From 203 male rearing calves in a longitudinal study during the first rearing period in a rearing farm the time could be determined in which the hemoglobin quota, the hematocrit resp. the average corpuscular hemoglobin concentration were lower than 10,5 g/dl, 33% resp. 30.5 g Hb/dl erythrocytes. The average duration of anaemia was 45, 29.5 resp. 44 days of the total of 56 keeping days in this rearing range (80.4%, 52.7% resp. 78.6% of the keeping period). During this rearing period 89.2%, 71.4% resp. 90.6% of all animals were anaemic for a shorter or longer time. With 29.8%, 26.2% resp. 29.9% of the anaemic calves the anaemic phase exceeded 56 days.
在一个饲养场对203头雄性育肥牛犊进行的第一个饲养期纵向研究中，能够确定血红蛋白含量、血细胞比容以及平均红细胞血红蛋白浓度低于10.5克/分升、33%以及30.5克血红蛋白/分升红细胞的时间。在这个饲养阶段的56天饲养期内，贫血的平均持续时间分别为45天、29.5天以及44天（分别占饲养期的80.4%、52.7%以及78.6%）。在这个饲养期内，分别有89.2%、71.4%以及90.6%的所有动物出现了不同时长的贫血。分别有29.8%、26.2%以及29.9%的贫血牛犊贫血期超过了56天。
