Evaluating and comparing descendants from the Ladykiller and Cor de la Bryère lines in Czech Warmblood breeding according to basic body measurements

Original language description

The aim of this study was to evaluate the influence of the Ladykiller and Cor de la Bryère lines in Czech Warmblood breeding. Offspring by stud horses authorized to operate in Czech Warmblood breeding were used to evaluate the significance of these breeding lines. The observed attributes for evaluating the quality of the stud horses and lines were the values of the basic body measurements of their offspring (SHW - stick height at withers, THW - tape height at withers, ChC - chest circumference and CBC - cannon bone circumference). The descendants of a total of 24 breeding stallions were compared, of which 14 were Holsteiners, four were Hanoverians, four were Czech Warmbloods and two were Bavarian Warmbloods. The group for comparison consisted of 804 descendants from the Czech Warmblood breed by these sires. An underlying database was created on the basis of information published on the website of the Association of Czech Warmblood Breeders. The data were processed in the statistical programme Unistat 6.5 using a GLM linear model and the results obtained were subjected to multiple testing by the Tukey-B method. The influence of the line, the sire, the year of birth, the sire&apos;s breed and sex on the basic body measurements of descendants were determined and compared. Evaluation by the GLM model revealed a high statistically conclusive influence of the sire on THW, ChC and CBC. The stud horses with the greatest influence on chest circumference were found to be the stallions Landino and Loutanos Orion. Cannon bone circumference is influenced most by the stud horse Caesar. Descendants from the 1994 year group have statistically highly conclusively greater cannon bone circumference, chest circumference and tape height at withers. The influence of the line was demonstrated in only one observed attribute: cannon bone circumference. Here the Cor de la Bryère line achieved statistically highly conclusively greater results than the Ladykiller line.
