Abstract. The LDHA/HaeIII polymorphism (g.2582481G>A) in pigeons is associated with physiological predispositions for rapid return and endurance, which are one of the most desired racing performance traits. Thus, the aim of the study was to analyse the association between the g.2582481G>A polymorphism with the relative expression level of LDHA in the group of young homing pigeons. The results demonstrated differences, but not significant in the relative LDHA expression level in the group of pigeons carrying different LDHA genotype. The highest expression of LDHA gene in pigeons carrying LDHAAG genotype was reported. Moreover, the differences in the average relative quantity of the LDHA gene were different in relation to gender, with a slightly higher expression level of the LDHA gene in females. In conclusion, the highest expression level of LDHA gene in homing pigeons with genotype AG may explain the better racing performance of LDHAAG pigeons reported in previous studies.
