In this study, blood serum was collected from 162 repeat breeder (RB) dairy cows and tested by enzyme linked immunosorbent assay (ELISA). Of these samples, 87 were bovine herpesvirus type-4 (BHV-4) seropositive and 75 were BHV-4 seronegative. The prevalence of BHV-4 was determined as 53.70% amongst RB dairy cows. In the current study the seroprevalence was high. The average days open (DO) of pregnant BHV-4 seropositive RB cows was significantly longer (p<0.01) than that of pregnant BHV-4 seronegative RB cows, but was not significant for age of animals (p=0.186) or conception rate (CR) (p=0.14). The averages calving to the fourth insemination date (CFIDI) and age of nonpregnant BHV-4 seropositive RB cows was significantly higher (p< 0.05) than non-pregnant BHV-4 seronegative RB cows. In conclusion, a close fertility negative relationship existed between BHV-4 infections and fertility in RB dairy cows.
