Concentration of macro and mikrominerals in muscles of kids

The aim of this research was to determine the influence that breed has on the concentration of macro and microelements in different groups of muscles in kids. Accordingly, the following meat samples were taken from 27 kids (14 Saanen and 13 Alpine): shoulder-blade muscles – m. deltoideus, m. subscapularis and m. triceps brachi ; back muscles – m. longissimus dorsi, m. spinalis et semispinalis, m. trapezius and m. romboideus ; thigh muscles – m. biceps femoris, m. semitendineus and m. gastrocnemius. Initially, all visible elements of fat, cartilage and bone were removed manually. Samples were then minced, homogenized, packed in plastic bags and deep frozen in preparation for analysis. Mineral concentrations were determined using the atomic absorption method (AAS) on PU-9100X. Results obtained show that the highest concentration of macroelements found in all groups of muscles were K, Na and P, while the most widely represented among microelements were Zn, Fe and Cu. The research failed to establish that breed has a significant influence on the concentration of macroelements in the investigated groups of kid muscles. However, it was found that significant differences do exist between breeds with regard to the concentration of Zn and Fe in back muscles, and of Zn and Cu in shoulder-blade muscles. Also established were correlation coefficients between macro and microminerals between different groups of kid muscles.
