The aim of this study was to determine the concentrations of various trace elements in muscles with different oxidative/glycolytic profiles (cardiac [CA]; diaphragm [DI], as oxidative; trapezius [TR], as intermediate oxidative/glycolytic; and semimembranosus [SM], as glycolytic muscle) of ten dairy-aptitude (Holstein-Friesian, HF), ten beef-aptitude (Galician Blonde, GB) and ten cross-breed (GBxHF) calves. The type of muscle was a highly significant factor in relation to the concentrations of all elements, whereas breed was only significant for Fe, Mn and Zn in the SM muscle. The concentrations of the main trace elements (Cu, Fe, Se and Zn) were significantly lower in GB and GBxHF than in HF, that were mainly associated with differences in the oxidative/glycolytic profile, probably due to the muscular hypertrophy characteristic of heavily muscled breeds. The pattern of distribution was similar in all breeds, with significantly higher concentrations in the CA muscle, followed by the DI; trace element concentrations in the SM and TR muscles were very similar.

这项研究的目的是确定具有不同氧化/糖酵解曲线的肌肉中各种微量元素的浓度（心脏[CA]；隔膜[DI]为氧化性；斜方肌[TR]作为中间氧化/糖解性；半膜[ SM]，作为糖酵解肌）的十头乳牛（Holstein-Friesian，HF），十头牛肉（Galician Blonde，GB）和十头杂种（GBxHF）牛犊。肌肉的类型是与所有元素浓度相关的高度重要因素，而繁殖仅对SM肌肉中的Fe，Mn和Zn有意义。GB和GBxHF中主要微量元素（Cu，Fe，Se和Zn）的浓度显着低于HF，这主要与氧化/糖酵解曲线的差异有关，可能是由于肌肉发达的品种的肌肉肥大所致。在所有品种中，分布方式都相似，CA肌肉中的浓度明显更高，其次是DI。SM和TR肌肉中的微量元素浓度非常相似。
