The blood values of the German Brown, N'Dama and their three-quarter, half and quarter hybrids were studied to ascertain if and how some haematological parameters changed with crossbreeding. It was found that the red blood cell (RBC) and white blood cell (WBC) count and packed cell volume percentage (PCV) were significantly higher (P less than 0.01) in the N'Dama than in the German Brown; the crosses had values which were intermediate as compared to the two parent breeds. Generally, the changes in the mean blood values paralleled changes in the expected genotypes resulting from crossbreeding of the two parent breeds. The tendency of the blood values to change in direct proportion to the degree of N'Dama contribution was strongest for the WBC, followed by the PCV and RBC, respectively. A small random sample for leucocyte differential count did not reveal any differences amongst the genotypic groups.
对德国黄牛、恩达玛牛及其四分之三、二分之一和四分之一杂交后代的血液值进行了研究，以确定某些血液学参数是否以及如何随杂交而变化。结果发现，恩达玛牛的红细胞（RBC）和白细胞（WBC）计数以及血细胞比容百分比（PCV）显著高于（P小于0.01）德国黄牛；与两个亲本品种相比，杂交后代的值处于中间水平。一般来说，平均血液值的变化与两个亲本品种杂交产生的预期基因型变化平行。白细胞计数的血液值随恩达玛牛贡献程度直接成比例变化的趋势最强，其次分别是血细胞比容和红细胞计数。一小份用于白细胞分类计数的随机样本未显示基因型组之间存在任何差异。
