20.500.12556/RUL-186168 Analiza sorodstva in inbridinga na podlagi rodovnikov v populaciji arabskih polnokrvnih konj v Sloveniji diplomsko delo Relationship and inbreeding analysis based on pedigree in the population of purebred Arabian horse in Slovenia B. Sc. thesis Reja in vzreja arabskih polnokrvnih (AP) konj se je v Sloveniji začela v poznih 80. letih 20. stoletja, ko so bili uvoženi prvi plemenski žrebci in kobile iz tujine. Namen diplomske naloge je bil opisati populacijo AP konj v Sloveniji ter oceniti njeno strukturo, sorodstveno povezanost in raven inbridinga. Analizirali smo podatke o poreklu in državi rojstva živali iz rodovniške knjige v Centralnem registru kopitarjev (CRK). Po preverjanju in uskladitvi rodovnika je bilo v analizo sorodstva in inbridinga vključenih 3378 živali. Za statistično analizo podatkov smo uporabili statistični program R. Stalež AP konja se v zadnjih dveh desetletjih v Sloveniji povečuje, prav tako se povečuje število plemenskih živali in v Sloveniji rojenih žrebet, kar kaže na krepitev domače populacije. Analiza izvora živali je pokazala heterogeno poreklo današnje populacije, pri čemer so imeli največji vpliv konji iz Združenih držav Amerike in Poljske, rojeni med letoma 1970 in 1990. Povprečno največje število sledljivih generacij je znašalo 4,18, povprečno ekvivalentno število popolnih generacij 2,57, povprečni indeks popolnosti rodovnika pa 49,3 %. Povprečni koeficient inbridinga (F) je znašal 1,28 %, pri čemer je bilo inbridiranih 32,8 % živali. S povečevanjem popolnosti rodovnika sta se povečevala tako koeficient inbridinga kot delež inbridiranih živali, kar nakazuje, da je dejanska raven inbridinga v populaciji verjetno podcenjena. Breeding of Arabian Purebred (AP) Horses in Slovenia began in the late 1980s, when the first breeding stallions and mares were imported from abroad. The aim of this thesis was to describe the AP horse population in Slovenia and to assess its population structure, relatedness, and level of inbreeding. We analysed pedigree data and country of origin, that we obtained from stud book in Central register of Equidae. After verification and harmonization of pedigree records, 3378 animals were included in the analyses of relatedness and inbreeding. Data analyses were performed using the R statistical software. The AP horse population in Slovenia has increased over the last two decades, accompanied by an increasing number of breeding animals and foals born in Slovenia, indicating that the national population is strengthening. Analysis of animal origin revealed a heterogeneous population structure, with the highest influence originating from horses born in the United States of America and Poland between 1970 and 1990. The average maximum number of traced generations was 4.18, the average equivalent of complete generations was 2.57, and the average pedigree completeness index was 49.3%. The average inbreeding coefficient (F) was 1.28%, with 32.8% of animals being inbred. Both the inbreeding coefficient and the proportion of inbred animals increased with pedigree completeness, suggesting that the actual level of inbreeding in the population is likely underestimated. konji pasme arabski polnokrvni konj sorodstvo inbriding populacije Slovenija diplomska dela horses breeds purebred Arabian horse relationship inbreeding populations Slovenia true false false A.
