Hemorrhagic diathesis in neonatal calves is a new and emerging disease of young calves. The disease affects calves aged less than 4 weeks. Clinical signs in calves include skin and intestinal bleeding as well as petechiae on all mucosal membranes. The cause of this syndrome is as of yet unknown. In this study, to the best of our knowledge, the authors demonstrated the first case of hemorrhagic diathesis in neonatal calves with hematological and histopathological diagnosis. Clinical examinations demonstrated cutaneous bleeding. Hematological examination showed thrombocytopenia (43.7 × 10⁹/L) and pancytopenia (1.47 × 10⁹/L). During necropsy multiple generalized petechiae, ecchymoses or hemorrhages were ascertained. Histopathology revealed a multifocal extravasation of red blood cells (hemorrhage). Severe loss of hematopoietic tissue of the bone marrow was the most prominent finding on histology. The BVD antigen test was negative.
