    In the Kruger National Park 75% of zebra foals are born in October-March and they lose their passive immunity against African horsesickness virus (AHSV) when they are 5-6 months old. One month later infection with different ...
  • Current status of fox rabies in Europe

    There was a general decline in animal rabies in Europe in 1991 following the peak levels which occurred in 1989. This was ascribed, in France at least, to the normal decline in cases usually experienced following peak ...
  • Cyclic fluctuations in acetone concentrations in the blood and milk of clinically healthy dairy cows 
    Winterbach, Hanlie Evelyn Kathleen; Petzer, Inge-Marie; Apps, P.J.; Giesecke, W.H.; Verwoerd, Daniel Wynand (Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1993)

    Perry, B.D. (Brian D.), 1946-; Verwoerd, Daniel Wynand (Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1993)
    With an apparent decline in rabies vaccination coverage in dog populations in many parts of eastern and southern Africa, consideration should be given to more effective targeting of rabies vaccination to protect those ...
