Lyophilized bovine viral diarrhea vinis (BVDV) vaccines wexe Prepaxal using four xexx,mmendei stabilizing irMiums., 10% NZ-Arnine， 1% Albumin，2% Peptone and 0.3% PVP (Poly vinyl Pyrrolidone). These four vaccines were comparel with each other relative to their suitability for (1). Appearance and solubihty characteristics; (2).maintaining virus tiers during lyophuliazation; (3). cpiality of restoration; (4). maintaining stable of virus titers and antigenicity under varius storage tnreasnes.
From the result, it may ke pttsible to ptpare a more saffsfactry vaccine with a medium juepaxal from comxnent of 0.3% PVP. This may ke worthy of investigation at a later date.
