The PPARD gene is involved in mechanisms related to energy metabolism, fat utilisation and muscular endurance. In racing pigeons, a recent study suggests that certain variations in this gene may be linked to race performance, particularly return speed and ranking coefficient. The CC genotype for the PPARD c.*271C>T marker is the one that stands out most favourably in the study, notably because it was observed in pigeons taking part in a larger number of races. This test can therefore provide complementary information to guide the selection of breeding birds, without replacing the assessment of the pigeon, its lineage, training and actual racing results.
