Pilarczyk Department of Ruminant Science, West Pomeranian University of Technology in Szczecin, Judyma 10 Street, 71-460 Szczecin, Poland Journal Article 2014 10 10 Concentrations of major nutritional and trace elements (Ca, P, Mg, Na, K, Fe, Zn, Cu, Mn, Se,<br />Co, Cr, Ni, Sr, Ba) and toxic heavy metals (Cd, Pb) were analyzed in the meat of Limousin, Red Angus and<br />Salers bulls. Elements were determined using inductively coupled plasma emission atomic spectrometry. The<br />conducted research showed that the meat of compared breeds differed in the concentrations of Cu, Zn, Fe, Se<br />and K. The meat from Limousin bulls had significantly lower Zn (P<0.001) and Cu (P<0.05) contents than<br />that of Red Angus and Salers bulls. Moreover, the meat of Red Angus bulls was characterized by a significantly<br />(P<0.001) lower K content and significantly (P<0.05) higher Fe content compared to those in the Limousin<br />and Salers bulls as well as significantly (P<0.05) higher Se content in comparison with the Salers bulls. No<br />breed differences in the concentrations of Pb and Cd were found; however, the Pb concentration in meat was<br />higher than the recommended standards. In the meat of all three breeds, the significant strong positive correlations<br />were observed between the contents of Pb-Cd, Pb-Ni, Cd-Ni and K-P. The correlations between other elements<br />within each of the breeds separately were also found. https://ijer.ut.ac.ir/article_785_5a06d47693a1aebb55f076158d51d4d1.pdf
