Owing to its wholesomeness and good taste, meat of goats and lambs is an increasingly more important in human nutrition. It is characterized by excellent nutritive value and high digestibility. It is also relatively rich in mineral compounds. The aim of this study has been to determine the content of some elements in muscles, liver and kidneys of male and felame kid goats, fattened to 150 day of life. The animals received full-ration mixture containing 169 g total protein and 6.0 MJ net energy. The mixture was given ad libitum and supplemented with meadow hay as bulk feed. During the whole period of fattening, the animals were kept under the conventional housing system. Samples for analysis were taken from adductor femoris muscles, liver and kidneys. The muscle tissue of the analysed male goats contained less Cd (0.002 mg kg-1 ± 0.004) than that of the female goats (0.003 mg kg-1 ± 0.001). In turn, the level Pb was lower in the female goats (0.019 mg kg-1 versus 0.026 mg kg-1 in male goats), although the difference was statistically non-significant. In the internal organs, more Cd occurred in kidneys than in the liver, unlike Pb. The concentration Pb was higher in kidneys of the male than female goats (0.073 mg kg-1 ± 0.02), whereas the level of this element the liver was identical in both groups (0.084 mg kg-1 ). In the muscule tissue, the sex differentiated the content of Fe (p = 0.01) as well as Mg and Zn (p = 0.05). The liver accumulated not only Pb and Cd, but also Cu and Zn. The concentration Cu in the liver of female goats was higher (146.79 mg kg-1 at p = 0.01) than in male goats by about 50 mg kg-1. High disproportions between the sexes in the content of Fe in the liver were observed: 36.30 mg kg-1 for female goats and 21.99 mg kg-1 for male goats (p = 0,01). In kidneys, however, the concentration of Ca was very high, particularly for female goats particularly (81.01 ± 26.55 mg kg-1).
