title: [Influence of long-term chitosan feeding of laying hens].
abstract: Under insufficient vitamin content in a diet of laying hens in compliance with lowered vitamins A, E and carotenoids content in an egg yolk acid- and water-soluble chitosan feeding (10 and 20 mg per 1 kg body mass) within 6-9 months did not render appreciable influence on these vitamins egg content. Long-term inclusion of a sorbent in a forage was not reflected in vitamin B2 level in a whole egg, blood serum and tissues of hens. Chitosan intake didn't lead to total lipids and phospholipids concentration in a whole egg. Under 15 per cent decrease of the sum of polyunsaturated fat acids its administration lead to 24 per cent increase of omega-3 polyunsaturated fat acids in the whole egg.
