Abstract. The aim of the present study was to analyze and compare the inbreeding level of the Holstein stallions presented for classification for breeding in 2003–2012 in Germany. The data were collected from the Holsteiner Korung und Reitepferde – Auktion catalogues. Based on the analysis of 869 pedigrees (up to the fifth generation inclusive), inbreeding coefficients (F), expressed as a percentage for each stallion, were calculated. The highest F values were recorded in 2003 (2.05%) and 2004 (1.74%). Statistically significant differences in the F values of the stallions from individual years were found. The outcomes of the present study show that the breeding work based on conscious assumptions is carried out in order to increase an inbreeding level in the sport horses’ production, regarding at the same time that the value of the inbreeding coefficient cannot be too high.
