The haemoglobin and haematocrit levels were studied in three groups of about thirty male Dutch-Friesian veal calves. The iron content of the milk replaces was 5, 10 and 25 ppm. During the experiment which was continued for sixteen weeks, the haemoglobin and haematocrit levels decreased in all groups. The decrease was confined to the first six weeks in the calves fed the milk replacer containing 25 ppm of iron. In the two other groups, the decrease of the two criteria continued throuhgout period. Regardless of the iron content of the milk replacer, the decrease of Hb- and haematocrit levels of the individual calves was greater in those having the highest initial level. The borderline for anaemia in a group of sixteen-week-old veal calves is estimated at approximately 10 g. Hb/100 ml. blood. For an individual calf, the borderline is estimated at 8 g. Hb/100 ml. blood.
对三组约30头雄性荷兰弗里西亚犊牛的血红蛋白和血细胞比容水平进行了研究。代乳品的铁含量分别为5 ppm、10 ppm和25 ppm。在持续16周的实验期间，所有组的血红蛋白和血细胞比容水平均下降。在饲喂铁含量为25 ppm代乳品的犊牛中，这种下降仅限于前六周。在另外两组中，这两个指标的下降在整个实验期间持续存在。无论代乳品的铁含量如何，初始水平最高的个体犊牛的血红蛋白和血细胞比容水平下降幅度更大。一组16周龄犊牛的贫血临界值估计约为10 g Hb/100 ml血液。对于个体犊牛，临界值估计为8 g Hb/100 ml血液。
