Mineral-humic preparations Humokarbowit (HKW) and Humobentofet (HBF) were used in feeding of reproductive laying hens Lohmann Brown. The effect of these preparations on microelement composition of eggs was investigated. The content of microelements in hens diet, egg albumen and eggshell was determined by ICP-MS technique and relative bioaccumulation coefficient (RBC) was evaluated. The humic preparations significantly increased selenium and decreased molybdenum concentration in egg albumen. Increase of selenium and iron content in egg yolk and increase of iron concentration in eggshells was observed. The preparations did not influence the content of such elements as Cr, Co, Cu, I, Mn, Zn. The highest levels of RBC were found for selenium and iodine and the lowest for manganese. |
