title: [Increase of nutritive value of poultry egg by of vitamin fortification of laid-hens diets].
abstract: Real content of vitamins A, E, B1 and B2 in hen's eggs from different poultry farms and personal farm varies in wide range and differs from the data of national food chemical tables. Elevated nutritive value eggs with maximal vitamin content may be obtained from hens fed diets with optimal vitamin level. Such way fortified one egg contributes 30% of recommended daily intake of vitamin E, about 10% of vitamins A and B2, 3% of vitamin B1. Intensification of egg yolk pigmentation by means of carotenoids additives to hens ration leads to their 10-fold increase comparing with the data of food chemical tables. Coloured egg provides for 5-10% of carotenoids adequate daily intake.
