The aim of the study was to evaluate the basic motion indicators of half-bred stallions subject to the performance test in the Training Center as well as to analyze the correlation between these indicators and the performance test scores. A group 236 half-bred stallions (219 horses) and foreign breeds (17 horses) were tested. Results from the performance test of the stallions were evaluated. In addition, the length of five strides and duration of these strides was measured. Based on the results, the following items were calculatedfor each stallion: length of a single stride, fre-quency of strides per minute, and walking and trott ing speeds. A significant effect of the stallions breed on the results of their assessment in the performance test, was recorded. The highest scores for the vast majority of traits occurred in foreign breeds, and the lowest in Malopolski breed stal- lions. Evaluation of the stallions’ motion indicators was partly correlated with results of the as-sessment made in the Training Center. The largest number of correlations occurred between the scores awarded for stallions for work during walk, trot, and gallop and the length and frequency of stride in trot as well as the length of stride in walk.
