The objective of this study was to estimate genetic trends in the Polish Arab horses population. Annual earnings and rank at finish in the Polish Arab horses from 1951 to 1993 were analysed with a BLUP animal model. The collected data included 2,234 records of 1,640 4- and 5-year old horses from 143 sires. Only races, in which horses of least two mentioned age groups took part, were taken into consideration. The model included an individual additive genetic effect as random, the year of race, herd, sex, age, number of starts and the year of race X age effect as fixed effects
