The goal of this work was to work up the survey about usage and fertility of stallions using in Czech warmblood breeding. All data originate from breeding evidence of Czech warmblood Breeders Association, Association of Horse Breeder´s Unions of the Czech Republic and Czech Equestrian Federation (years 2002 {--} 2008). It has been evaluated frequency of stallion using in each period, the numbers of fertilized mares and the numbers of foals borning after each stallions. Frequency of using the stallions was compared with achieved level their sports performance. The results of the numbers of borning foals in each years were in interval 917 {--} 1360 and gradually falls. In average 6 foals were born to one stallion. Natality was in interval 32,3 % - 74,4 %, 11 fertilized mares to one stallion in average. From 13 to 21 % stallions used in breeding have no offspring. It was made out that the using of stallions with hight performance grow up from 11,4% to 21,1 % by sports performance T and from 3 % to 7,1 % by sports performance TT. Detected rates from the analysis of stallions usage in breeding Leeds to conclusion, that the number of present stallions should be lower, but the frequency of usage should be higher.
