Essential elements content of hen egg-white in Markazi province (Iran)

Abstract

Eggs are among the nutrient-rich food in the human daily diet. Knowledge of the essential element content of hen eggs is required for different purposes for the nutritional value for human consumption. Within the current study, content of elements in hen egg-white from 32 industrial poultry farms was investigated by inductively coupled plasma optical emission spectrometry. Eggs were sampled in the Markazi province (Iran), in autumn 2014. The results of our study show that, except about P, egg-whites produced in Markazi province are poor sources for supply essential trace element. Thus, nutritionists have focused their research on the impact of supplementing the diet of the hen with different levels of trace elements.
