Because of the significant time delay between the entry of pigeons for a race and the actual liberation time many performance enhancing drugs illegally used in other contests are rendered ineffectual for pigeon racing. It is, however, policy that pigeon racing remains free of any administered performance enhancing drugs and this has particular reference to the use of any of the anabolic steroids and corticosteroids. Any competitor found to have entered a pigeon treated with any performance enhancing drug will be held responsible and be dealt with by PRNZ. Any pigeons found sick or dead within the race hampers at liberation will be sent for analysis. Where a performance enhancing substance is detected the owner/s will be held responsible and be dealt with by PRNZ.
