in the ovary, from the bloodstream, resulting in failure of conception. Affected animals eventually return to heat and are fertile. It is important producers realize symptoms of IPVV are not necessarily associated with infertility due to bovine herpesvirus 1. There is no known treatment for bovine herpesvirus 1.
Vaccination is the best method of control.
Many killed and modified live virus vaccines are available. The choice of product and the time to use it varies with each management situation. A vaccine should be chosen in consultation with a veterinarian because the wrong choice can lead to abortion of pregnant cows in a herd. Effects of the virus include mucosal disease, bovine virus diarrhea, abortion and birth defects in newborn calves. More recently the virus has also been associated with repeat breeding in cattle herds.
