The purpose of the study was to elaborate a molecular procedure to identify the DUMPS mutation which causes hereditary disorder (deficiency of uridine monophosphate synthase) in cattle. The degree of this disorder was determined in a gene pool of a Polish bredcattle population which consisted of 1038 animals: 781 artifical insemination bulls from all centers in Poland and 257 sire dams from the two largest breeding centers of Holstein-Friesian cattle: Osięciny and Osowa Sień. The diagnosis was performed using the PCR-RFLP method and technique based on automated solid-phase sequencing of PCR products. In the examined material no DUMPS carrier was found. This indicates that the population of cattle reared in Poland is free from this economically significant disorder. The results obtained indicate a high effectiveness of monitoring of point mutation DUMPS by the PCR-RFLP method. Moreover, it is worth noting the wide possibilities of examining other biologically significant genome regions using the solid-phase sequencing method.
