Donor Herd

Plasvacc USA's equine blood products are collected from a USDA-approved herd of approximately 90 blood donor horses. Prior to acceptance into the closed herd, the Department of Serology, UC Davis screens the animals for their suitability as plasma and red cell donors.

Plasvacc USA's donor herd is routinely vaccinated with the following herd health vaccines: Corynebacterium Pseudtuberculosis, Eastern and Western Encephalomyelitis, Equine Influenza, Equine Rhinopneumonitis, Equine Rotavirus, Rabies, Streptococcus Equi, Tetanus, and West Nile Virus.

Plasma donors must be free of agglutinins and hemolysins to common red cell antigens. Each donor must also test negative for antibodies to EIA, EVA, glanders, dourine, piroplasmosis and brucellosis. Donors are also screened for the presence of TDAV, the Non-Primate Hepacivirus (Equine Hepacivirus [EHCV]), Equine Parvovirus, and Equine Pegivirus (EPgV).

Once accepted into the herd, frequent monitoring ensures continued freedom from disease.
