Abstract

Infectious bovine rhinotracheitis caused by bovine herpesvirus 1 (BoHV-1), which negatively affects the production performance of infected cattle herds, results in considerable economic losses in dairy farms. The present study aimed to estimate farm-level production and reproductive performance losses in seropositive (SP) dairy cattle infected with BoHV-1. A total of 266 non-vaccinated cows were selected from 31 herds located in different parts of Hatay, Turkey. Data collected from SP and seronegative (SN) cows were compared with each other. Compared to the SN cows, 10% and 9% decreases were found regarding milk production (P<.01) and live weight (P<.01) in SP cows, respectively. Reproductive and mixed clinical problems in infected cows lead to the highest losses in respect of milk production and live weight, respectively. The financial loss due to the infection was estimated to be $US331 if abortion does not occur, and $US509 if abortion occurs as a result of the infection. Considering the likelihood of abortion, the average cost of infection was estimated to be $US379 per infected cow.
