Sixteen cattle with ages ranging from 1 to 15 months, males and females, affected by umbilical diseases were enrolled in the study. Blood samples were collected for cell counts and the determination of immunoglobulin concentrations by electrophoresis and zinc sulphate turbidimetry (ZST). Four calves were presented with umbilical herniation, two with an umbilical herniation associated with a persistent urachus, two with an umbilical herniation with a persistent urachus and omphaloarteritis, three with an umbilical herniation and an urachal diverticulum, three with a persistent urachus, one with an urachal diverticulum, and one with omphalitis. The blood cell counts pre- and post-surgical revealed differences in cell volume and the number of leukocytes. The immunoglobulin values measured by electrophoresis values were below normal in most animals, whereas the ZST showed normal levels in most of them. Most of the calves affected by umbilical diseases and produced by IVF presented hypoglobulinaemia. Correlations between umbilical diseases, failure of passive transfer of immunity and IVF could not be demonstrated.  aCalves  aIn vitro fertilization  aBezerro  aClínica  aClinics  aFailure of passive transfer of immunity  aFalha de transferência de imunidade  aFertilização in vitro  aOmphalitis  aOnfalite  aPersistent urachus  aÚraco patente1 aSANTOS, P.
