Dependence on live weight and age]. PG - 801-16 AB - The hamoglobin content (Hb), the hematocrit (Hc) resp. the mean corpuscular hemoglobin concentration (MCHC) were determined resp. calculated of the blood samples (1 to 6 per animal) taken from 491 rearing calves during the first 23 weeks of their lives. Hb, Hc and MCHC were graphed as arithmetic means with standard deviation, as quartiles and as frequency distributions on an interval scale in dependence on live weight (20 ... 160 kg) resp. age (1 ... 161 days). It follows that the period of development from birth up to 28 days of keeping in the weaning area of the rearing farm, up to an age of 63 days resp. a live weight of 80 kg must, under the reference conditions, be considered the minimal period in which the supply of iron covering the needs by iron intervention in the whole stock of calves seems advisable.
