An attempt at objectivization of the halfbred stallion's performance test in Poland. II. 100-day test.

摘要

The aim of this study was to investigate the usefulness of results and possibility of objectivization of stallion's 100-day performance tests. No correlation between performance test results and number of covered mares was found. An objectivization attempt was made on the basis of physiological blood analyses after the stamina trial (5 min gallop) and on the basis of some measurements of free jumping parameters by means of video image analysis (VIA). Additionally, an analysis of the relations between different performance test trials was made. The correlations between evaluation of jumping traits in the performance test were at medium level and were from 0.47 to 0.73. The correlations between results of jumping skills from the test and measurements from VIA were weak and ranged from -0.1 to 0.3. Results of blood analyses reached values within a normal range. Only heart rate values seemed to be too high relative to the effort of this test. This provides some possibility to improve the objectivity of the performance test for young stallions.
