Abstract

The invention belongs to the field of nutritional health and discloses a selenium-enriched feed for laying hens and application of the selenium-enriched feed. The selenium-enriched feed for the layinghens is prepared from the components: polysaccharide nano-selenium and basic chicken rations, wherein the content of the polysaccharide nano-selenium in the selenium-enriched feed for the laying hensis calculated according to a selenium amount, i.e., 0.05mg / kg to 1mg / kg. According to the selenium-enriched feed disclosed by the invention, the selenium content is low, the selenium conversion ratiois high, the selenium enriching effect of eggs is remarkable, the selenium content of produced eggs is increased by 222.9%, 350.7% and 235.2% separately compared with that of eggs produced by blank chicken feeds when the selenium amount of lentinan nano-selenium, carboxymethyl pachymaran nano-selenium and chitosan nano-selenium in the chicken feed is 0.345mg / kg, and the regulation and control onenriched selenium amount can be carried out in practical application in future in view of different objects.

Description

technical field [0001] The invention belongs to the field of nutrition and health, and in particular relates to a selenium-enriched laying hen feed and application thereof. Background technique [0002] Selenium is an indispensable trace element in the human body. It is an important component of glutathione peroxidase, an antioxidant in red blood cells. Sufficient selenium can promote glutathione peroxidase to effectively convert hydrogen into water in the human body; Selenium is also a component of superoxide dismutase, which can eliminate free radicals and maintain normal levels of catecholamines involved in the regulation of blood pressure in the human body; selenium can also eliminate toxins in the body, resist oxidation, effectively inhibit the production of lipid peroxides, and prevent blood clots , remove cholesterol, promote immunoglobulin synthesis, and enhance human immune function. In addition, a variety of enzymes containing selenium can regulate the work of the...
