INFLUENCE OF TAQI POLYMORPHISM IN MELANOCORTIN RECEPTOR (MC4R) ON PIG SLAUGHTERING TRAITS

Cilj ovog istraživanja bilo je utvrditi kako polimorfizam MC4R gena utječe na klaonička svojstva. Ispitivanje je provedeno na 60 križanaca pasmina veliki jorkšir i njemački landras na strani majke i duroka na strani oca. Prema ispitivanjima utvrđeno je da polimorfizam MC4R gena utječe na pojedina kvantitativna svojstva svinja vezana uz unos hrane kao što su debljina MLD-a. električna provodljivost i boja mišićnoga tkiva. Predočeni rezultati ispitivanih klaoničkih svojstava ukazuju na potrebu daljnjih ispitivanja, kako bismo dobili objektivniju povezanost polimorfizma MC4R gena s klaoničkim svojstvima. Također je potrebno povećati broj ispitivanih jedinki, jer je broj od 60 svinja relativno malen. Osim broja jedinki, potrebno je proširiti ispitivanje na druge pasmine svinja, kako bismo otkrili povezanost polimorfizma MC4R gena s klaoničkim svojstvima unutar pojedine pasmine, jer je do sada utvrđeno da polimorfizam MC4R gena djeluje na klaonička svojstva različito, ovisno o ispitivanoj pasmini.The aim of the research was to determine the influence of polymorphism in MC4R genes on slaughtering traits. The research was carried out on 60 crossbreeds of Large White and German Landrace in the dam line and of Duroc in the sire line. According to tests performed, it was determined that polymorphism in MC4R genes affected some quantitative traits of pigs related to feed intake, like MLD thickness, electric conductivity and meat color. Presented results of the examined slaughtering traits pointed out the need for further research in order to obtain more realistic relation of polymorphism in MC4R genes and slaughtering traits. It is also important to increase the number of pigs under research, as 60 pigs are a relatively small number for such research. Furthermore, other pig breeds should be involved in the research aiming to examine connection of polymorphism in MC4R genes with slaughtering traits within one particular breed, especially if it is known that polymorphism in MC4R genes affects slaughtering traits in different ways, depending on the examined breed
