[Anemia of male rearing calves. Connections between anemia and feed consumption, development of the live weight and disease development].

Calves in a longitudinal investigation over the first rearing period in a rearing farm were grouped according to their anaemic status under consideration of the degree of severity and the duration on the basis of the hemoglobin contents resp. the hematocrit values on the 3rd, 28th and 56th rearing day. There were significant differences between the groups of calves with differing anaemia status concerning the absolute and relative feed consumption (milk, concentrated feed, hay resp. iron), the development of the live weight as well as the frequency of the treatment against pneumonia and/or diarrhoea.
