[Normal values for the hemoglobin content, hematocrit and the average corpuscular hemoglobin concentration in calves...

Raised calves were analysed for their frequency distributions of haemoglobin, haematocrit, and mean corpuscular haemoglobin concentration, depending on phases of keeping, in two cross-section (n = 146 and 196) and one longitudinal section studies (the latter on three dates, n = 149, 144, and 141). Race, birth weight, age, and live weight of the calves and their fathers as well as lactation age of their mothers were used for reference. All animal groups exhibited at any time of testing significant deviations from Gauss' distribution in all tests undertaken to verify the normality of frequency distributions of the above haematological variables. Those frequency distributions exhibited clearly visible variations, depending on phases of keeping. A concept to meet such conditions is proposed for evaluation of all variables of the red blood count.
