Tenderloin (T), eye of rump (E), striploin (S), eye round (ER), tri-tip (TT), rib-eye roll (RR) and three rib plate-flank on (RP) meat cuts were evaluated. Selenium contents ranged between 0.42 and 1.20 mg/kg wet tissue (wt) in Hereford (H) breed and between 0.49 and 1.3 mg/kg wt in Braford (B) breed. In H and B breeds, T, TT and RP, and TT and RP were the richest cuts in selenium, respectively. Copper contents ranged between 0.25 and 1.04 mg/kg wt in H, and between 0.19 and 1.09 mg/kg wt in B. In H breed, RP had significantly more Cu than ER, TT, and RR. In B breed, ER and RR show a significant lower Cu level in comparison to the other meat cuts. Zinc contents ranged between 23 and 72.7 mg/kg wt in H, and between 23 and 63.9 mg/kg wt in B. RP is the richest cut in Zn compared to the other cuts in the two breeds. Iron contents ranged between 16.4 and 48.2 mg/kg wt in H, and between 14.2 and 47.9 mg/kg wt in B. In H breed, RR shows a lower content compared to the other cuts, except RP and S. In B breed, RR had the lowest level of Fe compared to the other cuts, except RP and T. Manganese contents ranged between 0.05 and 0.17 mg/kg wt in H, and between 0.04 and 0.48 mg/kg wt in B. In H no differences were detected between cuts. In B breed, ER cut shows the highest level of Mn.  © 2009 Elsevier Ltd.
