Clinical immunological and haematological parameters, along with clinical conditions and growth rate, were studied in 413 male Holstein Frisian calves introduced into a large centre for genetic selection in different seasons of the year. Abnormalities were revealed by the laboratory tests in the great majority of calves after transportation stress, a general tendency to the restoration of physiological values being evident thereafter. Laboratory parameters were highly correlated with disease conditions: with three exceptions only, animals showed altered laboratory parameters some days before the occurrence of clinical symptoms. Eighteen per cent of animals showed altered laboratory parameters with no obvious clinical signs of disease; yet they experienced a reduced weight gain. Results suggest that clinical immunological and haematological parameters could be the foundation of a new, large-scale, robust approach to the control of welfare in cattle, which should be integrated preferably by a further range of records and measures.
对413头引入大型基因选择中心的雄性荷斯坦弗里生犊牛在一年不同季节的临床免疫学和血液学参数，以及临床状况和生长率进行了研究。在运输应激后，绝大多数犊牛的实验室检测发现了异常，此后生理值恢复的总体趋势明显。实验室参数与疾病状况高度相关：仅三个例外，动物在出现临床症状前几天实验室参数就发生了改变。18%的动物实验室参数发生改变，但无明显疾病临床体征；然而它们的体重增加减少。结果表明，临床免疫学和血液学参数可能是一种新的、大规模、稳健的牛福利控制方法的基础，最好通过一系列进一步的记录和措施加以整合。
