Layer feed containing NANO-Se

Abstract

The invention relates to a layer feed containing NANO-Se. The selenium-rich layer feed is prepared by breaking and smashing 60 parts of corn and 23 parts of soybean meal into 40-mesh particles, adding 4.6 parts of wheat bran, 12 parts of mixtures and 0.4 parts of NANO-Se, and mixing in a mixer for 20min. The NANO-Se (red elemental selenium) is high in bioavailability and very low in acute toxicity. As the use amount of NANO-Se (red elemental selenium) is small and no toxicity is caused to hens, the egg yield is not affected, the nutritional level of amino acid in the hens is raised, and the egg production is facilitated.

Description

technical field [0001] The invention relates to the field of livestock and poultry feeding, in particular to a layer hen feed containing nano-selenium. technical background [0002] Selenium can reduce oxidized low-density lipoprotein, reduce the deposition of lipids on the arterial wall, protect the integrity of the endothelial cell membrane on the blood vessel wall, reduce thrombosis, prevent myocardial infarction, supplement selenium to patients with selenium deficiency, and increase the blood platelet count. The activity of glutathione peroxidase inhibits platelet aggregation and prevents the formation of platelet thrombus in arteries, thereby preventing the occurrence of coronary heart disease. Selenium also participates in the oxidative phosphorylation and energy metabolism of cells, and eliminates free radicals while lipid peroxidation, thereby maintaining the normal structure, metabolism and function of the myocardium. In conclusion, quantitative selenium su...
