title: Iodine concentration in fodder influences the dynamics of iodine levels in hen's egg components.
abstract: In this study we determined the availability and accumulation of iodine in selected structures in hen's eggs: yolk, albumen, and eggshells. Iodine was administered as a yeast-derived biological complex mixed in standard fodder mix "DJ" to laying hens in their maximum egg yield period. The feeding period was sustained for 12 weeks, resulting in iodine enrichment in yolk and eggshells. These results suggest that iodine-enriched yeast can be added to fodder mix and premix (mineral-vitamin) given to monogastric animals such as poultry and pigs.
