Fat colour score (FCS), and carotene concentration and their relationships were examined in carcasses of Jersey, Limousin, and F1 heifers and in biopsy samples of Jersey, 3/4 Jersey, and 3/4 Limousin weaners. Results demonstrate significant differences between all breeds in carotene concentration and FCS. High correlations between FCS and B-carotene concentration were also demonstrated. Sex differences in FCS and B-carotene concentration were not significant. The shape of the distributions of beta-carotene content in fat varied between the breeds. High outliers were observed for the pure Jersey, 3/4 Jersey, and F1 and not observed in Limousin and 3/4 Limousin. Based on this preliminary data, we confirmed that beta-carotene concentration in fat of cattle has a genetic basis and hypothesise that a major gene(s) may be involved.
