Minerals in meat vary with different extrinsic and intrinsic sources; therefore, we aimed to quantify different sources of variation in mineral profile of beef. Longissimus thoracis muscle (N.182) from young bulls and heifers was analysed using ICP‐OES for 6 macrominerals, 5 essential microminerals and 9 environmental microminerals. Results of mixed models show that breed and sex have little effect on mineral profile. Major sources of variation, such as farm, individual animal within farm and side/sample within animal, differed markedly from mineral to mineral, affecting reproducibility coefficients. Multivariate factor analysis revealed that five latent factors explained 69% of the co‐variance of 20 minerals. The first was a quantitative factor, followed by others based on Na‐Fe‐Cu, on K‐B‐Pb, on Fe‐Mn and on Zn content, respectively. In conclusion, minerals’ major source of variation depends on complex relationships between the animal’s genetics, physiology, farm environment, management and feeding, whose understanding is favoured by latent factor analyses.

探索农场，品种，性别和动物对牛肉详细矿物质特征的影响及其潜在的解释因素

肉中的矿物质因外在和内在来源的不同而有所不同。因此，我们旨在量化牛肉矿物质剖面变化的不同来源。胸最长肌使用ICP-OES分析了来自年轻公牛和小母牛的肌肉（N.182）的6个大型矿物质，5个基本微量矿物质和9个环境微量矿物质。混合模型的结果表明，品种和性别对矿物分布几乎没有影响。变异的主要来源，例如农场，农场内的单个动物以及动物内的侧面/样本，因矿物而异，影响再现性系数。多元因素分析显示，五个潜在因素解释了20种矿物的协方差的69％。第一个是定量因子，其次是基于Na-Fe-Cu，K-B-Pb，Fe-Mn和Zn含量的其他因子。总之，矿物质的主要变异来源取决于动物的遗传学，生理学，农场环境，管理和喂养之间的复杂关系，
