ABSTRACT

Standard mineral–vitamin premix (with 15 mg of Se and 150 mg of I) was applied to NK–Lohmann feed for the control group (C), and enriched premix, with doubled concentration of Se (30 mg·kg^–1) and I (300 mg·kg^–1), was fed to the experimental group (E) of Lohmann Brown laying hens in an egg production farm. The enriched premix contained also 50% more vitamin E (1500 mg·kg^–1). After four weeks of application of the increased levels of Se and I, increased concentrations of selenium, by mean 13.9% ( = 0.401 mg∙kg^–1 of wet weight), and of iodine, by 52.6% ( = 1.055 mg·kg^–1 of wet weight), were observed in egg content of the experimental group. No antagonistic effects were observed of selenium or iodine against the egg – content concentration of calcium, magnesium, manganese or copp

Key words: hen, egg, selenium, iodine.
