Abstract
Eggs stand out because of their considerable nutritional value; they constitute a component of many food products. This is for the reason that they contain many necessary ingredients for life including minerals. The mineral composition of table eggs changes and depends, to a large extent, from nutritional and genetic factors. The objective of the research study was to compare the content of nine macro- and microelements in the contents of eggs from the selected autochthonous hen breeds: Greenleg Partridge, Yellowleg Partridge, Rhode Island Red, and Sussex, which were kept under ecological conditions and fed in a uniform way. The selected elements were determined using an AAS method. As regards the content of elements, a significant differentiation of eggs was found depending on the hen breed. The highest amounts of the following elements were found in the contents of Sussex eggs: magnesium (161.13 mg·kg-1), copper (1.46 mg·kg-1), and selenium (0.35 mg·kg-1). The eggs pf the Rhode Island Red hens had the highest content of potassium (1377.02 mg·kg-1), iron (47.63 mg·kg-1), and manganese (151.50 mg·kg-1). The Greenleg Partridge hen laid eggs the contents of which had the highest level of zinc (23.33 mg·kg-1) and the Yellowleg Partridge hen laid eggs with the contents containing the highest amounts of sodium (1820.92 mg·kg-1) and calcium (618.21 mg·kg-1).
