Blood was obtained from 61 neonatal Holstein calves originating from a farm in Germany with a high incidence of bovine neonatal pancytopenia (BNP). In order to detect alterations that might be related to BNP, selected haematological analytes were determined. Haematological examinations demonstrated alterations in at least two of the three cell lineages in 10 calves (16.39 per cent). Six animals (9.84 per cent) developed a bleeding disorder indicative of BNP at approximately two weeks of age. None of these animals showed alterations in complete blood cell count at sampling in the first week of life. In weeks when calves with BNP were born, an increase in the number of apparently healthy calves demonstrating decreases in blood cell counts was observed.
从德国一家高发性牛新生全血细胞减少症（BNP）的农场获得了 61 头荷斯坦小牛的血液。为了检测可能与 BNP 相关的变化，选择了一些血液分析物进行测定。血液学检查显示，在 10 头小牛（16.39%）中，至少有两个细胞谱系发生了改变。6 头动物（9.84%）在大约两周龄时出现了表明 BNP 的出血性疾病。这些动物在生命的第一周采样时，没有任何全血细胞计数的变化。在有 BNP 的小牛出生的几周内，观察到数量增加的表现出血液细胞计数减少的看似健康的小牛。
