Abstract |
The effect of bovine viral diarrhoea virus (BVDV) infection on early pregnant cows between 10 and 24 days after virus inoculation at day 26 of pregnancy was determined. Four cows were inoculated intravenously with either BVDV (treated, n=3) or growth medium (control, n=1). The treated cows were euthanized on either day 10, 17 or 24 post- infection and the control cow was euthanized on day 24 post- infection. The level of serum 2-5A synthetase increased in all of the three treated cows. Progesterone levels decreased to below 1.0 ng/ml between 10 and 22 days after inoculation in two of the three treated cows and the embryos/foetuses of two cows died. Therefore, BVDV may be a cause of early embryonic or feotal loss in early pregnant cows and serum 2-5A synthetase may be useful as an indicator of viral infection in cows.
