Evaluation of Czech Warm?Blood Stallions Based on Performance of Their Daughters

摘要

The objective of the present study was to assess the Czech warm?blood stallions based on results of basic performance tests of their daughters. We evaluated 1140 daughters of 51 fathers. On the basis of calculations we eliminated the following effects: year of the test, registration of the mare in the appropriate section of the Stud Book and group of commissioners. Data were evaluated using the GLM procedure and included the effect of the stallion, year of the performance test of the mares and filing in the respective section of the Stud Book. We discovered that the impact of all three effects was statistically significant. The effect of the stallion was just below the margin of significance P ≤ 0.05, the other two effects were below P ≤ 0.01. We compared the stallions – fathers, according to the average performances of their daughters in the basic performance tests. The performances of daughters of stallions 1850 Cannavaro, 2901 Lancelot, 1659 Jimtown, 1028 Manillon Rouge and 1053 Guidam Sohn were the highest; the performances of daughters of stallions 1260 Askano?T, 718 Mineral 1599 Norman, 2726 Cartouche and 1358 Lord Caletto were the lowest.
