Abstract
Govedarska proizvodnja teži zadovoljiti potrebe potrošača uzgajanjem i selekcijom pasmina protežirajući one genotipove koji će osigurati kvalitetno meso. Jedan od gena za kojeg se smatra da utječe na ekonomski važna svojstva mesa kao što su mekoća i zamašćenost (mramoriranost) je tiroglobulin (TG). Stoga je cilj rada bio utvrditi postojanje polimorfizma TG gena i njegov utjecaj na kvalitetu trupova i mramoriranost mesa križanaca simentalske i holštajn pasmine goveda. Polimorfizam TG gena utvrđen je u križanaca oba spola te su utvrđena samo dva genotipa (CC i CT), dok genotip TT nije utvrđen. U promatranom uzorku utvrđena je veća zastupljenost alelne varijante C i genotipa CC. Nije utvrđen statistički značajan utjecaj TG gena i spola na odlike kvalitete trupova križanaca simentalske i holštajn pasmine goveda. Interakcija TG gena i spola na odlike kvalitete trupova između muških i ženskih križanaca oba genotipa bila je statistički značajna za pokazatelje tjelesne mase kod klanja i dnevni prirast, mase toplih i hladnih polovica pri čemu su muški križanci ostvarili veće vrijednosti. Interakcija TG gena i spola križanaca na pokazatelje zamašćenosti trupova, klasiranje i mramoriranost nije bila statistički značajna.
Abstract (english)
Beef cattle production strives to meet the consumers’ needs through breeding and selection of genotypes that will ensure meat quality. One of the genes, which affect economically important meat traits such as tenderness and fat content (marbling), is thyroglobulin (TG). Therefore, the aim of this study was to determine the existence of TG gene polymorphism and its influence on carcass quality and marbling score in Simmental and Holstein crossbreeds. TG gene polymorphism was found in crosses of both sexes and only CC and CT genotypes were identified, while the TT genotype was not determined. In the observed sample, a higher frequency of allelic variant C and genotype CC was found. Statistically significant influence of TG gene and sex on carcasses of Simmental and Holstein cattle breeds was not found. The interaction of TG gene and sex on the carcass quality between male and female crossbreds of both genotypes was statistically significant for live weight at slaughter and daily gain, hot and cold carcass weight, all of which were higher in male individuals. The interaction of TG gene and sex of crossbreds on fat content, EUROP classification and marbling score was not statistically significant.
