Influence of indirect factors and its effect analysis on performance level of Slovak warmblood horse breed

During their career, horses are affected by a large number of direct and indirect factors. The aim of our study was to determine the effect of indirect factors, such as year of start, sex, breed, number of starts, age and proportion of genes of Slovak Warmblood horse breed. For determination of indirect factors on performance level, results from test efficiency and final placement in showjumping category 4, 5 and 6 years old young horses were used. 540 horses of Slovak Warmblood breed were analysed between 2015 - 2019 and 1155 data samples were collected. Based on the results of the linear model, parameters – the effect of gender and the influence of the gene proportion of Slovak Warmblood horse had statistically significant influence (p<0.05). High significant effect (p<0.001) on performance of Slovak Warmblood horse was observed in parameters – year of start, age during start and breed.
