Investigated were the usefulness and possible objectivization of the results of stallions’ 8-months performance test. No correlation was found between the total results of the test and the number of mares covered by tested stallions, suggesting that the use of stallions does not depend on the result of their 8-month test. Blood samples were analysed after the stamina trial (cross country gallop) and some parametres of free jumping were measured based on video image analyses. Moreover, an analysis of relations was done between performance test trials and investigated parametres. The correlations between evaluations of jumping traits in the performance test ranged from 0.28 to 0.65, while those between the results of jumping skills from the test and measurements based on video image analysis were weak and ranged from -0.2 to 0.3. Blood physiological indicators showed a wide range of values. Lactic acid content was affected by individual riders and breeders and that of total protein by breeders only.
