Total and differential leucocyte counts have been determined by electronic counting techniques in 474, two-to-four-year-old healthy Thoroughbreds in training. The ranges of values observed (particular those for neutrophils and lymphocytes) were narrower than previously described. Absolute and percentage lymphocyte values were significantly decreased with advancing age causing a relative increase in percentage neutrophils. The fall in absolute lymphocyte numbers was the main cause for a significant decrease in total leucocytes with age. Frequency plots for each variable showed that, with the exception of the eosinophil count, data from other leucocyte cell types following either a normal or lognormal distribution.
通过电子计数技术测定了474匹年龄在2至4岁、处于训练中的健康纯种马的白细胞总数和分类计数。观察到的数值范围（尤其是中性粒细胞和淋巴细胞的数值范围）比之前描述的更窄。随着年龄增长，淋巴细胞的绝对值和百分比显著下降，导致中性粒细胞百分比相对增加。淋巴细胞绝对数量的下降是白细胞总数随年龄显著减少的主要原因。每个变量的频率图显示，除嗜酸性粒细胞计数外，其他白细胞类型的数据呈正态分布或对数正态分布。
